摘　　要：钛合金具有优异的综合性能,在航空航天,汽车、医疗等领域被广泛应用。但其耐磨性较差,耐蚀性不能满足某些特殊环境的需求。利用微弧氧化(Micro-arc Oxidation,MAO)技术可在钛合金表面制备复合陶瓷涂层,以提高其上述性能。本文综述了电解液类型对钛合金MAO涂层耐蚀性影响的研究进展。Titanium alloy has excellent comprehensive properties and is widely used in aerospace,automotive,medical and other fields.But its wear resistance is poor,corrosion resistance can not meet the needs of some special environments.Micro-arc Oxidation(MAO)technology can be used to prepare a composite ceramic coating on the titanium alloy surface to improve its performance.In this paper,the research status of the influence of electrolyte type on the corrosion resistance of titanium alloy MAO coating is reviewed.
