Titanium alloys are used in the manufacture of gas turbine aircraft engine compressor section components, which in use are exposed to high temperatures and corrosive environments. The platinum aluminide coatings described here have been developed to protect titanium alloys from oxidation and alpha case formation and can thus significantly improve the life of the alloys. The coatings showed a very low weight gain and alpha case formation did not occur during the entire period of exposure. The superior performance of the coating is due to the formation of a protective, adherent and continuous alumina scale on its surface. The results clearly suggest that this platinum aluminide coating is a prospective coating material to protect the titanium alloy components both from oxidation and alpha case formation.
