为了提高钢铁材料的耐磨性一般多采用淬火、回火等硬化处理,但是,淬火时高温加热与随后的激冷可能引起变形,因此,处理后还得进行磨削。气体软渗氮,盐浴软渗氮,氨中渗氮,渗硫、硫氮共渗,蒸气处理、氧氮共渗等是在铁素体状态下进行的,这样,应力变形显著减少了,显著地改善材料的摩擦学特性。下面从摩擦学的角度来讨论这些工艺的特点。 In order to improve the wear resistance of steel materials generally use more hardening, tempering and other hardening treatment, however, quenching high temperature heating and subsequent cooling may cause deformation, therefore, have to be processed after grinding. Soft nitriding of gas, soft nitriding of salt bath, nitriding of ammonia, infiltration of sulfur, infiltration of sulfur, nitriding, steam treatment and oxynitriding are carried out under the condition of ferrite. In this way, the stress and deformation are remarkably reduced, Significantly improve the tribological properties of the material. The following tribology to discuss the characteristics of these processes.
