Title:
【発明の名称】排気ガス浄化用触媒を担持するための金属製担持母体の製造方法
Document Type and Number:
Japanese Patent JP2545564
Kind Code:
B2
Abstract:
A metal-made carrier body is fabricated for an exhaust gas cleaning catalyst. At least one sheet-like metal band and at least one corrugated metal band, each of said bands being made of a thin metal sheet, are superposed one over the other so as to establish contacts therebetween, thereby forming a multi-layered composite body defining a number of network-patterned gas flow passages along the central axis thereof. The composite body is dipped in an electroless plating bath capable of forming a brazing coating layer on the composite body so as to form a brazing coating layer at least in the vicinity of each contact except for the contact itself. The composite body is then subjected to a heat treatment so as to braze the contacts between the sheet-like metal band and corrugated metal band. Before dipping the composite body in the plating bath, it may optionally be enclosed in a cylindrical metal casing. The composite body and cylindrical metal casing are also brazed together at their mutual contacts.
