Description of the Related Art A metal carrier is formed by stacking a flat plate made of a heat-resistant metal having a thickness of about 50 μm and a corrugated plate obtained by processing the flat plate in a spiral shape or alternately by superposing them to form a honeycomb body. It is configured to be stored and fixed in an outer cylinder made of corrosion-resistant and heat-resistant metal such as stainless steel.

合も十分に強固でなければならない。This metal carrier carries a catalyst for purifying exhaust gas such as platinum, palladium, rhodium and the like, and is mounted and fixed, for example, on an exhaust gas system of an automobile engine. The honeycomb body itself is of course subjected to a severe heat cycle such as a rapid temperature increase or decrease or rapid cooling when the vehicle is stopped, and is exposed to a high temperature gas flow rate of several tens of m / sec, or violently vibrates during traveling. That is, the bonding between the honeycomb body and the outer cylinder must be sufficiently strong.

ルあるいは排ガス浄化機能が低下する問題がある。Therefore, if the honeycomb body or between the honeycomb body and the outer cylinder is entirely rigidly bonded, a large stress is generated in the vicinity of the bonded portion due to the heat cycle thereof, and thermal fatigue causes the outer cylinder and the honeycomb body. There is a problem that the joint part of the honeycomb body is broken, or the honeycomb body is broken and the honeycomb body is displaced, or the inside of the honeycomb body is broken to form a gap, which causes engine trouble or deteriorates the exhaust gas purification function.

る。In order to prevent this, the entire contact portion between the flat plate and the corrugated plate of the honeycomb body is not joined, and, for example, Japanese Patent Publication No. 63-4.
As disclosed in Japanese Patent No. 4466, a method of brazing only at least one end face side of the honeycomb body or West German Patent Publication No. 3,
No. 312,944, a corrugated plate and a part of a flat plate are joined together to form a flexible joint structure, or as disclosed in Japanese Utility Model Laid-Open No. 62-194436. The structure which joins a cylinder locally is proposed.

公報では拡散接合することが記述されている。However, in each of these examples, the specific contact portion between the flat plate and the corrugated plate is joined by brazing. However, in order to braze, in addition to the technical and cost problems that the brazing material must be accurately supplied to the joint,
There is a problem that the brazing material component diffuses into the flat plate or corrugated plate and deteriorates its properties such as high temperature strength and oxidation resistance, or if too much brazing material is supplied, the flat plate or corrugated plate is corroded. Therefore, without using the brazing material,
Those which are joined by high-density energy such as an electron beam or a laser as disclosed in JP-A-4-13462 and JP-A-63-36843, and a flat plate and a wave by resistance welding as in JP-A-54-13462. Although joining of plates has been proposed, all of these have a limitation in the joining speed, and there is a limit to increase productivity and reduce cost. Further, Japanese Unexamined Patent Publication No. Sho 56-85514 describes sintering of the contact portion, and Japanese Unexamined Patent Publication No. 1-218636 describes diffusion bonding.

接合することを提案している。Although it is possible to solve the above-mentioned problems in characteristics or work by such sintering and diffusion bonding, it is necessary to obtain sufficient strength of the bonded portion by these treatments. It is necessary to apply a considerably large surface pressure to the contact surface between the flat plate and the corrugated plate. To meet this requirement, Japanese Patent Laid-Open No. 14747/1990 discloses that the outer cylinder containing the honeycomb body is squeezed so that the contact between the flat plate and the corrugated plate and the contact between the honeycomb body and the outer cylinder (contact pressure). It is proposed that the diffusion bonding be performed after the improvement.

加えることなく、単に面圧のみで拡散接合する従来の方
法は不完全であることが判明した。As described above, many proposals have been made for diffusion bonding. However, not only the honeycomb body manufactured by a usual method but also the outer tube can be squeezed to have a narrowing effect. It is effective only in the vicinity of the outer periphery of the honeycomb body and tends to be insufficient in other places. Therefore, when the same carrier is mounted on an engine and subjected to a durability test, a flat plate or a corrugated foil may be partially broken and may fail. By squeezing the outer cylinder, by pressing the flat plate and the corrugated plate to increase the force,
The purpose is to raise the contact surface pressure to perform good diffusion bonding, but the foil thickness is extremely thin at 50 μm, and since it is easily deformed, the contact surface pressure does not substantially increase and microscopic contact is achieved. This is because the point-to-point contact results in discontinuous point-like diffusion bonding instead of continuous line-like diffusion bonding along the contact line between the flat plate and the corrugated plate. As a result, it was found that the conventional method of simply performing diffusion bonding only by the surface pressure at the contact portion between the flat plate and the corrugated plate without any treatment for bonding was incomplete.

Is a heat treatment in a non-oxidizing atmosphere to perform diffusion bonding of a honeycomb body, and (2) a liquid coating agent containing ultrafine powder that promotes diffusion bonding is used as a metal. It is applied to a predetermined area on the outer surface of the corrugated plate, laminated or wound with a metal flat plate, heat-treated in a non-oxidizing atmosphere to diffuse-bond the honeycomb body, and then inserted into the outer cylinder and mechanically or brazed.

The above method for producing a metal carrier is characterized in that a honeycomb body laminated or wound with a metal flat plate is incorporated into an outer cylinder, the outer peripheral surface of the honeycomb body is compressed, and then heat treatment is performed in a non-oxidizing atmosphere.

In order to obtain the part, we replenish the microscopic point contact part with ultrafine powder,
The ultrafine powder is melted by heat treatment in a non-oxidizing atmosphere,
First, the contact is made continuous, and then this is diffused into a flat plate and a corrugated plate, so that the contact portion is also diffusion-bonded. The ultrafine powder is used because the bonding promoter is applied to the corrugated sheet before being wound or laminated, and when this is combined with a flat plate, the bonding promoter gets caught between the corrugated plate and the flat plate. This is because if the value is large, a space is not filled and a gap is formed when the diffusion heat treatment is performed.

A honeycomb body 10 having a thickness of 0 mm is formed, and the liquid coating agent 2 is applied to the outer surface of the outer cylinder 1 having a diameter D 4 = 85 mm and a height B 1 = 100 mm by coating the lower half 50 mm of the honeycomb body 10 (c1).
2 (c2), reduce the outer diameter to 84 mm, and then use a vacuum furnace to 1
The carrier A was manufactured by performing heat treatment at 200 ° C. for 30 minutes. On the other hand, a carrier B having the same size was manufactured by the same method except that the liquid coating agent 2 containing the ultrafine powder 1 was not applied to the corrugated plate 5.
