Honeycomb body having a metallic foil with an oxide coat, foil having an oxide coat and method for producing an oxide coat on a metallic foil |
摘要 |
A honeycomb body, in particular a catalyst carrier body, includes metallic foil of high-temperature corrosion-resistant steel with connecting points and an oxide layer with a thickness of 60 to 80 or 70 to 75 nm on each surface. The foil is composed of steel with chromium and aluminum components, particularly 1 to 5% aluminum. The oxide layer is substantially aluminum oxide orγ-aluminum oxide with a uniform thickness having a tolerance of less than 10% or less than 5% on all surfaces. The oxide layer may be on a rolled foil having a mean surface roughness of greater than 0.3 or 0.5μm or approximately 0.6μm in rolling direction and/or transversely thereto. The honeycomb body is durable under high loads and has defined connecting points. A foil having an oxide coat and a method for producing an oxide coat on a metallic foil are also provided. |
