PURPOSE: To manufacture the Zr alloy member excellent in wear resistance and erosion resistance by forming the structure at least of a surface layer part in a Zr alloy member from the one of which ZrC is dispersed into a matrix.

CONSTITUTION: Zr or Zr alloy is mixed with carbon and/or metallic carbide or furthermore with hard grains, which is melted to disperse ZrC or hard grains except ZrC as well into a matrix. Or, the surface of a Zr or Zr alloy member is clad by welding with a cladding material of carbon and/or metallic carbide or furthermore contg. hard grains to form the structure of the surface layer part in the member from the one of which ZrC or furthermore hard grains except ZrC are dispersed into the matrix. Moreover, as the metallic carbide, Cr3C2, W2C, VC, Mo2C or the like are used, and as the hard grains, Al2O3, Cr2O3, ZrO2 or the like having about ≤150μ grain size are used. In this way, the Zr alloy member useful as the structural material for various chemical plants, nuclear power plants, etc., can be obtd.
