Field of the Invention The present invention relates to a bonded body of ceramics and metal, and more particularly to a bonded body which can be advantageously applied as a wear-resistant member of a boiler, a paper machine or the like, or an insulating member of a battery.

接合体において、機械的接合法を適用したものは接合体
の形状や大きさに制約が多いこと、接合体の使用条件が
比較的狭いことなどの問題があり、その応用分野はごく
限られた一部の製品のみである。Among the bonded bodies of ceramics and metals, those to which the mechanical bonding method is applied have many restrictions on the shape and size of the bonded body, and the usage conditions of the bonded body are relatively narrow. However, its application field is limited to some products.
【０００４】一方、物理化学的方法によるセラミックス
と金属の接合体はこのような制約は比較的少ないが、高
温処理を伴うためセラミックスと金属との熱膨張率の差
に起因する熱応力により接合強度が低下したり、材質の
組合せによっては接合体が実現できない場合がある。On the other hand, the ceramic-metal bonded body by the physicochemical method has relatively few such restrictions, but since it involves high-temperature treatment, the bonding strength is caused by the thermal stress caused by the difference in the coefficient of thermal expansion between the ceramic and the metal. May decrease, or a bonded body may not be realized depending on the combination of materials.
【０００５】ろう付法の場合は、低融点のろう材を用い
て、このような問題を回避することが可能であるが、処
理温度が低くて接合強度が不十分な場合が多い。In the case of the brazing method, it is possible to avoid such a problem by using a brazing material having a low melting point, but in many cases the treatment temperature is low and the bonding strength is insufficient.
【０００６】本発明は上記技術水準に鑑み、接合強度が

接合体を提供しようとするものである。In view of the above-mentioned state of the art, the present invention is to provide a bonded body of ceramics and metal which has a high bonding strength and a wide range of material combinations.

接合強度が増すからである。[Function] A metal spray coating or a composite spray coating of metal and ceramics disposed between the ceramic and the brazing filler metal,
The joint strength between the thermal spray coating and the ceramic is relatively high, and the joint strength is further increased by the temperature during brazing. This is because, in the thermal spray coating, the molten particles collide with and adhere to the ceramic surface at a high speed, so that the micro distance between the two approaches and the bonding strength increases.

できる。On the other hand, the thermal spray coating and the brazing filler metal, and the brazing filler metal and the metal, are metallic, and their bonding strength is high.
If necessary, the thermal spray coating may be a composite coating of metal and ceramics to control the coefficient of thermal expansion thereof, reduce the generation of thermal stress during brazing, and improve the joint strength.

Make it of high quality.
