Plasma electrolytic oxidation of Titanium Aluminides

IOP Conference Series: Materials Science and Engineering, 2016
Due to their outstanding specific mechanical and high-temperature properties, titanium aluminides exhibit a high potential for lightweight components exposed to high temperatures. However, their application is limited through their low wear resistance and the increasing high-temperature oxidation starting from about 750 °C.
