摘　　要：在润滑油中添加硫（或磷）的化合物，可以提高其承载能力，防止摩擦面在工作中咬死或卡伤。机理在于使零件摩擦表面形成一层硫化亚铁薄膜，消除了因接触点焊接产生破坏的危险［１］，并能改善零件在磨合期间的抗擦伤性能。硫氮共渗法以渗氮和渗硫同时进行，不但可以赋予零...A new kind of efficient sulfonitriding process has been studied by high frequency induction heating.The agent consists of urea,sodium thiosulffate pentahydrate and KBF 4.Having been treated at a temperature of 570℃ and a time of half an hour,for 38CrMoAl steel,porous layer and nitriding layer with over 0 1mm and with hardness over 1000HV 0.5 can be aquired.By means of X ray structure analyser and TEM,the exper imental results prove that the sulfonitriding layers consist mainly of FeS,Fe 3O 4 and Fe 2N phases,and the penetration depth of sulphur can't exceed 50μm.The sulfonitriding layer possesses good wear and thermal fatigue resistance.
