This relates to a solid phase joining method that provides strong joining without inserting a brazing material or intermediate layer.

欠点がある。Prior Art Conventional methods for joining metals or alloys with alumina include brazing, powder compression, hot pressing,
A hot isostatic pressing method (hereinafter referred to as HIP method) is known. In any of these cases, it is necessary to insert a brazing material or an intermediate layer at the bonding interface. The joined body joined by brazing filler metal is
When used at high temperatures, diffusion progresses and the bonding surfaces become heterogeneous, so there is a problem in that reliability is low when used at high temperatures. On the other hand, in the method of joining by inserting an intermediate layer such as hot press,
Since it involves a difficult process of controlling the composition, particle size, dispersibility, etc. of the intermediate layer, it has drawbacks such as high costs.

であつた。 In addition to the above method, there is also known a method of directly bonding metal or alloy and alumina by diffusion in a solid phase without inserting an intermediate layer. However, there are only a limited number of metals that can be bonded to alumina using this method, and only systems of Pt and alumina and Nb and alumina have been able to achieve a bond strength that is practical. In other words, it cannot be bonded with high strength to metals other than Pt and Nb, and its range of use has been extremely limited.

The purpose is to provide a method.

知見に基いて本発明を完成した。Structure of the Invention When the present inventors heated various metal materials in an ultra-high vacuum, they discovered that trace components contained inside the metal materials were concentrated (segregated, precipitated) on the surface. Furthermore, when a metal or alloy containing Ti and C is heated in a vacuum, TiC precipitates on the surface of the metal or alloy, and by applying pressure to alumina and heating it, or by applying pressure while heating, a solid phase is formed. It was found that it could be obtained by joining. The present invention was completed based on this knowledge.
本発明の要旨は、Ti及びＣを含有し、加熱す

囲気下で、加圧とTiCの析出を起こす温度以上の
加熱を行うことを特徴とする固相接合法にある。 The gist of the present invention is to heat a metal or an alloy containing Ti and C that precipitates TiC on its surface by heating it with alumina, under vacuum or an inert gas atmosphere, and pressurize the metal or alloy to a temperature that causes TiC to precipitate. The solid phase bonding method is characterized by performing the above heating.

気とする。 The metal or alloy containing Ti and C used in the present invention may be any metal as long as TiC can be precipitated on its surface by heating. Further, the atmosphere during pressurization and heating is a vacuum or an inert gas atmosphere.

る。 TiC precipitation usually occurs when heated above 750°C. On the other hand, since the adhesive strength is proportional to the contact area between the metal or alloy and alumina, the heating temperature is preferably such that the metal or alloy is slightly plastically deformed. Pressure may be applied using a normal pressure welding device, and a hot press, a HIP device, etc. can also be used.

る。 The method of the present invention can be used when alumina coating is too thin or when thick alumina is applied to the surface of a metal or alloy. Further, alumina can be bonded to each other by sandwiching a metal foil or metal powder containing Ti and C between the alumina and the alumina. Furthermore, a joining technique between an arbitrary base metal and a metal containing Ti and C,
By combining the bonding technology of the present invention between a metal containing Ti and C and alumina, alumina can be bonded to any base metal.
