本文介绍了国外渗硼工艺、方法、应用、现状及存在的问题。并着重介绍了渗硼的动向,即共晶法、多元共渗法、在电热旋流层中渗硼及辉光离子渗硼等工艺试验和研究成果。 This paper introduces the overseas boronizing technology, methods, applications, status quo and existing problems. The process of boronizing is also introduced emphatically, that is, the eutectic method, multiple co-permeation method, boronizing and glow-ionizing boronizing in electrothermal swirling layer and other technological experiments and research results.
