Document Type and Number:
Japanese Patent JP4463359
Kind Code:
B2
Abstract:
A method for repairing the shroud surfaces of a gas turbine engine to provide corrosion and oxidation resistance of the shroud segments (10) while also restoring the dimensional integrity of the shroud segments (10) . The method entails removing the oxidation and corrosion products from the shroud segment (10) , removing preexisting coating materials, applying a material compatible with the shroud segment substrate material, machining the surface, applying a corrosion-resistant, oxidation-resistant and rub-compliant material to the shroud segment using a HVOF process, machining the shroud segment (10) to preselected dimensions and applying an aluminide coating for improved oxidation and corrosion resistance of the repaired surfaces.
