测定钛合金在氢氟酸、硝酸、柠檬酸水溶液中的阳极极化曲线,研究其组成相的电化学行为。证实电化学行为的差异是各相化学成分和点阵类型不同所致。在活化区内以α相和α′相的腐蚀为主;而在过钝化区以β相腐蚀为主。
The electrochemical behaviour, which is presented by means of ano-dic polarization curves, of the component phases in Ti and Ti alloys in aqueous so-lutions of fluorhydric acid, chlorhydric acid and amber acid has been investigated.The results indicate that the electrochemical behaviour of the alloy depends uponits composition and the lattice type. The corrosion of α and α' phase in active re-gion and that of β phase in passive region are the dominant corrosion behaviour.
