2Cr13 martensitic stainless steel blades for nuclear power plant steam turbines are prone to water erosion during service and thin the tip of the blade. In this paper

the repair process of laser cladding Stellite 6 alloy powder was studied

and repair scheme design

process implementation and technical evaluation of the blade material were completed. The appearance size inspection

metallographic examination

ray inspection and hardness test results show that the laser cladding layer has uniform microstructure and no defects such as cracks

inclusions and non-fusion. The process of laser cladding Stellite 6 powder is very feasible. The microstructure of the cladding layer shows that the alloy grows in a dendritic shape perpendicular to the bonding surface of the cladding layer and the substrate

and the thickness of the cladding layer is up to 2 mm. The process is feasible for the repair of 2Cr13 blade of nuclear power plant steam turbine.
