Abstract

See full text

A method and resulting gas turbine engine component (40) having a protective layer of metallic glass (14) deposited over a superalloy substrate (12). A further layer of ceramic insulating material (42) may be deposited over the metallic glass. The metallic glass functions as a bond coat to provide thermal insulation and mechanical compliance. The metallic glass may be deposited onto the substrate by a flux mediated laser deposition process wherein powdered alloy material (18) is melted together with powdered flux material (20). The flux material can facilitate the glass forming process by adding to the solidification confusion effect and/or by providing an active cooling effect.
