摘要
我们已研制成功的"快速渗氮新工艺"是针对渗氮专用钢38CrMoAlA 进行的。而38CrMoAlA 钢冶炼困难,价格昂贵,加工与热处理工艺性能较差,渗层脆性大等缺点,已有工厂寻求在某些零件上用其它合金钢取代。为此我们在相同快速渗氮工艺条件下,研究了不同成分的钢对渗速、显微组织和性能的影响;分析了合金元素在快速渗氮中的作用;得到了一些有价值的结论,为推广快速渗氮工艺于其它钢种奠定了一定的基础。
The new fast nitriding process is successfully developed by us for nitriding steel38CrMoAl.Howevr,the 38CrMoAl steel is difficult to be smelt,poor in the proper-ties of machining and heat treating process,expensive in price and brittle in thecase.This steel is substituted by other alloy steels for making the spare partsin some factories.For this reason,the effect of the alloy elements on thenitridingspeed,structure and properties of the steels with different compositionwere studied,and worthy conclusions were obtained.All of these lay afundatio not wide-spreading the fast nitriding for other steels.
