いた。As a method for joining ceramics and metal by brazing (hereinafter simply referred to as brazing), for example, Japanese Patent Application Laid-Open No. 59-21
After metallizing ceramics in advance by the method disclosed in Japanese Patent Publication No. 7884 and Japanese Patent Application Laid-Open No. 21888, and inserting a brazing material between the joint surface of the metallized ceramic and the metal, the ceramics are heated in a furnace. For ceramics without metallization, a brazing material containing an active metal such as TI is inserted between the ceramic and the metal and heated in a vacuum furnace. The method of attaching was commonly used.

る反りや曲がりを生じる問題も抱えていた。However, because the difference in expansion between ceramics and metals is extremely large, brazing as described above often causes ceramics to break. Furthermore, when a large number of ceramics are placed over the entire surface of a metal and brazed in a furnace, there is a problem in that the ceramics warp or bend due to the difference in expansion during the cooling process to room temperature.

に開示されている。In order to solve such problems, for example,
As disclosed in Japanese Patent No. 227782, an insert metal having a melting point lower than that of the ceramic and the metal is sandwiched between the ceramic and the metal as a thermal stress buffering material, and magnetism is applied from the front side of the ceramic piece and high-frequency induction heating is performed to absorb the heat. Techniques have also been provided to absorb differential expansion. Separately, during the brazing process between a metallized ceramic plate and a metal plate, that is, when the brazing material is in a molten state, a load is applied to the center part of the ceramic side, which has a small coefficient of thermal expansion, and the S-temperature decreases. JP-A-02-2413877 discloses a method of solidifying a brazing filler metal to obtain a bonded state between a ceramic plate and a metal plate free of internal stress.

ミックスが破壊していまう問題があった。(Problems to be Solved by the Invention) As mentioned above, when brazing a large number of ceramics 1 and a bonding base material in a furnace, due to the difference in the amount of shrinkage between the ceramics and the bonding base material during the cooling process, A large restraining force acts on the ceramic bonding surface of the bonding base material, causing the bonded product to warp significantly with the ceramic bonding surface facing up. When a bonded product with such warpage is attached to a smooth equipment structure, the warp is corrected and the ceramic There was a problem that large stress was applied to the ceramics, causing them to break.

If the bonding base material is thick enough to restrict thermal expansion due to local heating, warping of the bonding base material will not occur.

法が提案されているが、接Ｑ４’Ｊ材が薄い場合の接合
母材の反り防止には抜本的な解決策は見当らない。However, in recent years, there has been a demand for ceramic-metal joints used for structural purposes to reduce weight by making the joining base material thinner. If brazed in this condition, the bonded base material will warp. On the other hand, in the method of applying a load to ceramics during brazing to prevent residual stress, it is necessary to give the ceramics a reverse warpage commensurate with the amount of warpage of the joining base material after brazing. Normally, ceramics will crack. As described above, various methods have been proposed in the conventional method, but no drastic solution has been found to prevent warping of the joining base material when the joining Q4'J material is thin.

。FIG. 1 shows the back side of the bonding base material 1, in which bolts 2 are installed. This joining base material 1 is a metal plate, and steel is usually used, but the material is not limited at all. The bolt 2 is attached to the joining base material 1 by a commonly used means such as welding (including spot welding) or screwing. A restraining plate 3 is fixed to the bonding base material 1 with bolts 2 and nuts 4, as shown in FIG. The restraining plate 3 is used to prevent the joining base material from warping during brazing by fastening the joining base material using the bolts 2 and nuts 4, and is made of a material that maintains rigidity at high temperatures, such as steel, stainless steel, or ultra-high temperature. An alloy or the like can be used, and the thickness is sufficient to prevent warping of the joining base material. In this example, a plate made of 5S41, which is inexpensive and easy to process, and has a thickness of 15 m was used. Note that the bolts 2 and nuts 4 were made of commonly used steel.

系等を用いることができる。In the figure, 5 is a ceramic piece, which is bonded to the surface of the bonding base material. The material of the ceramic piece 5 is not particularly limited, and alumina-based, silicon carbide-based, silicon nitride-based, etc. can be used.

。Note that ceramics must be metallized in advance, and various metallization methods can be used, but in this example, well-known copper metallization and active metal metallization were used.
本発明においては、前記した接合母材へのセラミックス
片の接合を高周波誘導加熱により行う。In the present invention, the ceramic piece is joined to the above-described joining base material by high frequency induction heating.
これは、炉中ろう付けでは接合母材と拘束板の全部が熱
膨張するため、拘束力が働かなくなり、接合母材の反り
防止はできないためである。すなわち、高周波誘導加熱
では、加熱コイル下のろう付けスポットのみが局所的に
かつ短時間加熱され、その他の部分はろう付け温度より
はるかに低い温度に維持される。This is because in furnace brazing, the joining base material and the restraining plate all thermally expand, so the restraining force no longer works, and it is not possible to prevent the joining base material from warping. That is, in high-frequency induction heating, only the brazing spot under the heating coil is heated locally and for a short time, and the other parts are kept at a temperature much lower than the brazing temperature.

例ではろう付けスポットの長さのほぼ３〜５倍程度とし
た。Moreover, since the bolts are arranged at specific intervals as shown in FIG. 1, the bonding base material is constrained by the constraint plate within this range. Therefore, the thermal expansion due to heating of the brazing spot of the joining base material is restricted by the restraining force of other parts of the joining base material that are not heated. As a result, bending and warping of the joining base material can be reliably prevented. The set interval of the bolts in the present invention varies depending on the thickness and material of the base material to be joined, but in this embodiment, it is approximately 3 to 5 times the length of the brazing spot.
第３図は接合母材１を拘束板３に点付溶接６で固定した
場合の例を示す。FIG. 3 shows an example in which the joining base material 1 is fixed to the restraining plate 3 by spot welding 6.

ことが好ましい。Spot welding 6 is performed at predetermined intervals on the outer periphery of the joint base material 1 and the restraining plate 3 in contact with each other. The spacing between spot welds can be approximately 3 to 5 times the length of the brazing spot, similar to the bolt installation spacing, and the number of spot welds can be reduced, especially at the four corners, since the others can be restrained in one place. , it is preferable to carry out spot welding at the four corners.

、曲げや反りの発生を防ぐことができる。The joining of the ceramic piece 5 to the surface of the joining base material 1 and the joining method thereof are performed in the same manner as in the case of bolt restraint (FIG. 2) described above. In other words, by high frequency induction heating,
When the ceramic piece 3 is brazed to the joining base material 1, since the joining base material is restrained by the restraining plate via the spot weld, bending and warping can be prevented from occurring.

ができる。In Fig. 4, bolts 2 are fixed to the central part of the joining base material 1, and after this joining base material 1 is fixed to the restraining plate using bolts and nuts, the outer peripheral part is fixed as shown in Fig. 3. Spot weld at specified intervals. In the example shown in FIG. 3, the bonding base material 1 and the restraining plate 3 are fixed only by spot welding on the outer periphery, but in this case, the restraining force at the center may be insufficient. Therefore, by adding the restraint by the bolt 2 in Fig. 4,
- The layer restraint area can be narrowed. Therefore, the position and number of bolts to be installed in this case can be appropriately selected based on the size, thickness, etc. of the joining base material. Note that the implanted bolts can be removed and used depending on the environment and location where the joined body is used.
