一、引言 已经证实,氮离子注入Co-WC可以改善磨损性能,这意味着越来越多的工具和部件可使用这种工艺进行处理。 为了检验和评价注入效果,仅仅用实验室的磨损试验是不够的,因为这种试验重复性较 I. INTRODUCTION Nitrogen ion implantation into Co-WC has been shown to improve wear properties, which means that more and more tools and components can be processed using this process. In order to test and evaluate the effect of injection, it is not enough to use only the laboratory wear test, because this test is more reproducible
