Plasma Transferred Arc Powder Surfacing Technology of Thrust Face

Abstract:

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. By optimizing the welding procedure, the coating is free of crack and pore. The microstructure characteristics of deposition layer are investigated by metallographic microscope, and the microhardness of the overlay is measured by vickers hardness tester. It is found that the heat affected zone is narrow, the rate of dilution is low and the microhardness of deposition layer is about HV130 which is close to that of base metal. Furthermore, the hardness of welding surface can meet the needs of the engine.
