<P>PROBLEM TO BE SOLVED: To provide a metallic honeycomb structure having good oxidation resistance even in extremely thin foil state. <P>SOLUTION: In a production method for the metallic honeycomb structure excellent in the oxidation resistance which forms the honeycomb structure by laminating or winding up a heat-resistant alloy-made flat foil and wavy foil or both wavy foils, after sticking metallic Al powder on the surface of this honeycomb structural body, the heating treatment is performed at a temperature not lower than the temperature at which Al is diffused into the heat resistant alloy foil. The Al powder is used in a flake form having ≥10 ratio of grain diameter/thickness. <P>COPYRIGHT: (C)2004,JPO |
