的摩擦因数更低,抗磨损能力更强. 关键词:WS2；MoS2；C；摩擦性能；磨损性能 中图分类号:TQ174; TH117.3 文献标识码:A Tribological and wear properties of reaction-sputtered WS2/MoS2/C composite films ZHOU Lei1, YIN... compact microstructures with lower friction coefficients and better wear resistances than pure MoS2 film under humid atmospheric conditions at room temperature, and their hardness is nearly increased......
condition, friction coefficient and wear loss of LY12 aluminum alloy were measured in sliding against samples of 16Mn treated by cubrizing and sulphiding respectively; In order to avoid the transfer of aluminum to the steel that lead to the inaccurate measurement of wear loss of carburized samples, Gr15 steel was adopted as counterpart face to measure the wear loss of them. SEM and EDAX were used......
Trans. Nonferrous Met. Soc. China 22(2012) 1918-1923 Dry sliding wear behavior of cast Mg-11Y-5Gd-2Zn magnesium alloy HU Mao-liang1, 2, WANG Qu-dong1, LI Cheng1, DING Wen-jiang1 1. National..., Harbin 150040, China Received 10 November 2011; accepted 31 May 2012 Abstract: Dry sliding wear tests on as-cast and cast+T6 Mg-11Y-5Gd-2Zn magnesium alloys were performed using a ball-on-plate......
China) 摘要:Mo-base materials have special use in many fields. One of them is to use as substrate materials for dynamic airproof ring. But the hardness and the wear resistance of Mo-base materials are not good for working under the condition of high temperature and high speed. So it must be cover with chromium coating that has high hardness, excellent wear resistance and high credibility. At present......
