本発明はセラミックス部材と金属部材の結合方法に関す

いた。(Prior art) Conventionally, when joining ceramics and metal by shrink fitting, a cylindrical metal member is heated and expanded, and a shaft-shaped ceramic member at room temperature or cooled is fitted into the cylindrical metal member in that state. By cooling, a strong bond was obtained between the two members.

なりその加工が難しい欠点もあった。(Problems to be Solved by the Invention) However, in the conventional shrink fitting method described above, when used as an engine member exposed to high temperature and pressure, the bonding ability between ceramic and metal is limited due to loosening of the tightening parts. However, there were drawbacks such as gas leakage due to surface irregularities and cracks occurring due to uneven contact conditions. Also,
Since the amount of tightening after shrink fitting varies depending on the processing conditions of both members before joining, a processing dimensional accuracy of 10 μm or less is required, which also has the drawback of being difficult to process.

である。The purpose of the present invention is to eliminate the above-mentioned problems, prevent the combined okara gas from leaking even when used under high temperature and high pressure, and provide an appropriate thickness to the brazing material to provide a contact area between both parts. The purpose of the present invention is to provide a method for joining ceramic members and metal members that can alleviate the concentration of strain stress and torsional stress of the ceramic member and does not require high processing dimensional accuracy before joining.
（問題点を解決するための手段）
本発明のセラミックス部材と金属部材の結合方法は金属
部材を該金属部材より熱膨張係数が小さいセラミックス
部材の外側に配置し、加熱下で両者間に所定の隙間を生
じせしめた状態で、該隙間中に溶融したろう材を浸透さ
せた後、冷却固化することを特徴とする。(Means for Solving the Problems) The method of joining a ceramic member and a metal member of the present invention is to arrange the metal member outside the ceramic member whose coefficient of thermal expansion is smaller than that of the metal member, and to create a predetermined gap between the two under heating. The method is characterized in that a molten brazing filler metal is infiltrated into the gap with a gap formed therein, and then cooled and solidified.
（作 用）
上述した構成において、金属部材をこれより熱膨張係数

結合部上端にろう材を設置する。(Function) In the above-described configuration, after the metal member is placed outside the ceramic member whose coefficient of thermal expansion is smaller than that of the metal member, a brazing material is placed at the upper end of the joint between the metal member and the ceramic member.

め付方のばらつきをなくすことができる。By heating both to a temperature higher than the melting point of the brazing material, a gap is created between the two, and the molten brazing material penetrates into this gap. Thereafter, when both members are cooled and solidified, the ceramic member and the metal member are firmly joined by the outer metal member tightening the inner ceramic member through the brazing filler metal, producing a so-called shrink fit effect. Even when the bonded body obtained by the bonding method of the present invention is exposed to high temperature and high pressure, the brazing material between the two members acts as a cushion and they are in even and close contact, so there is no strain stress or torsion without gas leakage. This makes it possible to reduce the stress caused by the process and eliminate variations in the tightening method after joining without having to control the machining dimensional accuracy of both members so strictly before joining.

方法である。(Effects of the Invention) As is clear from the above detailed explanation, according to the method of joining a ceramic member and a metal member of the present invention, a brazing material is inserted between the ceramic member and the metal member during joining. As a result, gas will not leak from the joint even when the joint is used under high temperature and high pressure, and by giving the brazing filler metal an appropriate thickness, the contact area between the two parts will be reduced. Concentration of strain stress and torsional stress can be alleviated. In addition, it is possible to eliminate variations in the tightening force after joining without having to strictly control the machining dimensional accuracy of both parts before joining, and because commercially available brazing filler metal can be used without using special equipment, it is an inexpensive method. Easy to manufacture at low cost. The present invention is an industrially extremely useful method that can be used as a method for manufacturing gas turbine parts such as ceramic rotors, turbine blades, and nozzles, and engine parts such as ceramic cylinders, pistons, hot plates, and valves.
