High temperature oxidation behavior and research status of modifications on improving high temperature oxidation resistance of titanium alloys and titanium aluminides: A review

Titanium alloys and titanium aluminides are widely utilized for structural applications in aerospace, automotive, military, sport equipment and chemical engineering due to their high specific strength, excellent corrosion resistance and stable moderate temperature properties. However, poor high temperature oxidation resistance limits their more extensive practical applications. In this paper, oxidation thermodynamics and kinetics of titanium alloys and titanium aluminides at high temperature are analyzed. Recent research progresses of modification including whole alloying modification and surface modification on improving high temperature oxidation resistance of titanium alloys and titanium aluminides are reviewed. The development trend of modification on high temperature oxidation resistance of titanium alloys and titanium aluminides in the future is forecasted. (C) 2016 Published by Elsevier B.V.
