Abstract This paper presents an overview of the corrosion behavior of titanium (Ti) alloys in both acidic and saline solutions. The solutions covered in this review are essentially the typical electrolytes encountered by Ti alloys when applied under service conditions. Although Ti alloys are generally known to be corrosion resistant, this review identifies strong reducing acids and fluoride-containing solutions as electrolytes that corrode Ti and its alloys. The pathways that the knowledge of the corrosion behavior of Ti alloys have followed from the 1950s to date are captured in this review. Based on this, the different factors influencing the corrosion behavior of Ti alloys are highlighted and the different research concepts for improving the corrosion resistance of Ti alloys in both solutions are discussed. The limitations of these research concepts are mentioned and the directions for future research are proposed.

钛合金在酸性和盐水介质中的腐蚀行为：合金设计、钝化完整性和电解质改性的作用

摘要 本文概述了钛 (Ti) 合金在酸性和盐水溶液中的腐蚀行为。本综述中涵盖的解决方案基本上是钛合金在使用条件下应用时遇到的典型电解质。尽管通常已知 Ti 合金具有耐腐蚀性，但本综述将强还原酸和含氟化物溶液确定为腐蚀 Ti 及其合金的电解质。本综述涵盖了从 1950 年代至今，关于钛合金腐蚀行为的知识所遵循的途径。在此基础上，突出了影响钛合金腐蚀行为的不同因素，并讨论了在两种解决方案中提高钛合金耐腐蚀性能的不同研究理念。
