受材として利用する研究が盛んに行われている。Conventional Technology In recent years, much research has been conducted on the use of ceramics, which have excellent wear resistance and mechanical strength, as the sliding parts of automobile engines such as tappets, cams, and rocker arms, as well as high-speed bearing materials and bearing materials for gas turbines. ing.
セラミクスを摺動部等に使用することにより、耐摩耗性

することができるからである。This is because by using ceramics for sliding parts and the like, it is possible to expect not only wear resistance but also weight reduction of the moving parts and, ultimately, improved efficiency.
このように従来金属であった機械部品をセラミクスに置
き代える傾向が高まるに連れ、いくつかの問題点が明ら
かになった。As the trend toward replacing traditionally metal mechanical parts with ceramics increases, several problems have become apparent.
すなわち、セラミクス部品は成形後焼結されさらに切削

加工が難しくなるという欠点があること。さらに、セラ
ミクス部品を一体成型物とすると加工の際、切削量が多
くなり製品のコストが非常に高くつくという問題がある
こと等である。In other words, ceramic parts are molded, sintered, and then processed through cutting and other processing to produce products. However, ceramics generally have low reliability in terms of strength, especially toughness, which makes design and processing difficult. Furthermore, when ceramic parts are integrally molded, there is a problem in that the amount of cutting increases during processing, making the cost of the product extremely high.
このため、摩耗面を有する部品において摩耗面以外の部

摺動部などの摩耗面にセラミクスチップを接合させた部
品が開発されつつある。For this reason, low-cost sintered metal members are used in parts other than the wear surface of parts that have wear surfaces, as in the past.
Parts in which ceramic chips are bonded to wear surfaces such as sliding parts are being developed.

できないという問題があった。In order to join and integrate a ceramic member and a sintered metal member, it is necessary to use a brazing material, etc., but in this case,
There was a problem in that sufficient bonding could not be achieved because the filler metal flowed into the pores of the sintered metal.
また、セラミクスと金属とは一般に熱膨張性が著しく異

ミクスが割れることがあった。Additionally, ceramics and metals generally have significantly different thermal expansion properties and are difficult to blend with each other, so if the combination of the two is inappropriate, the ceramics may crack due to thermal stress generated during bonding.

本発明は、焼結金属とセラミクスとの接合体を製造する
際、予め焼結金属の接合部表面に表面の空孔を充填する
ように被覆材による被覆層を形成させ、セラミクスの接
合面をメタライズ処理し、接合用゛ろう材として低融点
ろう材を使用することに主な特徴がある。In the present invention, when manufacturing a bonded body of sintered metal and ceramics, a coating layer is formed in advance on the surface of the bonded part of the sintered metal with a coating material so as to fill the pores on the surface, and the bonding of the ceramics is improved. The main features are that the surface is metallized and a low melting point brazing material is used as the joining brazing material.
焼結金属の空孔を充填し、被覆層を形成させる被覆材と

込み易くなるため、空孔を良好に充填、被覆層を形成す
るからである。The coating material that fills the pores of the sintered metal and forms the coating layer is preferably a Mn-N 1-Cu alloy. this is,
It is difficult to fill the pores of the sintered metal and form a coating layer with a general brazing filler metal, but the Mn-Ni-Cu alloy has good wettability with the sintered metal, and it is also difficult to sinter during heat treatment. This is because it reacts with the compacted metal and becomes viscous, making it easier to flow into the pores, thereby filling the pores well and forming a coating layer.

う材との接着性も悪化するためである。The composition of the Mr+-N+-Cu alloy includes 5 to 70% by weight of Mn, 5 to 70% by weight of Ni, and 5 to 70% by weight of Cu, and the total of Mn, Ni, and Cu is 50% by weight of the total amount of the alloy. 1%
It is preferable that it is above. This is Mn-N 1-Cu
If the composition of the system alloy and the total amount of Mn5Ni and Cu in the total amount of the alloy are out of the above range, the alloy will not react with the sintered metal, and the viscosity during heat treatment will be inappropriate, resulting in insufficient penetration into the pores. This is because the pores are not completely filled and the adhesion with the joining brazing material is also deteriorated.
上記のようにＭｎ−Ｎ １−Ｃｕ系合金で、焼結金属の
接合面の空孔を予め充填するとセラミクスと焼結金属部
材を接合する際に、ろう材が焼結金属の空孔内に侵入す

な接合部を形成するため焼結金属とセラミクスとは十分
な接合強度をもって固着する。As mentioned above, if the pores on the joint surface of the sintered metal are filled with the Mn-N 1-Cu alloy in advance, the filler metal will fill the pores of the sintered metal when joining the ceramic and sintered metal member. The sintered metal and ceramics are firmly bonded to each other with sufficient bonding strength because the coating layer and the bonding brazing filler metal do not penetrate and form a strong bond.
本発明に従うと、セラミクスの接合面は予めメタライズ
処理されていることが好ましい。この処理により、接合
用のろう材との密着性が向上し、接合強度が上がる。According to the present invention, the bonding surface of the ceramics is preferably metallized in advance. This treatment improves the adhesion with the brazing filler metal for bonding and increases the bonding strength.

なわち、融点が３００℃以下の低融点ろう材を用いた場
合の熱応力は、接合強度と比較した場合、はとんど問題
にならない程度の大きさとなる。Further, according to the present invention, a low melting point brazing material having a melting point of 300° C. or lower is used for joining. The reason for this is that the thermal expansion coefficients of metals and ceramics are significantly different, so stress is generated and remains during thermal cycles during bonding, which may reduce bonding strength or make bonding difficult. However, these problems can be solved by using a low melting point brazing filler metal with a melting point of 300° C. or lower. That is, when a low melting point brazing filler metal with a melting point of 300° C. or less is used, the thermal stress is so large that it hardly becomes a problem when compared with the bonding strength.
上記の接合用低融点ろう材としては、５ｎ−Ｐｂ系のろ
う材が、信頼性、コスト両面から好ましい。As the above-mentioned low melting point brazing filler metal for joining, a 5n-Pb based brazing filler metal is preferable in terms of both reliability and cost.
また、本発明の接合体に用いる焼結金属は、充填、被覆
材に用いるＭｎ−Ｎ １−Ｃｕ系合金と良好に反応する
、Ｆｅ系合金またはＣｕ系合金が好ましい。Further, the sintered metal used in the joined body of the present invention is preferably an Fe-based alloy or a Cu-based alloy, which reacts well with the Mn-N 1-Cu-based alloy used for the filling and coating material.

用する機械の耐久性も向上する。By using the strongly bonded sintered metal-ceramic bonded body of the present invention in parts that require wear resistance, such as engine parts such as cams, tappets, and rocker arms, it is possible to use This improves wear resistance and reduces weight compared to conventional parts, and also improves the durability of machines that use such parts.
