METHOD OF SOLDERING HEAT RESISTING ALLOY HAVING INSULATING OXIDE FILM ON ITS SURFACE, AND PREHEATED TYPE EXHAUST GAS CLEANING METAL SUPPORT AND METHOD OF MANUFACTURING THE SAME. |
摘要 |
This invention aims at manufacturing a metal support capable of activating a catalyst in a short period of time, and, especially, a method of combining an insulating film-carrying heat resisting alloy having an insulating film consisting mainly of alumina with a heat resisting alloy by arranging a forcibly reducing metal capable of thermodynamically reducing alumina and a solder-laminated bond so that the forcibly reducing metal is in contact with the insulating film-carrying heat resisting alloy, and soldering these metals to each other by heating the same in a non-oxidizing atmosphere. Consequently, only the portions that are to form conductive passages in a honeycomb structure can be combined, and heat resisting metals having insulating oxide films on the surfaces thereof firmly so that they have conductivity. A preheated type metal support capable of being heated at a limited surface layer portion on its exhaust gas inlet side and having excellent cleaning performance can be provided by using this soldering method. <IMAGE> |
