Abstract
PURPOSE:To prevent the surface of a base from oxidizing or peeling off by providing a high specific surface area Al2O3 layer on a conjugate oxide layer of, Y, Ca or the like and Zr formed on a metal plate constituted of ferite group stainless steel, and carrying a catalyst on these layers. CONSTITUTION:One kind of more selected out of Y, Ca, Mg and Sc, and Zr are applied on a base constituted of at least 30wt.% or less Cr and 20wt.% or less Al and balanced Fe by means of impregnation, melt coating and so on. Then, said base is heat treated, and a high specific surface area Al2O3 layer is adhered to a conjugate oxide surface after forming a ZrO2 conjugate oxide film is formed on the surface of the base, and the high specific surface area Al2O3 is formed on the inner section and the surface of the composite oxide layer. Further, a metallic carrier catalyst for purifying exhaust gas is manufactured by carrying a catalyst on the conjugate oxide layer and the high specific surface area Al2O2 layer.
