“…The relatively smooth finish may be justified by the relatively homogeneous microstructure of the nanocoating [116] that induces a relatively high incidence of the lubricating mixed W and Co oxides. The lower friction coefficient of the nanocoatings can also be associated with their higher hardness [39].…”

“…The interlocked tungsten carbide particles are observed for sample D. On the one hand, the interlocked nature of tungsten carbide particles provides a significant barrier to the cutting and the degree of the micro-cutting is greatly limited. It is primarily responsible for excellent abrasive wear resistance of composite coatings because it changes the load carrying capacity of the composite structure [5,6]. On the other hand, during the wear process, the wear debris starts to erode the softer matrix and then collides with the hard tungsten carbide particles.…”

“…It has good wear resistance, high temperature stability, corrosion resistance, and good toughness. In order to reduce the overall maintenance costs and improve the wear resistance, it is a well-established fact that wear properties of materials can be improved by reinforcement of a metallic matrix by hard particles [3,[5][6][7][8]. In the present work, the ceramic particle is spherical tungsten carbide.…”

The Ni-based coatings with different content of spherical tungsten carbide were deposited by plasma transfer arc welding (PTAW) method on 304 austenitic stainless steel sheets in this study. The microstructure and wear property of spherical tungsten carbide particle reinforced composite coatings were investigated by means of optical microscope, scanning electron microscope (SEM), X-ray diffraction (XRD), electron probe microanalysis (EPMA) and sliding wear test. It is shown that the fraction of spherical tungsten carbides has an important influence on microstructure of Ni-based overlay. The Ni40 overlay consists of γ-Ni dendrites with interdendritic Ni-based eutectics, borides and carbides improving the wear resistance. In the case of composite coatings with different content of tungsten carbide, many new phases are observed, such as Ni2W4C and NiW. In addition, there are a large number of irregular structures in composite coatings, such as acicular structure and irregular stripe organization. The results of sliding wear test indicate that the mass loss of coatings is influenced by the content of tungsten carbide. The mass loss decreases with the increase of tungsten carbide fraction. At high load, the abrasive resistance of composite coating with 60 wt. % tungsten carbide is improved about 50-fold compared to that of Ni40 overlay. 2015, 5 1985 OPEN ACCESS Metals

“…On the other hand, the surface modification can also make a promising compromise between the cost and the performance of engineering components [ 16 ]. A variety of surface modification technologies have been applied to enhance the tribological performance of Ti6Al4V on the surface by forming coatings/films/layers [ 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 ].…”

Surface texture (ST) has been confirmed as an effective and economical surface treatment technique that can be applied to a great range of materials and presents growing interests in various engineering fields. Ti6Al4V which is the most frequently and successfully used titanium alloy has long been restricted in tribological-related operations due to the shortcomings of low surface hardness, high friction coefficient, and poor abrasive wear resistance. Ti6Al4V has benefited from surface texture-based surface treatments over the last decade. This review begins with a brief introduction, analysis approaches, and processing methods of surface texture. The specific applications of the surface texture-based surface treatments for improving surface performance of Ti6Al4V are thoroughly reviewed from the point of view of tribology and biology.
