Abstract
Disclosed is a process for coating a component of a TiAl alloy in order to improve the high-temperature resistance of the component. The process comprises depositing a Pt- and Cr-free protective layer alloy comprising Ti, Al, Nb, Mo and B and optionally one or more of W, Si, C, Zr, Y, Hf, Er and Gd on the component by physical vapor deposition at a temperature of less than or equal to 600° C. The protective layer alloy has a higher Al content than the TiAl alloy of the component. A coated component made by this process is also disclosed.
