本発明は、セラミック材料の接合方法においてセラミッ
クス表面のメタライズ部の構成に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a structure of a metallized portion on a ceramic surface in a method for joining ceramic materials.
セラミックーセラミック、セラミックー金属の接合にお

ミックス側から活性金属、活性金属と金属間化合物を形
成しない金属保護層とし、接合ロウ材の制約なしに十分
な接合強度が得られるようにした。In ceramic-ceramic and ceramic-metal bonding, the structure of the metallized part on the ceramic surface is made from the ceramic side with an active metal and a metal protective layer that does not form intermetallic compounds with the active metal, achieving sufficient bonding strength without the constraints of the bonding filler metal. I made it possible to obtain.
従来、活性金属を用いセラミックス表面をメタライズし
接合するとき、活性金属と金属間化合物を形成しない、
銀ロウ材を用いていた。Conventionally, when using active metals to metalize and bond ceramic surfaces, it is important to avoid forming intermetallic compounds with the active metals.
Silver solder was used.

性金属と金属間化合物を形成せず、十分な強度を得るこ
とを目的としている。Conventionally, when a ceramic surface is metallized using an active metal and then brazed directly, the problem has been that the strength of the joint is insufficient if a brazing material that forms an intermetallic compound with the active metal is used. Therefore, the object of the present invention is to solve these conventional drawbacks and to obtain sufficient strength without forming an intermetallic compound with the active metal even if a brazing material other than wax is used.
上記問題を解決するために、この発明は活性金属の表面
に活性金属と金属間化合物を形成しない金属保護層を配
置し、ロウ材の節約なしに接合強度の低下を防止するよ
うにした。In order to solve the above problem, the present invention arranges a metal protective layer that does not form an intermetallic compound with the active metal on the surface of the active metal, thereby preventing a decrease in bonding strength without saving brazing material.

性金属の接触を遮断するとともに、液相拡散によりロウ
材と結合し、強固な接合強度が得られる。When metallized ceramics having the above configuration are bonded using a brazing material, the ceramic and the metallized part are bonded by the active metal, and the active metal and the metal protective layer that does not form an intermetallic compound are bonded by diffusion, and the active metal and the metal are bonded by diffusion. A metal protective layer that does not form an intermediate compound blocks contact between the brazing material and the active metal, and is bonded to the brazing material by liquid phase diffusion, thereby providing strong bonding strength.

In the figure, an active metal 2 is placed on the surface of a ceramic 1.
A metal protective layer 3 that does not form an intermetallic compound with an active metal is provided thereon by means such as PVD or CVD, and is brazed with a metal material 5 using a brazing material 4 . With such a configuration, the active metal 2 and the brazing material 4 are
It is isolated by the metal protection N3 and cannot form intermetallic compounds. Therefore, even if a brazing material that forms an intermetallic compound with an active metal (for example, a brazing material mainly composed of gold) is used,
Unlike the conventional metallization shown in FIG. 2, since no intermetallic compound is formed, a bonding strength suitable for practical use can be obtained.
表2に、この発明のメタラズと従来のメタライズを金を
主成分とするロウ材で接合した場合の接合強度を示す。Table 2 shows the bonding strength when the metallization of the present invention and the conventional metallization were bonded using a brazing material containing gold as a main component.

食性を要求するものへも適用出来る。It is clearly seen that the bonding strength is improved by this invention. Furthermore, since it is possible to use a brazing material mainly made of gold, the corrosion resistance of the joint is much better than that of conventional joints using silver brazing material, making it suitable for use in items that require corrosion resistance in joints such as watch cases. Can be applied.

食性も向上するという効果がある。As explained above, in metallizing a ceramic surface, this invention provides a metal protective layer on the surface of an active metal, thereby making it possible to bond without forming an intermetallic compound even if any brazing material is used. This has the effect of preventing a decrease in bonding strength. Furthermore, since it is possible to use a brazing material mainly composed of gold, there is an effect that the corrosion resistance of the joint portion is also improved.
