一、引言多年来的使用实践表明,表面为莱氏体组织的凸轮轴具有良好的耐磨性和耐热性。因此,它特别适用于润滑条件较差(如采用激溅润滑方式)的柴油机。本文将要阐述得到莱氏体组织的一种新的热处理方法——表面重熔硬化处理。
I. Introduction The use of practice over the years shows that the surface of the ledeburite camshaft with good wear resistance and heat resistance. Therefore, it is particularly suitable for poor lubrication conditions (such as the use of splash lubrication) diesel engine. In this paper, we will describe a new heat treatment method for obtaining ledeburite-surface reflow hardening.
