J. Cent. South Univ. (2020) 27: 311-324 DOI: https://doi.org/10.1007/s11771-020-4297-y Wear map for sliding wear behavior of Cu-15Ni-8Sn alloy against bearing steel under oil-lubricated condition... range of 50-700 N and a sliding speed range of 0.05-2.58 m/s were less than 0.14 and 2.8×10-6 mm3/mm, respectively. Stribeck-like curve and wear map were developed to describe the oil-lubrication......

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......
pair is expected to have excellent transmission performance. Key words: internal gear; sliding ratio; quadratic curve; wear Cite this article as: PENG Shuai, MA Zhi-fei, CHEN Bing-kui, QIN Si-ling, WANG... velocities at contact area. Sliding ratio is one of the key factors that determine the degree of wear under low speed, and is a main noise source. By now, some researches concerning the problem have......
Structure and sliding wear behavior of 321 stainless steel/Al composite coating deposited by high velocity arc spraying technique CHEN Yong-xiong(陈永雄), XU Bin-shi(徐滨士), LIU Yan(刘 燕), LIANG Xiu... different tribological behavior. Under the dry sliding condition, the anti-wear property of 321/Al coating is about 42% lower than that of 321 coating. But under the oil lubricated conditions......
