本文阐述了钛合金Ti-6Al-4V在三种不同环境中的腐蚀特性，模拟了不同温度下的化学、海洋和工业环境。结果表明，钛合金在低温和高温不同环境条件下均能形成保护性氧化膜。在不同环境和不同温度下评估的腐蚀速率相关。在不同环境中的点蚀研究表明，该合金是耐点蚀和缝隙腐蚀的海洋和化学环境中在两个温度下，但在工业环境中敏感。在不同温度和不同环境下观察到的腐蚀形态以及导致钛合金在各种环境条件下失效的降解机制相互关联。最后，根据不同技术获得的结果，推荐该合金用于制造各种环境条件下使用的组件。(C)2004年爱思唯尔公司All rights reserved.
The current paper explains the corrosion characteristics of titanium alloy Ti-6Al-4V in three different environments, which simulates chemical, marine and industrial environments at various temperatures. The results revealed that the titanium alloy could form a protective oxide scale under different environmental conditions studied at both low and higher temperatures. The corrosion rate evaluated in different environments and at different temperatures was correlated. The pitting corrosion studies in different environments revealed that the alloy is resistant to pitting and crevice corrosion in marine and chemical environments at both temperatures but susceptible in industrial environments. The corrosion morphologies observed at different temperatures and in various environments were correlated as well as the degradation mechanism that is leading the titanium alloy to fail under various environmental conditions. Finally, based on the results obtained with different techniques, the alloy was recommended to fabricate the components intended to use in a variety of environmental conditions.
