Evaluation of Oxidation of Ti-Al and Ti-Al-Cr Coatings Arc-ion Plated on Ti-60 High-temperature Titanium Alloy

Wei Yan

材料科学技术（英文）

High-temperature titanium alloy for aeroengine compressor applications suffers from high-temperature oxidation and environmental corrosion, which prohibits long-term service of this kind alloy at temperatures above 600°C. In an attempt to tackle this problem, Ti-48Al (at. pct) and Ti-48Al-12Cr (at. ...
