Description of the Related Art A metal carrier for a catalyst device used in a conventional exhaust gas purifying apparatus has a brazing filler metal interposed between a thin metal flat plate and a corrugated plate, and the flat plate and the corrugated plate are superposed and rolled into a roll from the center. A honeycomb body is formed, a brazing material is melted using a high vacuum furnace, and joining is performed at a contact portion of the plate materials. A Ni-based brazing material was used as the brazing material, and a ferritic stainless steel material was used as the flat plate and the corrugated plate. A honeycomb carrier formed in such a manner and housed in a metal outer cylinder is known as a metal carrier for a catalyst device. (For example, JP-A-56-4373).

内でできるだけ薄くなっている。A catalyst supporting layer made of alumina or the like is formed on the surface of the honeycomb passages of the honeycomb body, and a noble metal catalyst is supported on the catalyst supporting layer and functions as an exhaust gas purifying catalyst. Then, it is arranged in the exhaust passage of the internal combustion engine to purify HC, CO, NO x, etc. in the exhaust gas. Since it is necessary to secure as large a honeycomb passage area as possible in a limited volume, the thickness of the flat plate and the corrugated plate is made as thin as possible within a range where strength can be maintained.

し易く機械的強度が低下するという欠点がある。In the above-mentioned conventional metal carrier for a catalytic device comprising a honeycomb body, since a brazing material is sandwiched between a flat plate and a corrugated plate, they are superposed and formed.
The molding process is complicated and difficult, the shape of the honeycomb body becomes inaccurate, and in order to avoid oxidation due to heating in the bonding process of the brazing material, bonding must be performed in a non-oxidizing atmosphere using a high vacuum furnace. There is an annoyance that it does not happen.
Further, in a honeycomb body in which a Ni-based brazing material is used as a brazing material and a ferrite-based material is used as a plate material in order to avoid the use of a high vacuum furnace, the brazing material and the plate material have different thermal expansion coefficients, and therefore are used in a high temperature environment. In this case, there is a drawback that thermal fatigue is likely to occur at the joint and mechanical strength is lowered.

It is an object of the present invention to provide a metal carrier for a catalyst device, which can be joined without using a high vacuum furnace, and which does not cause thermal fatigue at the joined portion, and therefore can prevent the plate material from breaking.

係数の差による影響は少なくなる。[Function] A honeycomb body is formed by applying a self-fluxing alloy layer in advance on at least one surface of a corrugated sheet material to be joined and a metal plate constituting the flat sheet material, and the honeycomb body is heated to a melting temperature of the self-fluxing alloy layer. The self-fluxing alloy layer is melted by heating until the two plate members are joined to each other at the contact portion to form a honeycomb body. Since no individual brazing material is sandwiched between the plate materials to be joined, it is possible to form a honeycomb body having an accurate shape. Since the joint surface is covered with the Ni-based self-fluxing alloy layer, it is not necessary to use a high vacuum furnace because oxidation of the plate materials can be avoided during the joint. In addition, since the self-fluxing alloy layer is formed by the ion plating method, the layer can be made thin, and therefore the joining layer formed at the joining portion after joining can also be made thin, so that the heat between the joining layer and the plate material can be reduced. The influence of the difference in expansion coefficient is reduced.
