Method of repairing directionally solidified and single crystal alloy parts |
摘要 |
A new method is provided for repairing cracks in the outer surfaces of structural parts being a superalloy article having a directionally oriented microstructure, such as a blading member. The article may have internal passageways communicating through the end of the article. The method coats and seals cracked outer-surface areas of directionally solidified and single crystal structures by coating the defective area using a High Velocity Oxy-Fuel process (herein also referred to as HVOF), followed by hot isostatic pressing the part.
