摘　　要：轻金属材料(铝、镁、钛及其合金等)具有质轻、比强度高等优良性能,被广泛应用于航天航空、汽车电子、海洋工程等机械领域,但化学性质活泼易腐蚀、硬度低易磨损等性质限制了其使役寿命及使用范围。为提升轻质材料表层界面的耐腐蚀性能和摩擦学性能,微弧氧化作为有效的表面强化技术得到了广泛研究。对基于微弧氧化处理铝、镁、钛及其合金表面,并采用复合技术制备耐磨、减摩复合涂层的研究现状进行了一个系统的总结。将复合技术分为三类:第一类,前处理(机械预处理、预置膜层)+微弧氧化;第二类,微弧氧化直接复合技术(减摩复合、抗磨复合);第三类,微弧氧化+后处理(抛光、重熔、固体润滑涂层)。介绍了三类复合技术的制备工艺、注意事项,分析了其对运动摩擦副部件摩擦学性能的影响及优化方向。最后,指出了微弧氧化陶瓷膜层在摩擦学应用领域所面临的挑战,并从陶瓷膜层结构设计制备、增强韧性、降低对基体疲劳性能的影响和摩擦润滑机理等方面展望了其发展方向。Light metal materials(aluminum,magnesium,titanium and their alloys)are widely used in aerospace,automotive electronics,marine engineering and other mechanical fields due to their excellent properties such as light weight,high specific strength,etc.However,their service life and use range are limited because of lively chemical properties,easy corrosion,low hardness and easy wear.In order to improve the corrosion resistance and tribological properties of the surface interface of lightweight materials,micro-arc oxidation has been widely used as an effective surface strengthening technology.The research status of micro-arc oxidation treatment on the surface of aluminum,magnesium,titanium and their alloys,and the use of composite technology to prepare wear-resistant and anti-friction composite coatings were summarized systematically.The composite technology was divided into three categories:the first was pre-treatment(mechanical pretreatment,preset film layer)+micro-arc oxidation;the second was micro-arc oxidation direct composite technology(friction reduction composite,anti-wear composite);and the third was micro-arc oxidation+post-treatment(polishing,remelting,solid lubricating surface coating).The preparation technology and precautions of three kinds of composite technologies were introduced.The influence on tribological performance of moving friction pair parts and its optimization direction were analyzed.Finally,the challenges of micro-arc oxidation ceramic coatings in the field of tribology were pointed out,and its development direction was prospected from the aspects of ceramic film structure design and preparation,strengthening of toughness,reduction of impact on the fatigue performance of the substrate,and friction lubrication mechanism.
