According to the working condition of the wear-resistant and heat-resistant parts, it designed the composition of the wear-resistant and heat-resistant steel. Different amount of Ti were added to wear-resistant and heat-resistant steel. The effects of Ti on microstructure, hardness and wear resistance of wear-resistant and heat-resistant steel were researched by microstructure observation, x-ray diffraction，hardness and wear resistance test. The results show that proper amount Ti combines with C to form a certain number particle TiC in the wear-resistant and heat-resistant steel. TiC is dispersively distributed in austenite matrix and improves the hardness and wear resistance of wear-resistant and heat-resistant steel greatly. It has a certain economic benefit.

Aiming at improving the impact wear-resistant performance of metals, a new sort of surfacing electrode named TKCE50 was developed in this paper. This electrode is a Fe-Mn-Cr-Mo-V alloy system and belongs to iron-base wear-resistant materials. Tests like hardness, wear loss and impact-abrasion test were performed on the samples surfaced with the electrode. The results indicated that TKCE50 had not only good welding technological properties, but also super work-hardening effect and perfect impact wear-resistance. In addition, the work-hardening and wear-resistant mechanisms for this electrode were discussed based on corresponding experimental investigation and theoretical analysis.

The development of wear-resistant materials with excellent properties is of great research value in the manufacturing industry. In this paper, a new kind of low-vanadium wear-resistant alloy was designed and characterized to unveil the influence of vanadium content coupling with heat treatment on the microstructure, hardness, and abrasive wear property. The performances of commercial high chromium cast iron (HCCI) and the new low-vanadium wear-resistant alloy are compared. The alloy with 3 wt.% vanadium quenched at 900 °C and tempered at 250 °C, possessing VC, Mo2C, and M7C3 distributed in the martensite matrix, displayed a wear resistance two times better than the HCCI. The results showed that the increase of vanadium content from 0.98 wt.% to 3.00 wt.% resulted in a decrease in the size of M7C3 and a more homogeneous distribution of M7C3. VC with a bimodal distribution is effective for impeding grooving or indenting by abrasives because of their high hardness, which plays a vital role in improving the wear resistance of low-vanadium wear-resistant alloy.

Laser cladding is an effective way to improve the surface hardness and wear resistance of titanium alloy. The powder materials and laser cladding process parameters have great influence on the properties of the wear resistant coating. In order to reduce the common defects including the cracks and pores of the coating, titanium alloy powder and self-melting alloy powder are selected to ensure the good adhesion between titanium alloy and wear resistant coating. In addition, the strengthening phase and self-lubricating phase were added to the laser cladding powder material to improve the micro hardness and reduce the friction coefficient, which bring in the improvement of the wear resistance of the coating. In the present work, the selection principle and application effect of powder materials for wear-resistant coatings are reviewed. the research status of the influence of laser technological parameters on coating properties is discussed. Meanwhile, the methods to reduce the defect of wear resistance coating by laser cladding are proposed.

Nitride-bonded silicon carbide is an alternative to steels resistant to abrasive wear. This paper presents the results of a nitride-bonded silicon carbide (SiC) wear test in diverse soil conditions. The test was performed on a “spinning bowl” test stand on three soil types: loamy sand, light loam and ordinary loam. The results were referred to the wear test for materials used to make parts working soil mass, i.e., abrasive wear-resistant steel, boron steel and C + Cr + Nb padding weld. The abrasive wear resistance of silicon carbide was shown to depend on the grain size distribution of the soil being worked. Silicon carbide showed the highest resistance in light soil. However, the padding weld showed higher wear resistance in the other soil conditions. Nitride-bonded silicon carbide had higher wear resistance than the steels under study in all of the soils. These findings are supplemented by an analysis of the condition of the worked surfaces after friction tests. The dominant wear methods in all abrasive masses were micro-cutting and furrowing.

Wear-resistant casting was made by V-EPC infiltration process. The matrix material was high boron steel casting. Surface composite materials layer was ceramic particles, such as WC, Ferrochromium, and Borax, etc. High boron molten metal was infiltrated into the composite layer and a good cast-infiltration layer may be formed by the interaction of vacuum and high temperature. The wear-resistant casting made with this process has high strength, hardness, and good wear-resistance. It is a new process that wear-resistant casting will be made of.

TiN, TiAlN, CrAlN and TiAlN/TiSiN films were deposited on AISI H13 hot work steel substrate by cathodic arc evaporation method. Each coating was optimized in laboratory conditions and the highest hardness and wear resistance coatings were taken into consideration for this study. Morphological properties, chemical compositions, crystallographic structure, nano hardness and adhesion strength of coatings were analyzed with SEM, AFM, EDS, XRD, nano indentation and scratch resistance tester. Wear experiments were performed using ball-on-disk tribometer against Al2O3 ball of 6[Formula: see text]mm diameter and wear volume of coatings were measured using optical profilometer. Wear experimental results revealed that all coated samples showed higher wear resistance and hardness than uncoated AISI H13 steel substrate. The highest wear and scratch resistances as well as nano hardness were attained for CrAlN coating. TiAlN coating has the lowest scratch resistance and wear resistance. Adhesive wear mechanism was the dominant wear mechanism for CrAlN coatings which is the highest wear resistant coating. Abrasive wear mechanism was the dominant wear mechanism for TiAlN coatings which is the lowest wear resistant coating.

The wear properties of Ti-6Al-4V alloy have drawn great attention in both aerospace and biomedical fields. The present study examines the wear properties of Ti-6Al-4V alloy as prepared by selective laser melting (SLM), electron beam melting (EBM) and conventional forging processes. The SLM and EBM samples show better wear resistance than the forged sample, which correlates to their higher hardness values and weak delamination tendencies. The EBM sample shows a lower wear rate than the SLM sample because of the formation of multiple horizontal cracks in the SLM sample, which results in heavier delamination. The results suggest that additive manufacturing processes offer significantly wear-resistant Ti-6Al-4V specimens in comparison to their counterparts produced by forging.

Among the many different ways to improve the performance of molds for injection molding, there are those that are based on the application of thin multi-layer wear-resistant coatings by cathode-ion bombardment. However, due to the relatively small thickness of the applied coatings, measuring their parameters is a difficult task. Therefore, the article considers methods for determining the main parameters of thin multilayer coatings, such as: microhardness, separation and crack resistance coefficients, Young's modulus. The results of measurements of several coatings of different compositions are presented.

Hardfacing can be broadly defined as the application of a wear-resistant material, in depth, to the vulnerable (or worn) surfaces of a component by a weld overlay or thermal spray process.In the paper are presented the main hard facing iron-base and nonferrous alloys together with their properties and applications, together with a comparison of its performances.In addition, hardfacing alloys are applied to critical wear areas of original equipment or during reclamation of parts. These alloys, which are referred to as buildup alloys, are not designed to resist wear but to return a worn part beck to, or near, its original dimensions and/or to provide adequate support for subsequent layers of more wear-resistant hardfacing alloys.

Implant failure due to aseptic loosening is a major complication in total hip arthroplasty. Different implant coatings aim to reduce the risk of implant loosening by anti-infectious, bio-active or wear resistant approaches. The mechanical properties, especially bonding strength and wear resistance, of a Cu-TiO2, CaP and TiN coating were investigated in this study. A scratch test and a standard adhesive test were used to determine the bonding strength of the coatings. To analyse the wear resistance a modified special testing machine was used to evaluate wear with PU-foam and PMMA as counterparts. The investigations showed that all coatings have greater bonding strengths than the minimum required 22 N/mm2 for medical implant coatings. Significant differences in total wear were determined during the wear tests. With the exception of the CaP no removal of the coatings was detected.

The authors thereof have developed a technology for application of wear-resistant coatings to protect against wear. The research team tested how efficiently powdered material could be heated in a plasma jet. They studied the physical and mechanical properties of coatings by kinetic micro-indentation and tested the plasma sprays for wear resistance. Tribological laboratory tests used the roller-on-roller method. Thus, WC/Co/Cr coatings had the most stable tribological properties and were more wear-resistant, compared to other tested coatings. Cylinder liners of heavy-duty diesel engines were enhanced by this technology. The pilot batch showed promise, as it might triple effectively the service life of diesel engines.

The paper describes the technology of producing a wear resistant silicon nitride coating on cemented carbide cutting tools and factors affecting its structure and thickness. A review of domestic and foreign authors’ works is given on the properties and applications of cemented carbides in cutting, drilling, die stamping tools, wear resistant materials, for chipless processing of wood, plastics. It is noted that one of the promising ways of cutting tool development is using indexable throwaway inserts (ITI) with wear resistant coatings. The choice of silicon nitride as a material for cemented carbide tool coating is justified. The data on silicon nitride deposition methods, investigation of cutting tool structures and properties are provided. Laboratory and factory tests of Si3N4-coated cemented carbide tools demonstrated coating applicability in improving the wear resistance and lifetime of cutting inserts.

This article discusses the influence of the thickness of a nano-structured wear-resistant layer of the Ti–TiN–(Ti,Al,Si)N multilayer composite coating on its mechanical and performance properties. The study was focused on the coatings with the following thicknesses of its wear-resistant layers: 2, 3.5, 5, 7, 11, and 15 μm. The relation between the thickness of a wear-resistant layer and the time of its deposition was investigated, and the effect of the above thickness on hardness and wear resistance in scratch testing was considered. Cutting tests were conducted in turning steel C45 with carbide inserts with the coatings under study at various cutting speeds (vc = 250, 300 and 350 m/min). The study found the value of thickness of wear-resistant layer providing the longest tool life at various cutting speeds. The differences in the nature of wear for the coatings with various thicknesses of wear-resistant layers were considered.

Materials designed for rolling or sliding contact, like corrosion-resistant materials, can provide great cost savings to industry. So why can't such “tribomaterials” be designed based on materials properties that control friction and wear? In recent years, it has become clear that the properties we need to understand are not only those of the starting materials—whether bulk solids or engineered surfaces—but also those of the materials generated within the sliding (or rolling) contact, the so-called “third-body” materials. This article reviews third-body processes and their role in controlling friction and wear of practical surface treatments.It may seem odd that properties like slipperiness and wear resistance can be easily described but are not scientifically understood. We can feel that polytetrafluoroethylene is slippery but know that it is not very wear-resistant because we can scratch it with a fork. We can sense low friction when we rub talcum powder between our fingers but know it cannot lubricate indefinitely because it gets ejected as we rub. Is it contradictory to ask for materials that are both slippery and wear-resistant? Slipperiness is associated with low shear strength whereas wear resistance is modeled on high hardness—that is, high shear strength. Before we can answer this seeming contradiction, it is useful to review some aspects of friction and wear.More than 50 years ago, Bowden and Tabor explained how a low shearstrength film can reduce the friction coefficient between two higher shearstrength materials in sliding contact.

Hardfacing is one of the most useful and economical ways to improve the performance of components submitted to severe wear conditions. In this paper, a new kind of alloy called Fe-Cr-C-Nb/Ti alloy system for wear resistant successfully with the shielded metal arc welding (SMAW) method has been studied. The microstructure and wear resistant of hardfacing alloys reinforced with primary carbides were compared in this study. Meanwhile, the average hardness, the abrasion weight loss and microstructure of deposited metal were systematically studied by optical microscopy, scanning electronic microscopy and energy dispersive spectrum analysis. The results showed that the microstructure of the best optimizing hardfacing layer was the mixed martensite and little retained austenite, and NbC/TiC particles distributing dispersively in the matrix. The amount of low-carbon martensite and high-carbon martensite was identical. The alloy system showed high wear resistance due to the formation of dispersed MC type carbides and good toughness due to the exist of low carbon martensite in the matrix. The hardfacing alloy reinforced with complex carbides was also investigated, the microstructure was analyzed and its hardness and wear resistance were evaluated. In conclusion, the distribution, the chemical composition and the amount of the carbides, as well as the matrix microstructure are all factors to influence the crack resistance, hardness and wear resistance of the hardfacing alloys.

High Cu-Pb-Sn, as the material for bimetallic cylinder block, is widely used in the selection of wear-resistant parts due to its excellent wear reduction, thermal conductivity, fatigue resistance, and strong bearing capacity, such as bearings and bearing bushes, aerospace pump rotor, turbine and guide plate, etc. However, because its wear resistance is not enough to meet the harsh conditions of high temperature, high speed, and heavy load, the research on high wear resistance Cu-Pb-Sn materials has important theoretical significance and application value for the application of bimetallic materials. ZCuPb20Sn5 alloy was taken as the research object to analyze the influence mechanism of its different microstructure and mechanical properties on the friction and wear properties of alloy materials. Friction experiments under two conditions of oil lubrication and dry friction were carried out on the MMW-1A pin-on-disc friction and wear testing machine. The wear resistance and wear mechanism of ZCuPb20Sn5alloy under the action of Cu3P were discussed, and a high wear-resistant Cu-Pb-Sn alloy for bimetal cylinder block was prepared. The results show that with the increase of P content, both the friction coefficient and wear rate decrease, and the wear reduction of ZCuPb20Sn5 alloy increases. Under oil lubrication conditions, the friction coefficient decreases by 21.4% and the wear rate decreases by 85.5% compared with that without adding P. The friction-reducing and wear-resistant properties of ZCuPb20Sn5 alloy materials are increased. In dry friction and oil lubrication, the mass wear amount of ZCuPb20Sn5 alloy material decreases with the increase of P element addition, and the change rule of alloy wear amount is consistent under the two methods. In the process of friction and wear, adhesive wear occurs, and the wear amount of the alloy material increases. With the increase of P content, the lead particles are refined and evenly distributed, which promotes the formation of a uniform self-lubricating lead film during the friction process and reduces the degree of adhesive wear. The appearance of Cu3P reduces the contact area of the friction surface and weakens the adhesive wear, so the wear rate is reduced.

The microstructure, toughness, hardness and wear resistance of Fe-B-C cast wear-resistant alloy were studied. The results indicate that, the as-cast Fe-B-C alloy comprises pearlite, ferrite and eutectic phase Fe2 (B, C), and that, with increasing boron and carbon contents, the boride volume fraction (BVF) and macrohardness increase; furthermore, when boron content increases from about 0.5 wt.% to 2.0 wt.%, the increase trend of the macrohardness will become smaller with increasing the carbon content. The results also indicate that, after heat-treatment, the Fe2 (B, C) becomes coarser than that as cast condition, and the boron content has less effect on the martensite hardness at the same carbon content; with increasing boron and carbon contents, the hardness of the samples increases and inversely the toughness decreases. At a lower BVF, the matrix plays a dominant role on the impact toughness of Fe-B-C alloy; however, at a higher BVF, the BVF plays a dominant role. The wear test results indicate that, with increasing the boron and carbon contents, the weight loss of the samples decreases, namely, the increase of wear resistance.

Mining and processing minerals is one of the priority directions of development the state. Machines parts experience tremendous loads during extraction and processing of soils, this leads to their rapid wear. Several principal ways to increase the wear resistance these materials exist: the creation of coatings (surfacing, laser, plasma treatments), melt doping, the introduction local wear-resistant elements. The introduction wear-resistant inserts into the base metal in places that are subject to the greatest load is the most preferable from the point of view of economic efficiency. The method obtaining local wear-resistant elements based on carbides, their introduction into the gasified casting, as well as the study the structure and properties the materials obtained are described in this article.

This study carried out a novel duplex surface treatment on aluminum alloy base to explore the potential improvement of wear and corrosion resistance. Regular arrayed dimple surface texture (DST) and groove surface texture (GST) were fabricated by using laser processing on 6065 aluminum alloy matrix (6065Al). Electrochemical deposition of Ni and Graphene/Ni coatings on textured surface was then performed in electrolytes with concentrations of 0, 0.5, 1 and 1.5 mg graphene. Surface morphology such as diameter of dimple and width of groove measured by C-PSCN stereo microscope presents addition of graphene helps to refine and homogenize the coating. Corrosion resistant properties of the duplex surface treatment were examined by electrochemical corrosion tests and wear resistant properties were tested by UMT-Tribo Lab friction and wear tester in a dry sliding condition at room temperature. Electrochemical corrosion tests results show that the corrosion resistance of samples is related to the specific surface texture and the dimple texture can improve the electrical corrosion parameters, such as the electrode potential, greatly. Friction and wear tests show that the textured Gr/Ni electroplating coating with the 1.5 mg graphene content has best wear properties under vertical friction and each index, such as the coefficient of friction and wear trace width, are superior to other conditions of samples.

This paper is based on the wear-resistant steel NM360 quenching experiments, simulates the steel plate quenching transient temperature field, and analyses the causes of quenching deformation. According to the experimental analysis, the martensitic phase transformation is the main reason of the wear-resistant steel quenching extremely easily deformation, therefore, how to control the time and stress of martensitic phase transformation of the plate surface is the key factor. Through experiments, we found a quenching process of controlling effectively quenching deformation, and it provides some practical experiences for acquiring the higher mechanical properties of this kind of wear-resisting steel.

Mo wear resistant coatings on TC4 alloy were prepared by glow plasma deposition technique. The coatings were deposited at 850-1050°C for 1-5h. Structure, growth kinetics and tribological properties of the coatings were studied. The results revealed that the coatings were mainly consisted of a Mo outer layer and an interdiffusion zone composed of Mo-containing Ti-based solid solution phase just beneath the outer layer. Rising deposition temperature increased coating growth rate. The hardness of the coatings decreased with rising deposition temperature, which caused coating wear resistance decrease. Wear test demonstrated that the Mo coating wear rate was about 1/30 of the TC4 substrate wear rate under dry friction condition at the load of 98N.

The paper presents the results of the investigation focused on the properties of the Cr,Mo-(Cr,Mo)N-(Cr,Mo,Al)N multilayered composite wear-resistant coating with a nanostructured wear-resistant layer. The nanostructure of the coating was investigated using transmission electron microscopy (TEM), the microhardness was measured, and the chemical composition was found. The cutting properties of a tool with the Cr,Mo-(Cr,Mo)N-(Cr,Mo,Al)N coating were studied during the turning of 09G2S silicon-manganese steel. It has been found that the use of a cutting tool with the Cr,Mo-(Cr,Mo)N-(Cr,Mo,Al)N coating reduces the flank wear rate by 1.65 times compared to an uncoated tool.

Where is the abrasive or gradual removal of materials at solid surfaces? It is caused due to the interaction between the sliding surface by mechanical action. The abrasive wears can be recognised as scratches or grooves. To enhance the wear resistance suitable nanocoating is applied on the material surface for better tribological properties such as hardness and toughness. Wear resistant nanocoating is used to reduce or eradicate wear to extend the lifetime of the EN8 steel. EN8 is unalloyed medium carbon steel with better mechanical properties than mild steel and also readily machinable in any condition. The nanocoating materials such as Al2O3, TiO2, SiC, ZrO2, WS2, Si3N4 etc., are used to reduce wear and to enhance hardness and toughness on mild steel through various nanocoating techniques. This paper deals with selection of suitable nanocoating material through AHP (Analytical hierarchal process) - a multi-criteria decision-making method.
