摘要
金属的摩擦磨损是由力学的、物理的、化学的多个作用产生的结果 ,是机械效应、热效应、化学等效应综合作用的过程 .磨屑的形成遵循摩擦时的塑性变形—裂纹萌生—裂纹扩展、断裂形屑的规律 .
Metal friction and abrasion wear are resulted from mechanics, physical and chemical effect.It is a process in which mechanical,heat,chemical effects synthetically take effect.The emergence of frazil follows the princi ple,namely plastic deformation-crazing coppice-crazing expansion-crack.Abrasi on wear is a dynamic process.
