摘　　要：马氏体不锈钢表面沉积类金刚石(Diamond-like Carbon, DLC)薄膜提高了材料的耐磨性和耐腐蚀性。但由于马氏体基体与DLC涂层热膨胀系数和弹性模量不匹配以及界面原子的亲和性能差等因素,使得DLC涂层与马氏体基体间界面结合强度不够,存在涂层厚度有限等问题,从而限制了DLC涂层的进一步使用。针对以上不足,综述了国内外学者为提高马氏体不锈钢表面沉积DLC涂层的膜基结合力、耐蚀性所采取的有效措施和结果,主要包括基体表面氮化处理、优化工艺参数、设计一层和多层过渡层结构来缓和DLC涂层与马氏体基体结合力和耐蚀性的问题。最后,展望了马氏体不锈钢表面制备DLC防护涂层的发展趋势。The deposition of diamond-like carbon(DLC) coating on the surface of martensitic stainless steel improves the wear properties and corrosion properties of the material. However, as the thermal expansion coefficients and elastic moduli of the martensitic stainless steel and the DLC coating are not matched and the affinity of the interface atoms is poor, the bonding force between the DLC coating and the martensitic stainless steel is insufficient and the thickness of the coating is limited. As a result, the application of the coating is also limited. In view of the above deficiencies, the effective measures and achievements made by domestic and foreign scholars to improve the adhesion and corrosion resistance of DLC coating deposited on the surface of martensitic stainless steel were summarized. The measures mainly included nitriding treatment of the surface of martensitic stainless steel, optimizing process parameters, and designing one-layer and multi-layer transition layer structures to alleviate the problems of corrosion resistance and bonding force between DLC coating and martensitic stainless steel. Finally, the development trend of preparation of DLC protective coating on martensitic stainless steel surface was prospected.
