摘　　要：渗硫层能有效降低零件的摩擦系数,提高零件的抗擦伤性能和耐磨性能,但是单纯的低温离子渗硫不能保证特定工况的生产要求,选用其它处理技术与低温离子渗硫相结合的复合处理方法可以制得表层软、亚表层硬的理想固体自润滑涂层。综述了离子多元复合渗法(S-N,S-C-N,S-O,S-Mo),两步法(喷丸和超音速纳米化处理与低温离子渗硫、预置薄膜涂层与低温离子渗硫、激光处理技术与低温离子渗硫),以及多种复合处理技术相结合法的特点和部分应用实例,着重介绍了每种复合处理技术的工艺。针对目前复合处理技术在固体自润滑薄膜制备中存在的问题,提出复合处理技术的发展方向。Sulfurizing layer can effectively decrease the coefficient of friction, improve the anti-scratch properties and wear re- sistance of the parts, but solely low-temperature ion sulpburization cannot guarantee to meet the production requirements of specific conditions, the composite processing method of other technologies and low-temperature ion sulfurization result in ideal solid self-lu- bricating coating with soft surface and hard subsurface, which meets the needs of the production environment. This paper reviewed the characteristics and part of the research instances for the ion multiple composite infiltration method （ S-N, S-C-N, S-O, S-Mo）, two-step method （shot peening processing, supersonic nanocrystallization processing and low temperature ion sulphurization; preset film coating and low temperature ion sulphurization; laser processing technology and low temperature ion sulphurization） , combined method involving a variety of composite processing technologies. Each process of composite processing technology was introduced in detail. The direction of development of composite processing technology was suggested based on the current problems of complexprocessing techniques in self-lubricating solid preparation.
