Notes:
The thrust surface of W615 engine is remanufactured by plasma transferred arc (PTA)powder surfacing technology. The Ni15 Nickle-based alloy powder is selected as deposited metal. Byoptimizing the welding procedure, the coating is free of crack and pore. The microstructurecharacteristics of deposition layer are investigated by metallographic microscope, and themicrohardness of the overlay is measured by vickers hardness tester. It is found that the heat affectedzone is narrow, the rate of dilution is low and the microhardness of deposition layer is about HV130which is close to that of base metal. Furthermore, the hardness of welding surface can meet the needsof the engine
