Reparatur von Austrittskante und Plattform eines Turbinenbauteils durch Laserbeschichtung

摘要

A method of restoring a gas turbine engine component includes depositing a filler material (74) onto a sulphidation section (90) of an underside of a turbine engine platform (40b) and laser consolidating the filler material (74) to produce a restored surface on the underside. The sulphidation section (90) includes sulphidation pit portions (92) that are filled during the laser consolidating to produce the restored surface. An eroded trailing edge (38) of a turbine airfoil is laser cladded to produce a restored trailing edge thickness.
