AbstractPratt and Whitney Canada specializes on the design and manufacturing of aerospace gas turbine engines, which requires advanced technologies to extend components life to reduce maintenance cost. Laser cladding provides unique capabilities for repairing damaged components that currently are difficult or even impossible to be repaired using conventional methods. In this paper, laser cladding of IN-625 alloy was investigated. Testing results reveals that laser clad IN-625 on wrought IN-625 substrate demonstrates comparable or even substantially improved fatigue life as compared to the baseline IN-625 specimens at the room temperature as well as at elevated temperature. Laser clad IN-625 also shows slightly improved wear resistance. Therefore, laser cladding of IN-625 is very attractive for repairing various damaged wrought IN-625 components for aerospace gas turbine engines. A case study will also be presented on laser cladding of IN-625 to repair damaged fuel nozzles that currently can not be repaired using conventional method.
