In-situ diffusion alloying and pre-oxidation annealing in air of FeCrAI alloy catalytic converter material |
摘要 |
A manufacturing method of metal substrate catalytic converter and the resulting product. In this method, a multiple layer aluminum and ferritic stainless steel composite material is first made by roll-bonding and then further processed to a final foil thickness. The composite foils are then fabricated to a honeycomb-like converter with air flow channels. The converter is then thermally treated at a high temperature during a necessary converter fabrication process. The monolithic FeCrAl alloy is then obtained in the converter by in-situ diffusion alloying with pre-oxide film on the surfaces. The resulted material has improved oxidation resistance and thermal dimension stability at a high temperature.
