| 摘 要： | 利用粉末冶金法制备了Al_2O_3颗粒增强铜基复合材料,分析了Al_2O_3含量和转速对复合材料耐磨性能以及摩擦因数的影响。结果表明:复合材料的磨损量随Al_2O_3含量的增加先减小后增大,Al_2O_3体积分数为15%时耐磨性能最好;磨损量以及摩擦因数随着转速的增大先增大后减小,在400 r·min~(-1)时的磨损最严重,摩擦因数最大;磨损主要机制是粘着磨损和磨粒磨损。

| Abstract: | Al_2O_(3p)/Cu composites was prepared by powder metallurgy method.The effects of Al_2O_3 contents and rotating speeds on wear resistance and friction coefficient of the composites were study.The results show that the wear mass decreased and then increased with increase of Al_2O_3 content.The wear resistance was best when volume fraction of Al_2O_3 was 15%.Wear mass and friction coefficient raised and then decreased with increase of rotating speed.The wear was most serious and the friction coefficient was bi... |
