METHOD FOR PRODUCING A METALLIC SUBSTRATE USED FOR AUTOMOBILE EXHAUST GAS PURIFYING DEVICE |
摘要 |
A method for producing a metallic substrate used for an automobile exhaust gas purifying device, which comprises the steps of: preparing a heat-resisting steel member having a length and capable of containing therein other members; densely filling the heat-resisting steel member with easy-soluble material members and with stainless steel members for separating the easy-soluble material members from each other, to form a filled body; hot-working the filled body to reduce the cross sectional area thereof for achieving a metallic bond between the stainless steel members; cutting the filled body to a predetermined length; and removing the easy-soluble material from the filled body by a chemical and/or an electrochemical treatment for boring throughholes to expose catalyst carrier-destined surfaces of the stainless steel. |
