摘　　要：钛及钛合金在服役过程中会出现点蚀、应力腐蚀和电偶腐蚀等问题,因此对于钛及钛合金腐蚀行为的研究极为重要。综述了近年来钛及钛合金在海洋工程、航空工业、油气开采和化学工业中腐蚀行为的研究进展及存在问题,简要介绍了钛及钛合金表面处理技术取得的研究成果,最后对该领域发展趋势进行了展望:①在现有研究的基础上应更深入探究钛及钛合金在多影响因素耦合作用下的腐蚀失效行为及表面处理技术;②注重结合实验和数值模拟等手段从微观尺度探究钛及钛合金的腐蚀机理,加快建立钛及钛合金腐蚀性能等相关数据库;③进一步降低各种表面处理技术的成本,开发“复合防护”技术,深入探究能够提升钛及钛合金综合性能的新型表面处理技术。Titanium and its alloys may experience pitting corrosion,stress corrosion,and galvanic corrosion during service,making it extremely important to study the corrosion behavior of titanium and its alloys.This article reviews the research progress and existing problems of corrosion behavior of titanium and titanium alloys in marine engineering,aviation industry,oil and gas extraction,and chemical industry in recent years,and briefly introduces the research results of surface treatment technology for titanium and titanium alloys.Finally,the development trend of this field is prospected:①based on existing research,more in-depth exploration should be conducted on the corrosion failure behavior and surface treatment technology of titanium and titanium alloys under the coupling effect of multiple influencing factors;②pay attention to exploring the corrosion mechanism of titanium alloys at the micro scale through combining experimental and numerical simulation methods,and gradually establish databases related to the corrosion performance of titanium alloys;③further reduce the cost of surface treatment technologies for titanium alloys,develop“composite protection”technologies,deeply explore new surface treatment technologies that can improve the comprehensive performance of titanium and its alloys.
