一、前言用表面化学热处理的方法提高高速钢刀具的耐用度,效果显著,因此在国内外受到广泛的重视。自1975年以来,我们在分析目前高速钢刀具各种表面强化工艺优缺点的基础上,结合我厂的具体条件,试验了一种用于高速钢刀具的滴注式气体多元共渗新工艺。经过二年多的生产实践证明:高速钢刀具经气体多元共渗 First, the preface Surface chemical heat treatment method to improve the durability of high-speed steel cutting tools, the effect is significant, so at home and abroad by a wide range of attention. Since 1975, based on the analysis of the merits and demerits of various surface hardening processes of high speed steel tools and the specific conditions of our factory, we have tested a new technology for dripped gas multicomponent permeation for high speed steel cutting tools. After more than two years of production practice has proved that: high-speed steel cutting tools by gas multiple infiltration
