Title:
METAL CARRIER FOR EXHAUST FAS PURIFICATION WITH EXCELLENT THERMAL FATIGUE RESISTANCE AND VIBRATION RESISTANCE AND PRODUCTION THEREOF
Document Type and Number:
Japanese Patent JP2709789
Kind Code:
B2
Abstract:
PURPOSE: To obtain a metal carrier with a structure with excellent durability which is not broken even in the case where a severe heat cycle of heating and cooling and an intense mechanical vibration are applied.
CONSTITUTION: In the metal carrier for purification of exhaust gas produced by bonding a metal honeycomb core body 6 formed by winding up a flat sheet 2 and a corrugated sheet 1 and a metal outer cylinder surrounding the outer periphery of the metal honeycomb core body 6, the bonding part or the flat sheet 2 with the corrugated sheet 1 and the bonding part of the outer periphery of the metal honeycomb body with the metal outer cylinder are constituted of a plurality of string-like or belt-like bonding belts. In addition, the thickness of a solder at the bonding part of the flat sheet 2 with the corrugated sheet 1 is at most 100μm and the positions of bonding parts on the surface and the rear face of the flat sheet 2 and the corrugated sheet 1 are different each other and the metal carrier for purification of exhaust gas exists through a non-bonding part with a length of at least 5% of the length of the honeycomb body 6 from the end face of the metal honeycomb core body on the exhaust gas introducing side and a method for preparation of the metal carrier for purification of exhaust gas is provided.
