机器零件中40～50％需要渗碳或碳氮共渗,5％左右需要氮化或软氮化。70年代离子氮化问世后,很快获得工业上的广泛应用。80年代已发展成为汇集多种学科、多项技术的新兴边缘学科—等离子轰击化学热处理。目前各国正竞相开发研究。浙大材料系和校机械厂研制的多功能离子轰击炉,能进行离子氮化、离子软氮化、离子渗碳、离子碳氮共渗,而且能耗低(节能50％),渗速快,质量好,无污染,经济效益高。
40-50% of machine parts require carburizing or carbonitriding, and about 5% require nitriding or nitrocarburizing. After the advent of ion nitriding in the 1970s, it was rapidly gaining widespread industrial use. 80 years has developed into a collection of many disciplines, a number of emerging technologies edge discipline - plasma bombardment chemical heat treatment. At present, all countries are competing to develop research. Zhejiang University Department of Materials and Machinery Factory developed a multi-functional ion bombardment furnace, capable of ion nitriding, ion nitrocarburizing, ion carburizing, ion carbonitriding, and low energy consumption (50% energy saving), fast infiltration, Good quality, pollution-free, high economic efficiency.
