る。In recent years, means for improving the wear resistance and heat resistance of the entire part by employing a so-called fine ceramic part in combination with a part of a metal part or member subjected to severe wear or high heat has been adopted. The joint structure of metal and ceramics formed by such a combination is integrally joined with a metal intermediate layer between them, and the large difference in the coefficient of thermal expansion between the metal base material and ceramics is caused by the metal intermediate. After absorbing with a layer and joining by heating in an electric furnace of a metal base material and ceramics,
Thermal stress and thermal strain generated in the process of cooling at room temperature are alleviated, thereby preventing peeling at the joint surface.

いる。Conventional joining methods include, for example, the fourth method.
As shown in the figure, a metallized layer 2 is formed on the surface of a ceramic 1, a metal intermediate layer 3 is joined on the metallized layer 2, and this is put on a metal base material 4 via a brazing material 5. The two are integrally joined by heating. The metal intermediate layer 3 includes, for example, a Fe—Ni—Co alloy [Kovar,
Super Invar (trade name)] has a sandwich structure in which copper sheets 8 and 9 are sandwiched between brazing materials 7a and 7b, and a thermal expansion coefficient between the metal base material 4 and the ceramics 1 by the metal intermediate layer 3. The thermal stress is relaxed based on the difference between the two.

材４の接合面4aは、第４図に示すような一つの単純平面

もの接合面を持っていることが多い。Incidentally, the bonding surface 4a of the metal base material 4 to be coated with the ceramics 1 is not limited to one simple plane as shown in FIG. 4, but is generally a curved surface or a plurality of planes having different surface directions. For example, one metal base material often has several joint surfaces.

た。However, the conventional joining method, as described above,
Since the metallized layer 2 and the metal intermediate layer 3 were previously provided on the ceramics 1 and joined to the metal base material 4 in a vacuum with the brazing material 5 at a high temperature, for example, as shown in FIG. As shown in the figure, when the inner peripheral surface of a metal base material 10 having a U-shaped cross section is covered with ceramics 11, the bottom wall surface 12 of the metal base material 10 can obtain high-strength bonding, but the left and right side wall surfaces In the case of 13a and 13b, the brazing material 5 melted at the time of joining heating flows down, so that the brazing itself is difficult, and even if the brazing can be performed, the reliability is low.
そのため、従来にあっては金属母材10の接合面の形状
に制約があって適用範囲が狭くなってしまっていたり、
又は金属母材10を接合面毎に分割し、セラミックス11を
分割部材毎に接合した後に再び組み付けるなど煩雑な作
業を強いられる結果となっていた。For this reason, in the past, there were restrictions on the shape of the joining surface of the metal base material 10 and the application range was narrowed,
Alternatively, complicated work such as dividing the metal base material 10 for each joining surface, joining the ceramics 11 for each divided member, and then assembling the ceramics 11 again has been required.
そこで本発明の技術的課題は、方向の異なる二以上の
接合面を有する金属母材にセラミックスを接合する場合
に、簡易な手段により、しかも信頼性の高い接合強度を
持ち得る接合方法を提供するものである。Therefore, a technical problem of the present invention is to provide a joining method capable of having a highly reliable joining strength by simple means when joining ceramics to a metal base material having two or more joining surfaces in different directions. Things.
上記課題を解決するために、本発明に係る金属母材と

返し、前記接合面全域に前記セラミックスを接合するこ
とを特徴とするものである。In order to solve the above problems, a method for joining a metal base material and ceramics according to the present invention includes disposing ceramics on a metal base material having two or more bonding surfaces having different directions via a bonding auxiliary material. In a method of heating and joining in a heating furnace, one of the joining surfaces is horizontally arranged, and the operation of joining the ceramics to the horizontal joining surface is sequentially repeated to join the ceramics to the entire joining surface. It is characterized by the following.
また、金属母材セラミックスを接合する時の雰囲気温
度を、接合面の配置を変える毎に順次低くなるように調
整したことを特徴とするものが望ましい。In addition, it is desirable that the ambient temperature at the time of joining the metal base ceramics is adjusted so as to gradually decrease as the arrangement of the joining surface is changed.
上述の手段によれば、まず、接合面の一つに対して向

スを加熱接合して、次に、他の向きの接合面を水平にし
てセラミックスを加熱接合する操作を、全ての向きの接
合面に対して順次繰り返し、接合面全域にセラミックス
を接合する。According to the above-described means, first, the orientation is horizontally arranged with respect to one of the joining surfaces, and the ceramics of the joining surface that has been made horizontal are heated and joined, and then the joining surface in the other direction is made horizontal. The operation of heating and joining the ceramics is sequentially repeated for the joining surfaces in all directions, and the ceramics are joined over the entire joining surface.
これにより、一の面を加熱接合させた時に接合補助材
の一部が組成変化して溶融温度が上がり、次の面を加熱

といった不具合が生じることがなく、製造が容易になる
とともに製品品質が向上する。By this, when one surface is heated and joined, a part of the joining auxiliary material changes in composition and the melting temperature rises, and when the next surface is heated and joined, the joining auxiliary material on the previously joined surface is the same. Since it is difficult to melt at the joining temperature, even if the previous joining surface is arranged in the vertical direction, there is no problem that the joining auxiliary material melts out and the joined ceramics peels off It is easier and product quality is improved.
また、接合温度を順次低くなるように調整することに
よって、先に接合した面での接合補助材は更に溶融しに
くくなるので、接合強度の信頼性が一段と向上する。In addition, by adjusting the joining temperature so as to be gradually lowered, the joining auxiliary material on the previously joined surface is more difficult to be melted, so that the reliability of the joining strength is further improved.
以下添付図面に基づいて本発明の実施例を詳細に説明
する。Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
第１図乃至第３図は本発明の接合方法を示したもので
あり、断面コ字状の金属母材10の内側面、即ち底壁面12
およびこれと直交する左右の側壁面13a,13bにセラミッ
クスを接合する場合の例である。1 to 3 show a joining method according to the present invention, in which an inner surface of a metal base material 10 having a U-shaped cross section, that is, a bottom wall surface 12 is formed.
This is an example of a case in which ceramics are joined to left and right side wall surfaces 13a and 13b orthogonal to this.
まず、第１図に示すように、金属母材10を真空炉中の

属中間層３自体の接合を同時に行ってもよく、また金属
母材10への接合時には金属中間層３の接合は既に終了し
ていてもよい。First, as shown in FIG. 1, a metal base material 10 is placed on a pedestal 14 in a vacuum furnace such that a left wall surface 13a faces down, and a ceramic 11a is heated and joined to the left wall surface 13a. In this case, the metallized layer as a joining auxiliary material and the metal intermediate layer 3 are joined to the ceramics 11a in advance for each small piece, and the brazing material 5a as the joining auxiliary material is provided on the left wall surface 13a of the metal base material 10. Padding through, about 800-950 ° C in vacuum at 10
After heating for one minute, the brazing material 5a is melted and the ceramics 11a is integrally joined to the metal base material 10. The metal intermediate layer 3 is also made of Fe-N
The i-Co alloy and the copper plate sandwiching the i-Co alloy are joined by a brazing material. When joining with the metal base material 10, the metal intermediate layer 3 itself may be joined at the same time. At the time of joining, the joining of the metal intermediate layer 3 may be already finished.
上記のロウ材5aには、例えば銀ロウ（BAg−８）が用
いられ、600〜950℃溶融するといった特性を有する。従
って、約800〜950℃に加熱した場合にロウ材5aが十分に
溶融して金属母材10と金属中間層３との接合を可能にす
る。For example, silver brazing (BAg-8) is used as the brazing material 5a, and has a characteristic of melting at 600 to 950 ° C. Therefore, when heated to about 800 to 950 ° C., the brazing material 5 a is sufficiently melted to enable joining of the metal base material 10 and the metal intermediate layer 3.
一方、このロウ材5aの溶融時に、これと接する金属中

干変化させ、ロウ材5aの融点を高める。因みに同の融点
は1083℃である。On the other hand, when the brazing material 5a is melted, the metal intermediate layer 3 in contact with the brazing material, specifically, the copper plate 9 shown in FIG. 4 partially diffuses into the brazing material 5a, and reacts with the brazing material 5a to cause the diffusion. The composition is slightly changed to increase the melting point of the brazing material 5a. Incidentally, the same melting point is 1083 ° C.
上述の接合が終了したら、次いで第２図に示すよう

ために、ロウ材5aが流れ出したり、また一旦接合したセ
ラミックス11aの小片が剥れ落ちるといった不都合がな
い。After the above-mentioned joining is completed, as shown in FIG. 2, the metal base material 10 is rotated by 90 ° and placed on the pedestal 14 so that the bottom wall surface 12 is horizontal. Are joined by heating. In this case as well, the brazing material 5b in contact with the bottom wall surface 12 is melted by heating to substantially the same temperature as before,
Since the brazing material 5a which has already joined the ceramics 11a on the left side wall 13a has a composition change as described above and has a slightly higher melting temperature than the brazing material 5b on the bottom wall 12, There is no inconvenience that the brazing material 5a flows out and small pieces of the ceramics 11a that have been joined once come off.
底壁面12での接合が終了したら、更に第３図に示すよ
うに、金属母材10を90゜回転させて右側壁面13bが下に

材5bは一部組成変化していて溶融温度が高くなっている
ため、左側壁面13aを含めてロウ材5bが流れ出すといっ
たことがなく、セラミックス11bの剥離を確実に防止し
得る。After the joining at the bottom wall surface 12 is completed, the metal base material 10 is further rotated by 90 ° to arrange the right wall surface 13b downward as shown in FIG. Ceramic pieces are spread, and the ceramics 11c are heated and joined at substantially the same temperature. And also in this case, since the brazing material 5b on the bottom wall surface 12 partially changes in composition and the melting temperature is high, the brazing material 5b including the left side wall surface 13a does not flow out, and the ceramics 11b Peeling can be reliably prevented.
このように本実施例によれば、コ字状断面をなす金属
母材10の内側面に強度的に信頼性の高いセラミックス11
の接合を比較的簡易な手段で行なうことができることに
なり、上述の金属母材10のような３つの接合面に限られ

ることになる。As described above, according to the present embodiment, the ceramic 11 having high strength and reliability is provided on the inner surface of the metal base material 10 having the U-shaped cross section.
Can be performed by relatively simple means, and the present invention is not limited to the three bonding surfaces such as the metal base material 10 described above, and can be bonded to the bonding surfaces having more complicated shapes by the same means. .
また、上記実施例では、３つの接合面を全て同じ温度
で加熱接合したが、接合面の配置を変える毎に順次温度
が低くなるように調整し、先の接合面での接合温度より
若干低い温度で加熱接合することにより、信頼性はより
一段と向上する。Further, in the above embodiment, all three bonding surfaces were heated and bonded at the same temperature. However, each time the arrangement of the bonding surfaces was changed, the temperature was sequentially adjusted to be lower, and was slightly lower than the bonding temperature at the previous bonding surface. By performing the heat bonding at the temperature, the reliability is further improved.

の場合、最初に接合する接合面での加熱温度がロウ材の
溶融温度を上回るように温度調整する必要がある。According to the above embodiment, the metal base material 10 to be joined first
When the left side wall 13a is heated and joined at 900 to 950 ° C., the bottom wall 12 is at 850 to 900 ° C.
b is the one to be heated and joined at 800 to 850 ° C. In this case, it is necessary to adjust the temperature so that the heating temperature at the joint surface to be joined first exceeds the melting temperature of the brazing material.
上記ロウ材５には、銀ロウ材（BAg−８）の他に、り

接合）を850〜900℃で行、第二の接合（金属母材の底壁

の右側壁面の接合）を750〜800℃で行うことにより、ロ
ウ材が流出することのない強度の大きさ接合を得ること
ができる。一方、ニッケルロウ材は900℃〜1050℃の間
で溶融するので、例えば第一の接合を1000〜1050℃で、
第二の接合を950〜1000℃で、第三の接合を900〜950℃
でそれぞれ行うことで確実な接合を得ることができる。As the brazing material 5, a phosphor copper brazing material or a nickel brazing material can be used in addition to the silver brazing material (BAg-8).
Since the phosphor copper brazing material is in a molten state between 700 and 950 ° C. and can be used, for example, in the case of joining ceramics in the above embodiment, the first joining (joining of the left wall surface of the metal base material) is performed. Perform at 850-900 ° C, perform the second joining (joining the bottom wall of the metal base material) at 800-850 ° C, and perform the third joining (joining the right wall surface of the metal base material) at 750-800 ° C This makes it possible to obtain a high-strength joint that does not allow the brazing material to flow out. On the other hand, since the nickel brazing material melts between 900 ° C and 1050 ° C, for example, the first joining is performed at 1000-1050 ° C,
Second bonding at 950-1000 ° C, third bonding at 900-950 ° C
By doing so, reliable bonding can be obtained.

It can be applied to any material-based ceramics.
また、上記実施例では、ロウ材5a,5b,5cと接触する金
属中間層３は銅板９であるが、必ずしもこに限定される

銀や、銅又は銀を含む合金なども用いることができる。Further, in the above embodiment, the metal intermediate layer 3 in contact with the brazing materials 5a, 5b, 5c is the copper plate 9, but it is not necessarily limited to this, and the metal intermediate layer 3 is made of a highly ductile metal having the same properties as copper. Silver or an alloy containing copper or silver can also be used.

ることができる。As described above, according to the method for bonding a metal base material and ceramics according to the present invention, ceramics are arranged on a metal base material having two or more bonding surfaces in different directions, and these are heated and bonded in a heating furnace. If you do, for each joint surface,
One of the joining surfaces is placed horizontally and the ceramics are joined by heating, and then the operation of heating and joining the ceramics with the joining surfaces in the other direction horizontal is sequentially repeated for the joining surfaces in all directions As a result, the ceramics are joined to the entire joining surface, so that when the joining auxiliary material on the surface joined first heats and joins the ceramics, a part of the joining auxiliary material changes in composition and the melting temperature rises. When the joint surfaces are heated and joined together, the auxiliary joining material of the previously joined surface becomes difficult to melt at the same joining temperature, so that the joining auxiliary material does not flow out regardless of the orientation of the previously joined surface, making it simple. Since a highly reliable bonding strength can be obtained by a simple bonding method, the applicable range can be dramatically expanded.

向上させることができる。Also, by adjusting the temperature of the atmosphere to be subsequently heated and joined so as to be lower sequentially than the temperature of the atmosphere to be heated and joined earlier, when the subsequent joining surface is to be joined by heating, the joining auxiliary material at the joining surface joined earlier is used. Is difficult to melt at the same bonding temperature, so the direction of the previous bonding surface changes, and even if it is arranged vertically, the bonding auxiliary material of the previous bonding surface melts during heating bonding to the subsequent bonding surface. The jointed product of the metal base material and the ceramic can be easily manufactured, and the quality of the product can be improved without causing a problem that the ceramics come out and the bonded ceramics come off.
