Significant reduction in friction and wear of a high-entropy alloy via the formation of self-organized nanolayered structureLu Yang1,Zhuo Cheng1,Weiwei Zhu1,2,Cancan Zhao1,Fuzeng Ren11. Department... HEA matrix with low SFE and uniformly dispersed Ag precipitates.In comparison with CoCrFeNi,a significant reduction in friction and wear was found in (CoCrFeNi)90Ag10HEA through the spontaneous......
compared with Cu-Gr composites with the same volume fraction of GNSs and Gr. Moreover, the friction coefficients and wear rates reduce significantly by the addition of GNSs, whereas the limited impact on reducing friction and wear is found on graphite. The abrasive and delamination wear are the dominant wear mechanisms of the composites. It is believed that the superior mechanical......

Effect of Cold Deformation on the Friction–Wear Property of a Biomedical Nickel-Free High-Nitrogen Stainless SteelHao-Chuan Zhao1,2,Yi-Bin Ren2,Jia-Hui Dong2,Xin-Min Fan1,Ke Yang21. Department...,mechanical and corrosion properties of different cold-rolled biomedical nickel-free highnitrogen stainless steels(NFHNSSs) were investigated to study the effect of cold deformation on its dry wear......
-disk wear instrument. For Ti-Nb alloys, Ti-10Nb alloy shows a smallest steady friction coefficient, Ti-5Nb alloy shows the smallest wear depth and best wear resistance, and Ti-15Nb alloy shows.... The experimental parameters were estimated as follows: dry condition, normal load 2 N, test-disk rate 100 r/min and test-disk wear radius 3.5 mm. Friction coefficients were automatically recorded......
and maintaining time was 60 s. Dry sliding wear tests were operated using a pin-on-disc type wear apparatus MM2000. In this system, the specimen size was φd6 mm×12 mm, the friction disc kept rotating... has lubricious effect and descends the extent of the friction. Finally, the presence of graphite film decreases the wear loss of the composite. So the wear mechanism of the composite with the 240 μm......
