Abstract
The present invention relates generally to an oxidation and corrosion resistant coating composition produced by a vapor phase co-deposition of transition metals on metallic components. In particular, this coating includes aluminum and silicon and the coated substrate may comprise precious metal, nickel, cobalt or MCrALY. Such coatings are particularly useful in protecting nickel and cobalt and iron-based superalloys from heat corrosion and oxidation attack, especially during high temperature operation, e.g., gas turbine and jet engine hot zones.
