PURPOSE: To produce a heat resistant member having a heat resistant coating layer formed via a binding layer to the surface of a metal as a base material.
CONSTITUTION: This member is a heat resistant member which has a layer 3, formed via a binding layer 2 on the surface of a metallic base material 1 and composed essentially of partially stabilized zirconium oxide, and a layer 4 composed essentially of aluminum oxide and formed on the surface of the layer composed essentially of partially stabilized zirconium oxide. By this method, this member has a heat resistant coating layer excellent in steam corrosion resistance and high temp. erosion resistance as well as in thermal insulation effect even under high temp. conditions and also a remarkable effect of having superior durability at high temp. can be provided.
