Abstract:
In the practical implementation of the sequential wire electrical discharge machining – pulsed electrochemical machining (WEDM – PECM) technology and in order to perform high quality electrochemical processing, there is a need for the real-time operational control of electrical parameters of inter-electrode space and corresponding adaptive correction of amplitude-frequency power supply parameters (AFPSP). In the context presented by the authors, a mathematical apparatus and an algorithm of operational galvanostatic mode monitoring of anode dissolution using wire electrode-tool are proposed. This will allow adaptive adjustment of AFPSP to ensure controlled passage of electrochemical reactions and significantly increase process stability, dissolved surface layer thickness uniformity along entire electrode tool movement trajectory and resulting surface quality.

Abstract:
This paper develops an array micro-grooves manufacturing method using micro electrochemical machining (ECM) with disk electrode, which is prepared by in-situ micro wire electrical discharge machining (WEDM). This technology focuses on the difficulty of array structure manufacture in micro-electro-mechanical systems (MEMS). A micro-ECM system is built based on the micro-WEDM machine to achieve high precision processing of the array micro-grooves. Since micro-WEDM has good performance in high precision machining of the rotating structure, single and multi-edge disk electrodes can be fabricated in-situ using graphite. The as-prepared disk tool electrode is directly used for micro-electrochemical milling of the array micro-grooves without disassembling away from the device, which avoids the positioning error caused by the re-clamping of the disk electrode. With the advantages of high surface quality and no electrode loss, micro-ECM improves the manufacture performance of the micro-parts. Through wire path optimization, the shape accuracy of the disk edge is improved. After the research of the micro-ECM parameters, the process is improved, and finally, the high precision array micro-grooves are obtained. This method combines the advantages of micro-WEDM and disk electrode micro-ECM milling, and it is convenient for large-scale manufacture of array micro-structures on micro-parts and MEMS.

Abstract:
Wire electrochemical machining (WECM) has great advantages and potential for fabricating parts with ruled surfaces made of difficult-to-machine materials. Characterized by a relatively short flow path, a pulsating radial electrolyte supply in WECM is proposed to improve the machining capability for thick workpieces. The tool is a tube electrode with a line of micro-holes on cylindrical surface. This paper introduces research into the processing of micro-holes in the tube electrode using a rotating helical electrode. The quantitative relationship among the feed rate, the applied voltage, and the diameter of the outlet holes was determined experimentally. A tube electrode with holes of varying diameters was fabricated by adjusting the applied voltage. Using it as a tool electrode, kerfs with a length of 10 mm and an averaged width of 0.903 mm were machined at a feed rate of 6 μm/s in a 30 mm-thick block, and there was no short circuit during processing. It was shown experimentally that using a tube electrode with holes of varying diameters as a tool electrode provides better process capacity for pulsating radial electrolyte supply in WECM.

Abstract:
<p>Amoxicillin is one of β-lactam antibiotic in penicillin groups which their presence in surface water and wastewater not only affects water quality but also causes long-term adverse effects on ecosystems and human health due to their resistance to natural biodegradation. The processing of organic waste electrochemically has the advantage of cheap and efficient cost, exhaust gas that does not contain toxic and hazardous materials. We have studied the process of amoxicillin electro-oxidation mediated by a cobalt (III) ion called an electrochemical oxidation process mediated (MEO) in a voltammetry study using a platinum working electrode, Pt/Co(OH)<sub>2</sub> and Pt/Co in various supporting electrolytes such as KNO<sub>3</sub>, NaClO<sub>4</sub>, Na<sub>2</sub>SO<sub>4</sub> and phosphate buffer solution with concentrations 0.10 M. The results show that the amoxicillin oxidation peaks using the above-mentioned working electrode in various electrolyte solutions are in the potential range of 500-670 mV (Ag/AgCl). The presence of cobalt ions forming complex compounds with amoxicillin causes the oxidation current decreasing that indicates the presence of degradation to amoxicillin.</p>

Abstract:
It is of great significance to prepare electrochemical glucose sensors with high selectivity and stability via effective and rapid methods. In this work, the self-support electrode with copper and nickel-based oxide is prepared by chemical-etching reaction which occurred under the property of electrochemical potential difference. In this processing, nickel foam is etched selectively by Cu[Formula: see text] ions and they not only act as self-supporting electrode substrate, but also as nickel ions precursor of NiO. Moreover, the reaction can be completely satisfied on 30 min at room temperature. As a self-supporting electrode nonenzymic glucose electrochemical sensor, the electrode exhibited a wide linear range (0.04–3.00[Formula: see text]mM), low detection limit (0.02[Formula: see text]mM) with high sensitivity of 1096[Formula: see text][Formula: see text] and good selectivity, repeatability and stability. Furthermore, the application of the prepared sensor provides an avenue for the application of the transition metal materials in the field of electrochemical sensing.

Abstract:
During the wire electrical discharge machining (WEDM) process, a large number of discharge pits and a recast layer are easily generated on the workpiece surface, resulting in high surface roughness. A discharge forming cutting-electrochemical machining method for fabricating single-crystal silicon is proposed in this study to solve this problem. On the same processing equipment, single-crystal silicon is first cut using the discharge forming cutting method. Second, electrochemical anodic reaction technology is used to dissolve the discharge pits and recast layer on the single-crystal silicon surface. The machining mechanism of this process, the surface elements of the processed single-crystal silicon and a comparison of the kerf width are analyzed through experiments. On this basis, the influence of the movement speed of the copper foil electrode during electrochemical anodic dissolution on the final surface roughness is qualitatively analyzed. The experimental results show that discharge forming cutting-electrochemical machining can effectively eliminate the electrical discharge pits and recast layer, which are caused by electric discharge cutting, on the surface of single-crystal silicon, thereby reducing the surface roughness of the workpiece.

Abstract:
Carbon-based electrodes combined with fast-scan cyclic voltammetry (FSCV) enable neurochemical sensing with high spatiotemporal resolution and sensitivity. While their attractive electrochemical and conductive properties have established a long history of use in the detection of neurotransmitters both in vitro and in vivo, carbon fiber microelectrodes (CFMEs) also have limitations in their fabrication, flexibility, and chronic stability. Diamond is a form of carbon with a more rigid bonding structure (sp3-hybridized) which can become conductive when boron-doped. Boron-doped diamond (BDD) is characterized by an extremely wide potential window, low background current, and good biocompatibility. Additionally, methods for processing and patterning diamond allow for high-throughput batch fabrication and customization of electrode arrays with unique architectures. While tradeoffs in sensitivity can undermine the advantages of BDD as a neurochemical sensor, there are numerous untapped opportunities to further improve performance, including anodic pretreatment, or optimization of the FSCV waveform, instrumentation, sp2/sp3 character, doping, surface characteristics, and signal processing. Here, we review the state-of-the-art in diamond electrodes for neurochemical sensing and discuss potential opportunities for future advancements of the technology. We highlight our team’s progress with the development of an all-diamond fiber ultramicroelectrode as a novel approach to advance the performance and applications of diamond-based neurochemical sensors.

Abstract:
Discovered in 1930, metal processing by electrolysis processes in aqueous solutions, are being intensely studied starting with 1960, so that now they have a wide diversity and industrial applicability. The present paper illustrates some theoretical considerations regarding specific electrode processes of the aqueous solutions electrolysis and the I=f (U) characteristics of the Me/VGS/E electrochemical system thus establishing the forming conditions of electrolytic plasma (PE). The continuous and stable character of the deposited layer (VGS) and of the shell formed by the electrolytic plasma will contribute to the rapid heating of the metal electrode, under the influence of the three heat flows qa, ql and qs. Plasma electrolytic saturation phenomena (PES) and the formation of oxides on the metal surface (PEO), represent the two main directions of plasma electrolytic deposition (PED).

Abstract:
This thesis presents work relating to the fabrication of novel thin film electrodes for energy storage applications, with a focus on low cost, nanostructured transition metal oxides, and electrode manufacture by atomised spray deposition. Iron oxide (FeOx) nanowires were synthesised hydrothermally and combined with multi-walled carbon nanotubes (MWNT) in sprayed electrodes, which provided the necessary conductivity enhancement for effective energy storage. The spray processing technique allowed for facile control over the relative fraction of MWNTs in the sprayed electrodes. Optimised electrodes were investigated in a range of aqueous electrolytes, and the best energy storage behaviour occurred in Na2SO3 with a maximum capacitance from cyclic voltammetry of 312 Fg-1 at a scan rate of 2 mVs-1. The FeOx/MWNT electrodes were investigated for their suitability as lithium-ion battery anodes and showed reasonable energy storage behaviour. Nickel oxide (NiO) electrodes were manufactured by hydrothermal synthesis and annealing followed atomised spray deposition. The performance of the NiO electrodes was enhanced though combination with aqueous graphene suspensions, produced in-house by ultrasonic exfoliation of graphite. The processing route used to combine the nanomaterials was considered and a co-synthesis route resulted in the best performing electrodes. Different substrates were investigated, as the most commonly used Ni-foam substrate reacted with the basic electrolytes necessary for electrochemical activity of NiO. NiO/graphene electrodes showed charge/discharge capacitances of up to 571 Fg-1 at a current density of 10 Ag-1, which was maintained at over 300 F/g at a very high current density of 100 Ag-1. Asymmetric supercapacitor devices were constructed using various combinations of FeOx, NiO, and commercial carbon black electrodes to extend the operating potential window beyond the ~1.23 V limit of symmetric aqueous-electrolyte devices. Power densities of over 20 kWkg-1 were achieved for an FeOx/MWNT-carbon device, which was comparable with current commercial carbon-only supercapacitors.

At present the methods used to machine micro hole are ultrasonic machining, drilling machining, laser beam machining, grinding machining, electron beam machining and electrical discharge machining. Among these, Micro-EDM not only is able to process high precision machining, but also cost down. It’s a technique with deep development well. Generally, there are two methods to machine microelectrode with Micro-EDM which are block electrode machining and wire electrode machining with wire guide. The former has question of consumed; the latter causes the wire that is drawn out continuously, the wire consumed can be regard. This research had designed a revolving organization and build over a precision wire cut machine to process out cylinder electrode. Therefore, to reach the precision the Design target is simple structure and assembled easily. The advantage of the design is that the wire cut machine can easily be used to process out cylinder electrode without complicated design and parts. Although it can not reach the precision with the wire guide, but we has proved its practicable. At least, the electrode of Tungsten carbide can be process fromψ0.5mm to 69μm, length 0.511mm, L/D≒7.4. And machining micro hole further, due to the process energy can’t be down enough, the machined hole can only reach 150μm.

Nowadays, the researches and developments of renewable energy have become the universal consensus. Among them, the developments of solar cell attract the greatest attention. In the process of making solar cell, the cutting process of silicon ingot is the key to determine the cost. Multi-wire saw has been used in the traditional cutting to conduct machining process. Its advantage is to multi-wire-type processing, which heighten the processing efficiency. However, multi wire requires great tension and produces stress that could easily damage the silicon ingot. In addition, during the process, abrasive could not be used completely. The complicated recycle processes of abrasive contaminate the environment. Thus, in recent years, related research proposed in the literature, by using wire electrical discharge machining (WEDM) cutting silicon ingot, this method can effectively improve the shortcomings multi-wire saw. WEDM has been applied onto the single-crystal silicon cutting. Most researches adopted single-crystal silicon as the process material. However, it is hard to find a literature review on the machining characteristics of a polycrystalline silicon surface and the quality improvements after processing. The main reasons of polycrystalline silicon are changing boundaries, high electrical resistance and other characteristics, which lead WEDM can not be process smoothly. Polycrystalline silicon manufacturing process is simple, lower cost, stable photoelectric efficiency and other advantages. Therefore, a new method to improve the polycrystalline silicon processing problems needs to be developed. This thesis adopts machining characteristics of polycrystalline silicon research by WEDM and electrochemical grinding (ECG) these two methods. This paper divided into two research directions. The first part discusses when the polycrystalline silicon by using WEDM processing, the impact of discharge parameters on the polycrystalline silicon and the adjustments of phosphorous dielectric improve its processing efficiency and processing characteristics. The second part is the application of ECG surface defects after WEDM be grinded, it improves the removal of surface roughness and affected layer by using Taguchi-method experiment planning, the main factor affects the analysis process to get through. Follow added graphene in dielectric. By using the high hardness and high lubricity of graphene to improve processing characteristics of the original surface and explore the impact of process parameters for the processing. After the experiments by this thesis, it is sure that in the WEDM processing, phosphorous dielectric improves the discharge process effectively and makes the discharge energy booster to enhance conductivity. Under the no-changing existed processing parameters condition, it improves the cutting speed and reduces kerf loss. In the ECG processing, by adding graphene, the surface problems effectively improved after WEDM machining residues and reduce friction force during processing and it enhances the grinding tool life. It is expected the results of this thesis could be referenced for the future research in both industrials and academic field.

AbstractToday, lithium-ion batteries are a promising technology in the evolution of electro mobility, but still have potential for improvement in terms of performance, safety and cost. In order to exploit this potential, one promising approach is the replacement of liquid electrolyte with solid-state electrolyte and the use of lithium metal electrode as an anode instead of graphite based anodes. Solid-state electrolytes and the lithium metal anode have favorable electrochemical properties and therefore enable significantly increased energy densities with inherent safety. However, these materials are both, mechanically and chemically sensitive. Therefore, material-adapted processes are essential to ensure quality-assured manufacturing of all-solid-state lithium-ion battery cells. This paper presents the development of a scaled and flexible automated assembly station adapted to the challenging properties of the new all-solid-state battery materials. In the station various handling and gripping techniques are evaluated and qualified for assembly of all-solid-state battery cells. To qualify the techniques, image processing is set up as a quality measurement technology. The paper also discusses the challenges of enclosing the entire assembly station in inert gas atmosphere to avoid side reactions and contamination of the chemically reactive materials.

In this experiment, the work piece is electrochemically machined which finds its applications in brine heaters, heat exchangers, propeller shafts, and pumps. The process is carried out using sodium chloride electrolyte and copper beryllium wire as tool electrode which is heat treated in three different methods which are annealing, quenching, and normalizing. The response parameters like theoretical and experimental metal removal rate have been measured and studied by varying machining parameters like voltage, frequency, concentration of electrolyte, and duty cycle. Based on the values obtained from the experiment, it is found that quenched tool electrodes have better machining capabilities than the other heat-treated tool electrodes and untreated tool electrodes.

Abstract:
Energy storage devices have acquired great research attention in the fabrication of ultra-high efficient supercapacitors. In order to enhance the electrochemical performance of the supercapacitors, different electrodes have been fabricated using various nanomaterials with precisely controlled morphologies and interfaces. Nevertheless, the low-dimensional nanomaterials still suffer from the factors such as severe re-stacking, non-homogeneous aggregation, and low contacts during the processing and assembly. These bottle-neck problems essentially lead to the hindrance of transport of electrons and/or ions in the energy devices. In this direction, recently, the bioinspired nanomaterials are emerging as the potential candidates to overcome the said disadvantages of the chemically derived low dimensional nanomaterials. The well-aligned or highly oriented bioinspired nanostructures found to effectively promote the transport of electrons, facilitate the ion diffusions through the hierarchical pores and provide the large specific surface area for their interfacial interactions with the surroundings. Moreover, the nanoscale materials can be easily tuned or engineered for their physicochemical properties, thereby they can be potentially used in many device applications. In this context, this chapter is intended to highlight the recent progress in bioinspired nanomaterials towards developing the electrode materials for supercapacitors with the emphasize on the fundamental understandings between their structural properties and electrochemical performances. Finally, it concludes with an outlook on the next generation nanostructured electrodes to design the ultra high-efficient supercapacitors.

Abstract Nickel-based alloys represented by Inconel are materials with excellent high-temperature characteristics, and are widely used in the aerospace industry, such as aircraft and rocket engine parts. On the other hand, it is known as a typical difficult-to-cut material. Furthermore, in machining and electric discharge machining (EDM), the machining speed is slow and tool or electrode wear is a big problem. Meanwhile, electrochemical machining (ECM) using electrochemical reaction is not affected by the hardness of the material, does not generate a heat-affected layer on the workpiece surface, and has no tool wear. So, it is considered that ECM is suitable for machining difficult-to-cut materials. Therefore, in this study, focusing on the nickel-based alloy Inconel718 (Alloy718), we conducted a machining experiment using NaNO3 aqueous solution by wire ECM using a thin wire (mainly tungsten) as a tool electrode, and investigated the ECM characteristics. Wire ECM can be machined like wire EDM, and high-efficiency machining is possible by using a pulse power supply. As a result, it was found that increasing the voltage, electrolyte concentration, electrolyte supply pressure, and diameter of wire increases the current flowing between the electrodes and has the effect of promoting machining. In addition to simple cutting, the possibility of being effective not only for grooving but also for cutting complex shapes was shown.

Nanotwins in metallic nanowires can improve mechanical strength and maintain high electrical conductivity. We demonstrated a method of pulse laser assisted electrodeposition, which can generate dense nanotwins with different directions in copper nanowires of uniform length. Transmission electron microcopy characterization shows at lower electrochemical potential of −0.2 Volt, nanotwins tend to align along the longitudinal direction of the nanowires whereas at the high potential −0.8 Volt, nanotwins of {111}/<112> type that cross the width of the wire are formed. We investigated the two types of nanotwins by comparing the microstructures under different electrochemistry and laser setting. Two different mechanisms are proposed for two kinds of nanotwin — annealing twins and growth twins.

Abstract:
Components with best surface integrities — without any white layer or mechanically damaged rim zones — and regardless of mechanical properties of the material can be produced with electrochemical machining (ECM). Wire ECM combines the outstanding advantages of the ECM working principle with the kinematic of wire electrical discharge machining (wire EDM). A task-specific tool design — such as for classical sinking ECM — is not required for cutting 2.5-dimensional geometries like fir tree slots in turbine discs. Established manufacturing technologies for fir trees are broaching and recently wire EDM. However, high requirements on surface integrity of these turbine parts afford cost intensive finishing processes. Thus, wire ECM could be an attractive cost efficient alternative manufacturing process. Due to an insufficient flushing concept, a process development of wire ECM for fir tree slots with relevant disc heights failed in the past. A combination of an axial flushing with rotating structured electrode provides a promising approach to meet these challenges. Therefore, this paper presents investigations of cutting Inconel 718 direct-aged using the new flushing principle. Workpieces with heights up to 40 mm are machined, which is comparable to a low pressure turbine disc height. Reachable feed rates respectively cutting rates are presented. Due to the process specific edge rounding, the formation of the leading edges is examined. Finally, the evolving surface integrities with the help of surface roughness, cross sections and residual stresses are investigated and discussed.

Abstract:
The development of novel characterization techniques is critical for understanding the fundamentals of material systems. Bioinspired systems are regularly implemented but poorly defined through quantitative measurement. In an effort to specify the coupling between multiple domains seen in biologically inspired systems, high resolution measurement systems capable of simultaneously measuring various phenomena such as electrical, chemical, mechanical, or optical signals is required. Scanning electrochemical microscopy (SECM) and shear-force (SF) imaging are nanoscale measurement techniques which examine the electrochemical behavior at a liquid-solid or liquid-liquid interface and simultaneously probe morphological features. It is therefore a suitable measurement technique for understanding biological phenomena. SF imaging is a high resolution technique, allowing for nanoscale measurement of extensional actuation in materials with high signal to noise ratio. The sensing capabilities of SECM-SF techniques are dependent on the characteristics of the micro-scale electrodes (ultramicroelectrodes or UMEs) used to investigate surfaces. Current limitations to this technique are due to the fabrication process which introduces structural damping, reducing the signal produced. Additionally, despite the high cost of materials and processing, contemporary processes only produce a 10% yield. This article demonstrates a UME fabrication process with a 60% yield as well as improved amplitude (250% increase) and sensitivity (210% increase) during SF imaging. This process is expected to improve the signal to noise ratio of SF-based measurement systems. With these improvements, SECM-SF could become a more suitable technique for measuring cell or tissue activity, corrosion of materials, or coupled mechanics of synthetic faradaic materials.
