Abstract

PURPOSE:To improve the peeling resistance of the coating layer described in the title, by forming coating layer of ZrO2 type heat-resistant nonmetal on the prescribed surface of Ni base or Co base alloy with intervention of a Cr-enriched intermediate layer having a specific thermal expansion coefficient. CONSTITUTION:On the prescribed surface of a Ni base or Co base alloy previously blasted or degreased is formed a layer of high Cr alloy having thermal expansion coefficient of 1.12-1.4% at 0-1,000 deg.C by chemical gas-phase grow method, metallikon method, or vacuum evaporation method etc. After formation of the high Cr alloy layer, if necessary, the layer is heated to conduct dispersion between the layer and the base material alloy, thereby improving peeling resistance in thermal cycling. On the ground layer is formed by metallikon method a layer of ZrO2 type heat resistant metal, which is stabilized by the addn. of oxides such as Y2O3, Al2O3, MgO, or nitrides such as ZrN, HfN, TiN, CrN. The nonmetallic layer is excellent in peeling resistance and corrosion resistance because the layer has a thermal expansion coefficient nearly equal to that of the ground layer.
