dry sliding process decreases the wear loss. At low load, the wear mechanism of the composite is mainly abrasive wear and oxidation wear; at high load, except that the composite with 20% graphite is still with abrasive wear and oxidation wear, the wear mechanism of other composites changes to delamination wear. Key words: magnesium matrix composite; Ce; graphite; wear resistance ......
substituted into the dynamic model, which was to analyze the dynamic response of the 3RSR parallel mechanism with wear and spherical joint clearance. The simulation results show that the irregular wear... the movement stability of the mechanism. Key words: parallel mechanism; dynamics; spherical joint clearance; wear; Newton-Euler method Cite this article as: HOU Yu-lei, DENG Yun-jiao, ZENG Da-xing. Dynamic......
regression model statistically. Compared with the AZ31B magnesium alloy, the nano-composite shows lower wear rates due to higher hardness improvement caused by the reinforcement. The wear mechanism appears to be a mix-up of ploughing, rows of furrows, delamination and oxidation. Key words: AZ31B magnesium alloy; nano composite; wear mechanism 1 Introduction The alloys and composites of magnesium......

and the subsurface of the composites. The crossover from abrasive wear mechanism to delamination wear mechanism of the composite is related not only with the loads but also with the sliding speeds. Key words: magnesium matrix composite; whisker; wear mechanism; wear rate 金属基复合材料的耐磨性在磨粒磨损和有润滑的情况下优于基体[1?7].SHARMA等[1]指出,AZ91镁合金中引入长石颗粒可以明显改善其耐磨性能.LIM 等[2]研究发现加入Al2O3颗粒能使合金的耐磨性最高提高1.8倍.上述报道在增强相体积分数较低的情况下,增强体......
so the graphite particles can keep intact, which can still work as lubricant. At low load, the wear mechanism is abrasive wear and oxidation wear. At high load, the wear mechanism changes.... The microstructure and wear resistance of the composite are discussed, especially the effect of the additions on the dry sliding wear behavior along with the changes of wear mechanism under different......
