ABSTRACT:
A combustion turbine component (10) includes a combustion turbine component substrate (16) and an alloy coating (14) on the combustion turbine component substrate. The alloy coating (14) includes nickel (Ni), chromium (Cr), aluminum (Al), and yttrium (Y). Furthermore, the alloy coating includes at least one of titanium (Ti), tantalum (Ta), tungsten (W), and rhenium (Re). The alloy coating also includes at least one rare earth element, and an oxide of at least one of the yttrium (Y) and the at least one rare earth element.
