本文介绍了用气体碳氮硼三元共渗处理高速钢令的研究工作,试验表明此工艺比现厂用盐浴氰化处理的高速钢令,具有质量好、成本低、无毒性等优点。经2700小时装机试验结果是,用试验工艺处理的高速钢令,不用修磨即可继续使用的占95％,而盐浴氰化的只有50％。初步认为,高速钢令的表层组织为马氏体和一定量的残余奥氏体,对提高高速铜令的使用性能有较好的效果。 In this paper, the research work of gas carbonitriding boron ternary system for treating high speed steel is introduced. The experiment shows that the process has the advantages of high quality, low cost and non-toxicity compared with the high speed steel with cyanidation by salt bath in the factory. After 2700 hours of installation test results, the high-speed steel with the test process, no grinding can continue to use 95%, while salt bath cyanide only 50%. It is preliminarily believed that the high-speed steel makes the surface structure of martensite and a certain amount of retained austenite, which has good effect on improving the service performance of high-speed copper.
