摘要:
Provided are a cladding alloy powder that can increase the wear resistance of a cladding alloy to be deposited and a counterpart member adapted to contact the cladding alloy, and a method for producing an engine valve using the cladding alloy powder. The cladding alloy powder includes 0.2 to 0.5 mass % C, 30 to 45 mass % Mo, 15 to 35 mass % Ni, 0.5 to 2.0 mass % Zr, and a balance including Co with unavoidable impurities. The method for producing an engine valve includes melting the cladding alloy powder, and cladding a valve face portion of an engine valve adapted to contact a valve seat with the melted cladding alloy powder.
