METHOD OF REPAIRING NICKEL-BASED ALLOY ARTICLE |
| 摘要 |
<P>PROBLEM TO BE SOLVED: To provide a method for repairing a nickel-based alloy article giving a repaired portion having a fine crystal grain microstructure. <P>SOLUTION: A method for repairing nickel based alloy articles such as gas turbine rotors (12) generally includes removing a damaged portion (28) of the articles and laser cladding a high temperature nickel based alloy powder thereto to form a solid layer (30). The process can be repeated until a desired thickness is obtained. Optionally, a peening process subsequent to laser cladding can be implemented to introduce compressive stress to the solid layer (30) formed by laser cladding. <P>COPYRIGHT: (C)2009,JPO&INPIT |
