摘　　要：钢铁材料由于其优异的力学性能广泛应用于各个领域,然而钢铁的腐蚀失效一直是人们困扰的问题。有机涂层因其优异的结合力、简单的制备工艺和出色的长期防腐性能常用于钢铁表面的腐蚀防护。有机涂层中材料种类、填料取向、改性方法等对涂层腐蚀性能和摩擦性能都有一定的影响。综述了近年来钢铁表面有机涂层耐蚀与摩擦性能的研究进展。首先从物理阻隔、牺牲阳极的阴极保护、自修复技术和超疏水技术4种提高有机涂层耐蚀性的方法入手,阐述了各种方法的基本原理,探讨了4种方法所制备的用于钢铁表面防护的有机涂层的防腐性能,并对目前各种方法所制备的有机涂层存在的问题以及改善措施进行了分析。接着主要从掺杂填料的角度,探究了不同填料对钢铁表面有机涂层摩擦性能的影响,提出了润滑相/增强相协同作用、软硬协同作用和自润滑微胶囊3种提高有机涂层摩擦性能的策略。最后总结了目前钢铁表面有机涂层面临的一些挑战,并对钢铁表面有机涂层的发展方向进行了展望。Steel is widely applied in various fields due to its outstanding mechanical properties.However,the corrosion of steel has been a puzzling problem for a long time.Organic coatings are commonly used for protecting steel from corrosion effects due to their excellent adhesion,simple process of preparation,and superior long-term corrosion resistance.The types of materials,the orientation of fillers,and methods of modification in organic coatings have a certain impact on the corrosion and tribological performance of the coatings.The work aims to briefly introduce the research progress on anti-corrosion and tribological performance of organic coatings on steel in recent years.Firstly,four methods of improving the corrosion protection performance of organic coatings were introduced in sequence,including formation of physical barriers,cathodic protection at the expense of the anode,self-healing technology and superhydrophobic technology.The basic principles of each method were elaborated,and the corrosion protection performance of organic coatings on steel prepared by various methods was compared.Then,the problems of organic coatings prepared by the four methods were analyzed.The dispersion and orientation of two-dimensional materials in organic coatings greatly affected the barrier properties.How to achieve good compatibility and parallel distribution of two-dimensional materials in coatings was the key to improving the corrosion resistance of coatings.The method of cathodic protection at the expense of the anode required a large amount of sacrificial materials to form a stable conductive network,which could lead to an increase in the porosity of coatings and a decrease in the adhesion between substrates and coatings.How to reduce the number of sacrificial materials added to coatings while ensuring the stability of electrical connections was a problem required to be considered in the current preparation of such coatings.The self-healing coatings should improve the mechanical properties on condition that the anti-corrosio
