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

表面包含一个度、耐磨性的壳韧性的芯。

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

使渗碳,碳:使与碳一起处理,使与碳混合或使充满碳,如的表面粹火.

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金相显微分析等技术研究了表面和钛合金的烧伤机理。
