Abstract

PURPOSE:To enable the separation of an interface or the cracks of a ceramic member to be removed effectively by fitting the ceramic member and metallic member via an intermediate member forming a honeycomb structure. CONSTITUTION:A ceramic member 1 being a cylindrical shape in its tip part and the tip part of the ceramic member 1 are fitted into a metallic member 2 from the outer periphery thereof via an annular intermediate member 3 consisting of Ti, Al or the like of a honeycomb structure, and the gaps of respective members are integrally adhered to each other by the method of brazing, welding or the like. The intermediate member 3 is a type wherein a metallic thin plate 7 is fabricated in a lattice shape and radially, and the inner peripheral side thereof is fabricated with a cylindrical plate 5 and the outer peripheral side thereof is fabricated with a cylindrical plate 6. Through this manner, the influence of residual stress in the joints can be softened more effectively.

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a ceramic-metal composite formed by fitting a ceramic member and a metal member through an intermediate member, and particularly relates to a ceramic-metal composite body that is formed by fitting a ceramic member and a metal member through an intermediate member, and particularly relates to a ceramic-metal composite body that is formed by fitting a ceramic member and a metal member through an intermediate member. For example, the present invention relates to a ceramic-metal composite having a structure suitable for joining a ceramic member and a metal member.

[Prior Art] Conventionally, methods for obtaining a bonded body by butting and gluing members with different coefficients of thermal expansion include methods of directly pressing and bonding the two, and providing a separate intermediate layer at the interface between the two. There are known methods of joining. For example, actual opening/closing 59-1
6053'' No. 1 discloses a method of bonding a ceramic and a metal by interposing a cladding material made of a W material or an MO material at the interface between the two.

[Problems to be Solved by the Invention] However, in the conventional method described above, residual stress was generated at the bonding interface due to the difference in thermal expansion, and a sufficient bonding strength could not be obtained.

In addition, when a clad material made of W material or MO material is used as the intermediate layer, the residual stress is removed to a certain extent compared to the case where the two are directly joined by a method such as pressure joining as described above. However, since the purpose of this intermediate layer is not to eliminate residual stress at the bonding interface, it has not been possible to eliminate peeling at the bonding interface or cracking of the ceramic member.

According to the present invention, there is provided a ceramic-metal composite body constructed by fitting a ceramic member and a metal member through an intermediate member, the intermediate member having a honeycomb structure. This can be achieved by using a ceramic-metal composite body characterized by the following.

In addition, in this ceramic-metal composite, it is preferable that the intermediate member is made lower toward the rigid fitting end, since the rigidity can be reduced in the portion where residual stress is more likely to remain.

[Function] The ceramic-metal composite of the present invention is constructed by fitting a ceramic member and a metal member through an intermediate member. Therefore, unlike a simple butt joint, the joint surface of the ceramic member and the metal member can be increased,
It can increase the bonding strength.

Furthermore, since the intermediate member has a honeycomb structure to reduce its rigidity, it absorbs the difference in thermal expansion between the ceramic member and the metal member that occurs when the temperature drops from the joining temperature to room temperature.
This eliminates the residual stress generated at the fitting end of the ceramic member, and does not deteriorate the adhesion between the members to be bonded.

以上の結果、接着性を犠牲にすることなく界面の剥離や

As a result of the above, it becomes possible to remove interfacial peeling and cracks in the ceramic member without sacrificing adhesiveness.

In addition, in a honeycomb structure as an intermediate member, if the rigidity is decreased toward the fitting end, for example, in the case of fitting between a cylinder and an annular body, the rigidity can be decreased toward the tip of the annular body of the cylinder. For example, it is more preferable to reduce the rigidity of a portion where residual stress tends to remain.
