表面硬化的

Casehardening involves a change of surface properties to produce ahard,wear-resistant shell about a tough,fracture-resistant core.

化包含一个度、耐磨的壳以及的芯。

"carburize:To treat, combine, or impregnate with carbon, as when casehardening steel."

使渗碳,碳化:使与碳一起处理,使与碳混合或使充满碳,如钢的粹火化.

In this paper,the mechanism of workpiece burn during grinding of casehardened steel and titanium alloys was studied by the use of SEM,EPMA,XPS and the metallograph analysis.

本文应用SEM,EPMA、XPS及金相显微分析等技术研究了化钢和钛合金的烧伤机理。
