초록

A wide gap braze repair, particularly for a gas turbine engine vane or a component in the hot section of the engine. The repair is characterized by a braze filled void in a damaged area of the component, a laser shock peened surface over the repaired area of the braze filled void, and a region of deep compressive residual stresses imparted by laser shock peening (LSP) extending from the laser shock peened surface into the repair.

대표
청구항

A gas turbine engine component comprising: a metallic body including an exterior surface with a repaired area over a filled void in said body, said void filled with a metallic repair material extending up to said exterior surface, a laser shock peened surface on said exterior surface, and a region having deep compressive residual stresses imparted by laser shock peening extending into said filled void from said laser shock peened surface.
