| 金属基固体自润滑复合涂层具有强度高、耐高温、耐磨损以及易加工等特性，成为近来研究热点。首先综述了国内外金属基固体自润滑复合涂层的材料体系（即难熔金属基自润滑复合涂层、软金属基自润滑复合涂层、低温金属基自润滑复合涂层以及高温金属基自润滑复合涂层），随后分析了金属基固体自润滑复合涂层的润滑机理，指出润滑膜的低剪切特性是实现减磨润滑的关键。接着介绍了金属基固体自润滑复合涂层的制备技术，比较分析了烧结、电镀、化学镀、热喷涂、物理气相沉积（PVD）、化学气相沉积（CVD）、激光熔覆等技术，在制备金属基自润滑复合涂层方面的优点和不足。最后总结了目前在关于金属基固体自润滑复合涂层研究中存在的问题，进而探讨了相应的解决方案，提出应深入研究金属基体、固体润滑剂与环境三者之间的相互作用机理，并进一步指出研发新型固体润滑剂、改进现有制备技术、开发新工艺是未来重点发展的方向。 |
| 英文摘要: |
| 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 composite 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. |
