Sulfurizing layer can effectively decrease the coefficient of friction, improve the anti-scratch properties and wear resistance of the parts, but solely low-temperature ion sulphurization 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-lubricating 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 complex processing techniques in self-lubricating solid preparation.
