摘要： A honeycomb core for carrying a catalyst includes a flat metal foil and a corrugated metal foil, which are layered. The corrugated foil is configured by repeating a concavo-convex shaped part including a first top surface that is in contact with one of the flat foils, a second top surface that is in contact with another flat foil and is disposed at a position where the second top surface avoids the first top surface, and an inclined leg surface that has one end connected to the first top surface through a first bent part and another end connected to the second top surface through a second bent part, and extends in a direction inclined with respect to the first top surface and the second top surface, and has an offset part having different wave phases between front and rear in an axial direction of the honeycomb core.

摘要： A metal substrate for catalytic converter for purifying an exhaust gas includes a honeycomb core with metal flat foil and corrugated foil stacked in layers, and an oxide film having a thickness of 0.1 μm or more and 10 μm or less is formed in a predetermined range including an exposed end surface exposed toward the gas inlet side. The oxide film contains at least a first alumina including α-alumina and a Fe oxide. The α-alumina contains α-alumina with solid-solved Fe and α-alumina with no solid-solved Fe. In the oxide film, the content of the first alumina is 30% by mass or more and 99.5% by mass or less, the content of the Fe oxide is 0.5% by mass or more and 40% by mass or less, and the content of Fe is more than 7% by mass and 35% by mass or less.

摘要： A base for supporting a catalyst for exhaust gas purification, the base including a honeycomb structure obtained by superposing a metallic flat foil and a metallic wavy foil, characterized in that the wavy foil has offset portions where any adjoining two of the wave phases arranged in the axial direction of the honeycomb structure are offset from each other. The base is further characterized in that an oxide coating film has been formed in a given range of these offset portions which includes exposed edge surfaces that are exposed on the gas-inlet side, that the oxide coating film includes 30-99.9 mass % first alumina, with the remainder comprising at least one of second aluminas, Fe oxides, and Cr oxides, that the first alumina comprises α-alumina, that the second aluminas comprise one or more of γ-, θ-, χ-, δ-, η-, and κ-aluminas.
