for the lower and larger undercooling, and plastic deformation and fracture for the medium undercooling. Key words: Ni-Pb monotectic alloy; high undercooling; wear rate; wear mechanism CLC number: TG115.5...Tribological property and wear mechanism of undercooled Ni-Pb monotectic alloys XIE Hui(谢 辉)1, YANG Gen-cang(杨根仓)1, HAO Wei-xin(郝维新)1, LA Pei-qing(喇培清)2, LIU Wei-min(刘维民)2, XU Li-jun(许丽君)1......
. In the severe wear region, the wear rate of MZA is 10-5mm3/m and the dominant wear mechanism in this region is brittle fracture. Key words: mullite/ZrO2/Al2O3; friction and wear; ceramics; wear mechanism CLC... and the testing conditions. The wear mechanism diagram of MZA is constructed, it contains two typical regions. It suggests that the wear mechanisms of MZA in each of the region change from one......

Ahmadi2,B.Niroumand1 (1.Isfahan University of Technology, Department of materials engineering, Isfahan, Iran;2.Merat poolad engineering company, Isfahan, Iran) 摘要:The aim of this investigation was the determination of the predominant wear mechanism on three......
adhesion, plastic forming to fatigue fracture in turn. Key words: MoSi2; tribological property; wear mechanism wear-resistance under 50 N. Fig.2 Variation of friction coefficient with load Fig.3 Variation of wear rate with time Fig.4 Variation of wear rate with load 3.2 Wear mechanism......
resistance and wear mechanism of the hardfacing layer were studied.The experimental results indicate that the hardfacing technology has much more advantages and cheaper than that of traditional... layers were carried out by using two different electrodes. The wear resistance of new electrode hardfacing layer is higher than that of normal hardfacing electrode D322. The wear mechanism of hardfacing......
strengthened by YT758/CuZnNi is approximately 2-3 times higher than that strengthened by YG8/CuZnNi. Key words: wear properties; hardmetal; hardfacing materials; CuZnNi alloy; milling tools CLC number: TG455...Microstructure and wear properties of YT758/CuZnNi hardfacing materials WANG Xin-hong(王新洪)1, ZHANG Min(张 敏)2, ZOU Zeng-da(邹增大)1, QU Shi-yao(曲仕尧)1 (1.

with the increase of normal load in the mixed and gross slip regime, but the normal load has no obvious effect on the wear volume in the partial slip regime. The predominant fretting wear mechanism of magnesium alloy in the slip regime is the oxidation wear, delaminated wear and abrasive wear. Key words: AZ91D magnesium alloy; fretting; friction coefficient; wear mechanism; wear behavior 1......
