The results show that the dispersive oxide and metallic elements influence the composition, thickness and hardness of friction film. Thus, the coefficient of friction (CF) of specimens is influenced. Specimens with dispersion strengthening Al2O3-Cu matrix display stable coefficient of friction and higher wear than other specimens. The absence of mechanical hybrid deformation layer in specimen of Fe-Co-Cu matrix lead to the friction occurred between the oxide film and the mating plate, which provides well wear resistance.      ZTFLH:  TF125   服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 王晔 燕青芝 张肖路 葛昌纯 赵海芹 44.8K 链接本文: https://www.cjmr.org/CN/      或      https://www.cjmr.org/CN/Y2013/V27/I1/37 1 A.
