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表面硬化钢和钛合金的烧伤理。

The distribution as well as the content of the particles in N-P electroless codeposits is determined by means of conventional stereome-tric metallograph.

介绍用普通的体视金相法,容易地测定化学复合镀层中固体微粒的分布形态及其含量。
