摘要
There is provided by the present invention yttrium and yttrium-silicon bearing alloys which are chemically and mechanically compatible with advanced nickel-base superalloys and nickel-base eutectic superalloys and which posses excellent resistance to high temperature oxidation. The alloys of the invention are, therefore, particularly useful as a protective environmental coatings for the external surfaces of hot-stage aircraft gas turbine engine components, e.g., rotating blades and stationary vanes, made from such advanced superalloys.
