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......
