METHOD FOR REPAIRING TITANIUM ALLOY COMPONENTS

摘要

A method for repairing a titanium alloy surface of a turbine component (150) includes the step of cold gas-dynamic spraying (204) a powder material comprising at least one titanium alloy directly on the titanium alloy surface. The method may further include the steps of hot isostatic pressing (208) the cold gas­dynamic sprayed turbine component (150), and performing a separate heat treating step (210) after the hot isostatic pressing. Thus, the cold gas-dynamic spray process and post-spray processing can be employed to effectively repair degraded areas on compressor turbine components.
