Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1 . A cladding alloy powder comprising: 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. 2 . A method for producing an engine valve, comprising: melting the cladding alloy powder recited in claim 1 ; and cladding a valve face portion of an engine valve adapted to contact a valve seat with the melted cladding alloy powder. 3 . The method for producing an engine valve according to claim 2 , wherein the engine valve is adapted to be used for an engine in which an alcohol fuel, Liquefied Petroleum Gas or Compressed Natural Gas is used as a fuel.
