<p>Provided are: a heat-resistant alloy member which is capable of suppressing cracks or separation of a protective oxide coating film that is formed on a reservoir layer even when used in an environment where a heat cycle is applied thereto in a high temperature corrosive atmosphere, in said heat-resistant alloy member, the amount of expensive Pt added into the reservoir layer being significantly reduced or addition of Pt being not necessary; and a method for producing the heat-resistant alloy member. A heat-resistant alloy member is configured by sequentially laminating a diffusion barrier layer (40), a reservoir layer (20) and a stress relaxation layer (50) on the surface of a metal base (10). The diffusion barrier layer (40) is formed of an alloy that contains Re. The reservoir layer (20) is formed of an alloy that contains Al. The stress relaxation layer (50) is formed, for example, of an oxide ceramic that contains Zr, Y, O and at least one metal selected from the group consisting of Ni, Al, Cr, Ti, Hf, Ta, W, Re, Co and Mo. A protective oxide coating film is formed on the reservoir layer (20).</p> |
