Optimized coating procedure for the protection of TiAl intermetallic alloy against high temperature oxidation

The interest for TiAl intermetallic alloys is growing in the last years because of their excellent ratio between mechanical properties and density. However, the application is restricted at temperatures up to 873–973 K by the resistance to oxidation. For this reason it is of great importance to study protective coatings able to raise its temperature of performance above 1073 K.
