本発明は多孔質セラミック部材の接合前処理方法に係シ
、特に多孔質セラミック部材を強固に接合することを可
能とする接合前処理方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a bonding pretreatment method for porous ceramic members, and more particularly to a bonding pretreatment method that enables porous ceramic members to be firmly bonded.

れている。In recent years, ceramic materials such as silicon carbide, silicon nitride, sialon, aluminum oxide, and zirconium oxide have attracted a lot of attention because of their excellent mechanical strength at high temperatures, as well as their excellent heat resistance and thermal shock resistance.
Gas turbine rotors, diesel engine cylinders,
Research and development is underway on numerous other high-temperature mechanical parts.

熱性、吸音性などの点にお（・て優れた特性を有すると
ころから広い範囲の応用が期待されている。Among ceramics, porous ceramic members are expected to be used in a wide range of applications because they have excellent properties such as heat insulation and sound absorption.
ところで通常、多孔質のセラミックス部材を用いて構造
部材を製作するには、製造工程においてセラミックス部
材同志あるいはセラミック部材と金属部材′とを確実に
接着させることがしばしば必要となる。In general, when manufacturing structural members using porous ceramic members, it is often necessary to reliably adhere the ceramic members to each other or the ceramic member and the metal member' during the manufacturing process.
一般に接着が行われる条件としては接着材によって被接
着物がぬれ接着材と被接着材とが良好に結合することが
必要である。しかるに多孔質のセラミックスはその表面
が極めてポーラスであるところから、接着材のセラミッ
ク部材接合予定表面への接着強度が低下し、これがため
に部材同志の結合強度も低（なるという問題がある。In general, the conditions for bonding are that the object to be bonded is wetted by the adhesive and that the bonding material and the material to be bonded are bonded well. However, since the surface of porous ceramics is extremely porous, the adhesive strength of the adhesive to the surfaces on which the ceramic members are to be joined is reduced, resulting in a problem that the bonding strength between the members is also low.

また、多孔質セラミック部材の接合予定面に金属モリブ
デンの粉末を付着した後加熱し、多孔質セラミック部材

案されている。As a method to solve this problem, it has been proposed to form a metal coating on the surface of the porous ceramic member to be joined using CVD (chemical vapor deposition), PVD (physical vapor deposition), thermal spraying, or the like. However, films formed by CVD or PVD are thin and are insufficient as a pretreatment method for bonding porous ceramic members. Although there is a thermal spraying method in which a molten powder substance is sprayed onto the surface of a member, there is a problem in that the inside of the pores of a porous ceramic member cannot be sufficiently filled. Furthermore, a method has also been proposed in which metal molybdenum powder is attached to the surface of the porous ceramic member to be joined and then heated to form a metal coating on the surface of the porous ceramic member to be joined.
しかるにこのような粉末を付着して溶着させただけでは
、多孔質セラミック部材の接合予定面が極めてポーラス
であるところがら溶着後の表面１、去極めて凹凸が多く
なシ、まｆＣ溶けた粉末がセラミック部材の孔に染み込
んだシして、均一で厚い膜を形成させることは難しい。However, if such powder is simply adhered and welded, the surface to be joined of the porous ceramic member is extremely porous, but the surface after welding is extremely uneven. It is difficult to form a uniform and thick film because it penetrates into the pores of the ceramic member.
