引言为了提高零件的耐磨性、耐蚀性与疲劳极限,呵以选用各种不同的化学热处理方法。H.Kunst 在1977年举行的第33届热处理学术讨论会上虽作过关于盐浴氮碳共渗后在氧化性介质中冷却方法的报告。当时已经注意到,氮碳共渗后于氧化性盐浴中冷却,除了可以消除废物中的有毒物质外,还能对零件性能产生有利的影响。随后于1981年,又提出采用氧化性介质冷却的盐浴氮碳共渗的新的应用报告,并与化学镀层及电层镀作了对
Introduction In order to improve the wear resistance, corrosion resistance and fatigue limit, Oh choose a variety of different chemical heat treatment methods. H. Kunst at the 33rd Annual Symposium on Heat Treatment held in 1977 made a report on the cooling method in oxidizing media after salt bath nitrocarburizing. At that time, it was noticed that nitrocarburizing followed by cooling in an oxidizing salt bath would have a beneficial effect on part performance in addition to eliminating toxic substances in the waste. Subsequently, in 1981, a new report on the application of salt bath nitrocarburizing using an oxidizing medium was also proposed and compared with electroless and electro-layer plating
