...Xin Pei; Wanyou Yang; Shuang Liu; Haotian Guo; Qinghua Zhou Transverse isotropy, a typical property of coating providing protection or lubrication for transmission parts, is different from isotropy focused in most of previous research, catching increasing attention in recent years. This study aims...

...Gongjun Cui; Fangzhou Li; Canxing Bian; Guijun Gao; Ziming Kou The high-temperature wear resistant CoCr matrix coatings reinforced by the Nb element were fabricated on the Inconel 718 alloy by using the hot-pressed sintered method. The effects of Nb on the microstructure, hardness, and high...

...X. H. Wang; S. S. Liu; G. L. Zhao; M. Zhang In situ TiN ceramic particle reinforced FeCoNiCrMnTi high entropy alloy coating was fabricated by laser cladding processing at high purity nitrogen gas atmosphere on the AISI 304 stainless steel substrate. The effect of Ti addition on the microstructure...

...Neha Singh; Sujeet K. Sinha Epoxy with ultra-high molecular weight polyethylene (UHMWPE) and MoS 2 fillers was coated on a bearing steel (SAE 52100). Frictional and wear properties of the coated samples in sliding contact were investigated on a pin-on-disc tribometer under a normal load of 10 N...

...Zhan-jiang Wang; Wen-zhong Wang; Fan-ming Meng; Jia-xu Wang A numerical approach for solving the fretting contact on coated or layered materials, with consideration of loading history, is presented in the paper. The fretting problem was solved by using a semi-analytical method (SAM), in which...

...Xinhong Wang; Min Zhang; Shiyao Qu (Ti,Mo)C multiple carbide reinforced Fe-based composite coating was produced by laser melting a precursor mixture graphite, ferrotitanium (Fe–Ti), and ferromolybdenum (Fe–Mo) powders. The results showed that flowerlike and cubic type (Ti,Mo)C multiple carbides...

...Zhan-Jiang Wang; Wen-Zhong Wang; Hui Wang; Dong Zhu; Yuan-Zhong Hu An elastic contact model for three-dimensional layered or coated materials under coupled normal and tangential loads, with consideration of partial slip effects, has been developed in this paper. The response functions...

...Yuchuan Liu; Q. Jane Wang; Dong Zhu Coatings are widely used for interface performance enhancement and component life improvement, as well as for corrosion prevention and surface decoration. More and more mechanical components, especially those working under severe conditions, are coated with stiff...

... is fully accounted for, as are the interactions between the mechanical and thermal displacements. Some results are presented to illustrate the potential importance of a full thermomechanical analysis as compared to a purely mechanical one as well as to demonstrate the influence of coating properties...

...Yuchuan Liu; W. Wayne Chen; Dong Zhu; Shuangbiao Liu; Q. Jane Wang An elastohydrodynamic lubrication (EHL) model for coated surfaces in point contacts has been developed by combining the elastic deformation formulation for the coated surfaces with an EHL model. Inverse fast Fourier transform (IFFT...

... chromium compounds coating wear debris simulated body fluid friction Metals are widely used in high load bearing and tribological applications due to their superior mechanical properties. Chromium is added as an alloying element to various metals to improve their corrosion resistance...

... ™ ) were applied on the Si 3 N 4 probe. A comprehensive investigation of adhesion, friction, and wear of the uncoated/coated tips in both ambient air and various humidity levels as well as the influence of the coatings on the image resolution was performed. Experiments show that the coatings reduce...

... performed where this effect was investigated in bearings with metal mixed amorphous carbon, Me-C: H, coated rollers that were tested against bearings with standard rollers. The experimental results show that while the bearings with standard rollers can fail due to wear, the bearings with coated rollers...
