摘要：Metal-based solid self-lubrication composite coating has recently become a research focus due to its high strength, high temperature resistance, abrasion resistant and easy processing. Material systems of metal-based solid self-lubricating composite coatings were reviewed firstly (i.e., refractory metal-based solid self-lubricating composite coating, soft metal-based solid self-lubricating composite coating, low temperature metal-based solid self-lubricating composite coating, and high temperature metal-based solid self-lubricating composite coating). Lubrication mechanisms of metal-based solid self-lubrication composite coatings were then analyzed, it was indicated that low shear property was the key of antifriction and lubrication. Then preparation technologies of the coatings were introduced. Advantages and disadvantages of such technologies as sintering, electroplating, electroless plating, thermal spraying, physical vapor deposition (PVD), chemical vapor deposition and laser cladding were compared and analyzed. Finally, problems concerning study on metal-based solid self-lubrication com-posite coatings were summarized, corresponding solutions were discussed, and it was recommended to further study interaction mechanism among metallic substrate, solid lubricant and environment. It was pointed out that research and development of new solid lubricant, improving existing preparation technologies and developing new process were directions to be emphasized in the future.
