Abstract:
Based on a well-designed growth procedure, a tri-material, namely, a three-layer boron-doped micro-crystalline, undoped micro-crystalline and undoped nano-crystalline composite diamond film, is deposited on the pretreated WC–6 wt% Co substrate, the basic characters of which are systematically studied and compared with some other commonly used diamond films. Besides, the growth times for three respective layers are accordingly determined. It is further clarified that the underlying boron-doped micro-crystalline diamond layer can well adhere to the WC–Co substrate due to either the reduction in the residual stress or the formation of B–Co compounds. There is no doubt that the surface undoped nano-crystalline diamond layer with relatively lower hardness and initial surface roughness is more convenient to be polished to the required surface roughness. Moreover, when the growth times for the middle undoped micro-crystalline diamond layer and the surface undoped nano-crystalline diamond layer are both appropriate, the undoped micro-crystalline diamond layer with extremely high diamond quality and hardness can effectively reinforce the surface hardness of the whole composite film. Based on the discussions on the influences of the growth times for the different layers on the performance of the composite diamond film, the growth times for the boron-doped micro-crystalline diamond, undoped micro-crystalline diamond and undoped nano-crystalline diamond layers are, respectively, determined as 4, 4 and 2 h. Under such conditions, the reinforcement effect of the middle layer on the surface hardness can be guaranteed, and the undoped nano-crystalline diamond grains have totally covered the undoped micro-crystalline diamond layer.

Abstract:
The rough surface of nano-crystalline diamond spheres induces surface electronic states which appear as a broadened pre-peak over approx. 15 eV at the C K-edge energy threshold for carbon in the parallel electron energy loss spectrum (PEELS). This appears to be at least partially due to 1s-π* transitions, although typically the latter occupy a range of only 4 eV for the sp2 edge of highly-oriented pyrollytic graphite (HOPG). No π* electrons appear in the conduction band inside the diamond particles, where all electrons are sp3 hybridized. PEELS data were also obtained from a chemical vapour deposited diamond film (CVDF) and gem-quality diamond for comparison with the spectra of nano-diamonds. The density of sp2 and sp3 states on the surface of diamond nano-crystals is calculated for simple structural models of the diamond balls, including some conjecture about surface structures. The results are used to interpret the sp2/sp3 ratios measured from the PEELS spectra recorded as scans across the particles. Surface roughness at the atomic scale was also examined using high-resolution transmission electron microscopy (HRTEM) and electron nano-diffraction patterns were used to confirm the crystal structures.

Abstract:
Boron-doped diamonds were deposited by microwave plasma chemical vapor deposition (MPCVD) method in order to investigate the influence of inlet boron concentration on the film properties. The substrate material of the specimens was pure titanium (99.9 %). Boron source was introduced into the vacuum chamber by bubbling of B2O3, acetone and methanol mixture. Samples were produced with different B2O3 concentrations in mixture (1000 ppm, 5000 ppm, and 10000 ppm). The surface morphology of the samples was observed by scanning electron microscope (SEM). X-ray diffraction was used to identify crystal structures of the films. Secondary ion mass spectroscopy was used to examine the qualitative boron contents in the films. For low B2O3 concentrations in liquid mixture (1000 ppm), the surface morphology of the film showed both micro crystalline diamond and nano crystalline diamond. For medium B2O3 concentrations in liquid mixture (5000 ppm), the surface morphology of the film was also consisted of micro crystalline diamond and nano crystalline diamond. However, the content of micro crystalline diamond decreased in comparison with low B2O3 concentration. For high B2O3 concentration in liquid mixture (10000 ppm), the surface morphology of the film was almost dominated by nano crystalline diamond. Therefore, the crystal size of boron doped diamond decreased with increasing boron concentration. From these results, it appears that boron will restrain the growth of diamond crystal during deposition.

Abstract:
In this study, the tribological properties of the monolayer micro-crystalline diamond and nano-crystalline diamond films, TiN/diamond and TiAlN/diamond bilayer films on cemented tungsten carbide substrates are evaluated by dry sliding against the medium carbon steel counterpart balls, in terms of the coefficient of friction, wear rate, worn surfaces, and chemical transitions in the contacting wear zones. The significant coefficient of friction reducing effect of top-layer TiN and TiAlN coating only happens on the nano-crystalline diamond film, where the stable coefficient of friction of TiN/nano-crystalline diamond or TiAlN/nano-crystalline diamond bilayer coating reduces 9% or 53% compared with the nano-crystalline diamond film. The formed ionic metal oxides such as Fe2O3 or Fe3O4 coming from the chemisorbing of the atmospheric molecular water, oxygen in the air and the delamination of steel ball due to the repeated friction interaction is supposed to be responsible for the coefficient decreasing effect. The TiN or TiAlN film on diamond layer exhibits lower positive wear rate compared with the TiN or TiAlN film itself, due to the load support ability improvement resulted from the high hardness of diamond interlayers. Among all the tested hard films, the TiAlN/nano-crystalline diamond bilayer coating exhibits the valid potential to be the optimized tool coating in carbon steel machining in terms of its low coefficient of friction and wear rate, which may come from the self-lubricated transfer tribolayer formation on the TiAlN layer, as well as the enhanced mechanical supporting capacity of the underneath smooth and hard nano-crystalline diamond interlayer.

This is a comparative experimental study of the micro, nanoand ultranano-crystalline diamond deposition. The Hot Filament Chemical Vapor Deposition (HFCVD) reactor deposits the films using different deposition parameters. Scanning Electron Microscopy and Field Emission Scanning Electron Microscopy let morphology inspection. Visible-Raman scattering loaded to estimating relative induced stress, by the graphite peak shift and associated with the defect incorporation and sp2bond enhancement. The x-ray diffraction confirmed the diamond crystallinity, where Scherrer ́s equations estimate crystallite size and diamond renucleation rates. In this work we propose a defect increasing relative graphite incorporation with the transition of micro, nanoto ultranano-crystalline diamond deposition. Besides this, we propose that this increase defects follows the increase diamond renucleation rates and decreases in the induced stress films. Included is a discussion of the possible reasons for these observations.

Abstract:
With the continuing trend towards miniaturization, micro milling plays an increasingly important role in fabrication of freeform and high-accuracy micro parts or components directly and cost-effectively. The technology is in kinematics scaled down from the conventional milling, however, existing knowledge and experiences are limited and comprehensive studies on the micro tooling performance are essential and much needed particularly for the process planning and optimization. The cutting performance of micro tools is largely dependent on the dynamic performance of machine tools, tooling characteristics, work material properties and process conditions, and the latter three aspects will be focused in the study. The state of the art of micro milling technology with respect to the tooling performance has been critically reviewed, together with modelling work for performance prediction as well as metrology and instrumentation for the performance characterization. A novel 3D finite element method taking into account the geometry of a micro tool, including the tool diameter, rake angle, relief angle, cutting edge radius and helix angle, has been proposed for modelling and simulation of the micro milling process. Validation through well-designed micro milling trials demonstrates that the approach is capable of characterizing the milling process effectively. With the support of FEM simulation developed, the tooling geometrical effects, including those from helix angle, rake angle and cutting edge radius with influences on cutting forces, tool stresses, tool temperatures, milling chip formation and temperatures have been comprehensively studied and compared for potential micro tool design and optimization purposes. In an effort to prolong the tool life and enhance the tooling efficiency, DLC and NCD coatings have been deposited on micro end mills by PE-CVD and HF-CVD processes respectively. Corresponding cutting performance of these coated tools have been assessed and compared with those of WC micro tools in both dry and wet cutting conditions so as for better understanding of the coating influence on micro tools. Furthermore, the cutting characteristics of the DLC coated and uncoated tools have been analysed through verified plane-strain simulations. The effects of coating friction coefficient, coating thickness and UCT have been determined and evaluated by design of simulation method. Mechanical, chemical and physical properties of a work material have a direct influence on its micro-machinability. Five most common engineering materials including Al 6061-T6, C101, AISI 1045, 304 and P20, have been experimentally investigated and their micro milling behaviours in terms of the cutting forces, tool wear, surface roughness, and micro-burr formation have been compared and characterized. Feed rate, cutting speed and axial depth of cut constitute the complete set of process variables and they have significant effects on the tooling performance. Fundamental understanding of their influences is essential for production engineers to determine optimum cutting parameters so as to achieve the maximum extension of the tool life. 3D FE-based simulations have been carried out to predict the process variable effects on the cutting forces, tool stresses, tool temperatures as well as micro milling chip formation and temperatures. Furthermore, experimental approach has been adopted for the surface roughness characterization. Suggestions on selecting practical cutting variables have been provided in light of the results obtained. Conclusions with respect to the holistic investigation on the tooling performance in micro milling have been drawn based on the research objectives achieved. Recommendations for future work have been pointed out particularly for further future research in the research area.

Abstract:
Current strategies for designing biomaterials involve creating materials and interfaces that interact with biomolecules, cells and tissues.  This thesis aims to investigate several bioactive surfaces, such as nanocrystalline diamond (NCD), hydroxyapatite (HA) and single crystalline titanium dioxide, in terms of material synthesis, surface functionalization and characterization. Although cochlear implants (CIs) have been proven to be clinically successful, the efficiency of these implants still needs to be improved. A CI typically only has 12-20 electrodes while the ear has approximately 3400 inner hair cells. A type of micro-textured NCD surface that consists of micrometre-sized nail-head-shaped pillars was fabricated. Auditory neurons showed a strong affinity for the surface of the NCD pillars, and the technique could be used for neural guidance and to increase the number of stimulation points, leading to CIs with improved performance. Typical transparent ceramics are fabricated using pressure-assisted sintering techniques. However, the development of a simple energy-efficient production method remains a challenge. A simple approach to fabricating translucent nano-ceramics was developed by controlling the morphology of the starting ceramic particles. Translucent nano-ceramics, including HA and strontium substituted HA, could be produced via a simple filtration process followed by pressure-less sintering. Furthermore, the application of such materials as a window material was investigated. The results show that MC3T3 cells could be observed through the translucent HA ceramic for up to 7 days. The living fluorescent staining confirmed that the MC3T3 cells were visible throughout the culture period. Single crystalline rutile possesses in vitro bioactivity, and the crystalline direction affects HA formation. The HA growth on (001), (100) and (110) faces was investigated in a simulated body fluid in the presence of fibronectin (FN) via two different processes. The HA layers on each face were analysed using different characterization techniques, revealing that the interfacial energies could be altered by the pre-adsorbed FN, which influenced HA formation. In summary, micro textured NCD, and translucent HA and FN functionalized single crystalline rutile, and their interactions with cells and biomimetic HA were studied. The results showed that controlled surface properties are important for enhancing a material’s biological performance.

The objective of this project is to understand the details of the electronic transport in low dimensional carbon structures at low temperatures as well as high magnetic fields. The emphasis is on the quasi-2 dimensional thin grain boundary regions of nanodiamond films and one dimensional carbon nanotubes. As such nitrogen “doped” and undoped nanodiamond films were synthesized by the hot filament chemical vapor deposition method (HFCVD). The films were micro-structurally and electrically characterized using several techniques such as Raman spectroscopy, scanning electron microscopy, transmission electron microscopy, atomic force microscopy and magnetoresistance (MR) measurements. The electronic transport properties were compared to the films deposited by microwave plasma enhanced chemical vapour deposition (MWCVD). The conductivity revealed a typical semiconducting and semi-metallic behavior for the HFCVD films depending on the nitrogen percentage in the chamber. The dephasing time of the electronic wave function was found to be weakly temperature dependant i.e. τ T-p with p < 1, a behavior reported in artificial superlattices. These results show potential application of these materials in novel nano-electronic devices. Previously the transport mechanism in nanodiamond films has been attributed to hopping conduction in the grain boundaries which is predominately disordered sp2 phases. Our studies on nanodiamond films have however shown different mechanisms in these films. We observed very little contribution from hopping and pronounced weak localization contributions in nanodiamond films. We thus establish the significance of tunneling transport in nanodiamond films. We also studied the electronic transport in films of metal filled multiwalled carbon nanotubes which show significant contribution from the hopping mechanism and a negative magnetoresistance at low fields that crosses over into positive MR at high magnetic fields.

In this dissertation, the different array interval structure of nanocrystalline diamond (NCD) films were fabricated to study the effect on the field emission properties and gas ionization sensors on different pressure in nitrogen gas, respectively. NCD films were deposited on silicon substrate by microwave plasma chemical vapor deposition system. The surface morphology of NCD films were characterized by the field emission scanning electron microscopy. The characterization of NCD films were analyzed by Raman, XPS and AFM to show the quality, the surface composition and average roughness of nanocrystalline diamond, respectively. The array structures were fabricated by photolithography technique with the interval of 100 , 500 and 1000μm, respectively.. Field emission properties were measured with anode voltage from 0 to 1100 V. It is found that the turn on electric field were improved from 14.67 V/μm to 8.5 V/μm when the array structure interval was increased from 100μm to 1000μm. It is indicated that the field emission properties were improved with the array interval increased. The arrayed nano-crystalline diamond devices of gas ionization sensors were performed using N2 gas with the array interval of 100, 500 and 1000μm, respectively. However, it was found that the breakdown voltage decreased with the array interval decreased.

Diamond films possess excellent physical, chemical, and mechanical properties, such that the syntheses of diamond films have been the focus of research. Moreover, the diamond films own marvelous field emission properties and have great patential for the application on the electron field emission devices. The chemical vapor deposition (CVD) has been the most widely utilized process for growing the diamond films. In this study, we used microwave plasma enhanced chemical vapor deposition (MPECVD) technique to synthesize microcrystalline diamond/ultrananocrystalline diamond (MCD/UNCD) composite films, for the purpose of investigating the growth mechanism and the related microstructural characteristics of the MCD/UNCD composite films. We first grow ultrananocrystalline diamond (UNCD) thin films as nucleation layers, followed by a secondary MPECVD process for growing microcrystalline diamond (MCD) thin films. We used Raman spectroscopy, field emission scanning electron microscopy (FESEM), optical emission spectroscopy (OES), and transmission electron microscopy (TEM) to characterize the MCD/UNCD thin films. The growth mechanism was discussed based on these investigations. In the first part of research, different proportion of argon (0-90 %) was added into CH4/H2 plasma for the deposition of the secondary MCD layer. Among them, the 50% Ar plasma results in the best electron field emission properties, that is, the turn-on field of 6.50 V/μm for (MCD50)1h/UNCD1h and of 5.0 V/μm for (MCD50)1h/UNCD3h films. TEM examinations indicated that the two step MPECVD process markedly modified the gannular structure of UNCD films, resulting in large-grain/small-grain duplex microstructure. In the second part of research, we changed the deposition time for growing the MCD layer (with 50% Ar plasma). We observe that 1 h deposition of MCD layer leads to the best electron field emission properties. The best electron field emission properties obtainable are：turn-on field of 5.0 V/μm with EFE current density of 0.70 mA/cm2 at an applied field of 27.5 V/μm.

Diamond film has attracted immense attention as a field emission material due to its negative electron affinity and robust mechanical and chemical properties. It has been widely investigated. Based on literatures, the critical factors of diamond film field emission are grain size, the structure of grain boundary, conductivity, graphite structure distribution, structural defect density, surface roughness, surface functional groups, etc. In this work, nano-graphite fiber embedded nano-crystalline diamond films were synthesized, and it’s excellent electron field emission properties were studied. The nano-graphite fiber embedded nano-crystalline diamond film can be turned on at a low field as 4.4 V/μm and attain large field emission current density about 0.06 mA/cm2 at 7 V/μm applied field. The embedment of nano-graphite increased the conductivity of the film, and lowered the work function of nano-crystalline diamond film. The defects in the diamond structure created additional energy levels in the diamond band structure, which induced electron emission at low electric fields. The morphology and surface roughness of carbon embedded nano-crystalline diamond films were studied by field emission scanning electron microscope (FESEM) and AFM. Raman, XPS, XRD, TEM, CL are used to investigate the microstructure of the films. Conductivity and field emission properties were measured by four point probe and homemade field emission system respectively. In the future, the parameters of MPECVD grown nano-crystalline diamond film were further optimized to get better field emission cold cathode materials.

In this dissertation, Nano/Micro crystalline diamond were fabricated on different silicon-based structures to study the effect on the field emission properties. NCD and MCD were deposited on Planar-Si, Pyramid-Si and SiNWs/Pyramid-Si by microwave plasma chemical vapor deposition system. The surface morphologies of diamond were characterized by the field emission scanning electron microscopy. The characterizations of diamond were analyzed by Raman, XPS and AFM to show the quality, the sp3/sp2 ratio and average roughness of diamond, respectively. It is found that the turn on electric field of NCD/SiNWs/Pyramid-Si field emission cathode is lower (3.11 V/μm) through ultrasonication pretreatment than other structures such as NCD/Planar-Si (4.8 V/μm) and NCD/Pyramid-Si (4.35 V/μm). And the lower turn on electric field NCD/SiNWs/Pyramid-Si (3.2 V/μm) through rub and ultrasonication pretreatments than other structure such as NCD/Pyramid-Si (3.9 V/μm). While using C10H16 and ethylene glycol as seeds layer to deposite MCD on Planar-Si and Pyramid structures, the turn on field improved from 3.86 V/μm of MCD/Planar-Si to 3.15 V/μm of MCD/Pyramid-Si. And 4.5 V/μm of MCD/Planar-Si to 2.9 V/μm of MCD/Pyramid-Si by using C10H16 and diethylene glycol as seeds layer. Keyword: NCD, SiNWs, Pyramid

We have performed x-ray absorption near edge structure (XANES) study on Cu ion implanted, fluence varies from 1x1015 to 1x1017 ions/cm2, ultra-nano crystalline diamond (UNCD) films. From the XANES of C K-edge of the films, we found that the absorption intensity of sp3 structure decreased tremendously. In the meantime, the exciton peak and the second band gap are completely disappeared. We also observed the absorption intensities due to sp2 structure, C-OH bond, C-H bond and the surface defect peaks all increase. As the Cu-ion fluence reached 1x1016 ions/cm2, the absorption intensity of sp2 peak decreases, the intensities of C-H bond and the surface defect peaks increase. When the Cu-ion fluence reached 5x1016 ions/cm2, the sp2 peak shifts to lower energy, which may be related to the formation of amorphous carbon. Also the intensity of C-OH peak increases, and the intensities of C-H and the surface defect peaks decrease at fluence of 5x1016 ions/cm2. From the spectra of Cu K-edge, the intensity of the main peak, due to Cu 1s to 4p transition, decreases as the Cu-ion fluence increases. From Cu L2,3-edge we found an obvious broadening of the main absorption peaks at the highest fluence. When the fluence increases, sp3 structure decreases and sp2 structure increases. While the fluence exceeds 5x1016 ions/cm2, sp2 structure decreases and the amorphous carbon forms. At the highest fluence, Cu 3d-4s-4p hybridization increases.

Abstract:
The potential use of coal as source of carbon nano structure is seldom investigated. Herein we report a facile fungal solubilization method to extract mixed phase carbon structure from low grade coal. Coal had been used as a primary source for the production of carbon nanostructure with novel property, in addition to its main utility as a fuel. The major hurdle in its application is the inherent mineral embedded in it. An environmentally benign demineralization procedure make coal as a widely accepted precursor for the novel carbon materials. With Aspergiilus niger leaching, the randomly oriented preformed crystalline mixed phase nanocarbon in coal can be extracted. Raman studies revealed the presence of E2g scattering mode of graphite. The sp3 domains at ~1355 cm-1 (D band) is an indication of diamond like structure with disorder or defect. In the 2D region, multilayer stacking of graphene layers is noticed. The ratio of the defect to graphitic bands was found to be decreasing with increasing rank of coal. Bio leaching of coal enhances the carbon content in coal while eliminating the associated minerals in it. These defected carbon is an ideal material for graphene quantum dots and carbon dots, which are useful in drug delivery and bio imaging applications.
