ABSTRACT:
A powdered metal spray coating material comprises two or more of Ni, Cr and Co, and 0.1 to 1.0% by weight of Y based on the total weight of the spray coating material. If Co is present in this spray coating material, the content of Co is in a range of 20 to 40% by weight, and the balance is Ni and/or Cr. If Cr is present, the content of Cr is in a range of 15 to 30% by weight, and the balance is Ni and/or Co. Such powdered metal spray coating material is produced by melting and homogenizing starting metals in vacuum and forming them into a metal powder by a gas atomizer.
