摘　　要：通过大塑性变形技术,可以细化晶粒,获得超细晶钛及其合金,明显提高其强度,但也会影响其耐腐蚀性能。综述了超细晶钛及其合金腐蚀行为的研究现状,讨论了晶粒尺寸、织构、位错密度、氧化膜厚度结构、组织均匀程度、晶界特征分布等因素对超细晶纯钛耐蚀性的影响。其中,最主要的影响因素是晶粒尺寸和织构。但是超细晶钛及其合金的耐蚀性受到多种因素的共同影响,各影响因素之间存在竞争关系。此外,基于当前的耐蚀化进展,对其未来的研究方向进行了展望。Ultrafine-grained(UFG)titanium and its alloys can be prepared by grain refining through severe plastic deformation(SPD)technology.For titanium alloys,the strength can be improved by SPD.However,the corrosion behavior may also be changed.The current research progress of the corrosion resistance of UFG titanium alloys is reviewed in this study.The effects of grain size,texture,dislocation density,oxide film thickness and structure,microstructure uniformity,and grain boundary on the corrosion resistance of UFG pure titanium are discussed.The grain size and texture are the most important factors that affect the corrosion behavior.However,the corrosion resistance of UFG titanium and its alloys is affected by many factors,and there is a competitive relationship between them.Furthermore,the future anticorrosive research direction is prospected based on the current research progress.
