Materials, sliding members, etc., are required to have high temperature stability, sliding properties, and abrasion resistance.

In cases where the V value is high, metal-to-metal contact may cause adhesive wear, especially at high temperatures, and in such cases, the function of the two-legged parts may be impaired.

いは摺動速度・切削速度か変化するような部材に関して
は、また十分な信頼性か得られるには至っていない。For this reason, wear-resistant parts made of ceramic materials that have excellent wear resistance, heat resistance, and high temperature stability have been proposed. However, although such ceramic materials have excellent heat resistance and high-temperature stability, they have the disadvantage of low mechanical strength such as impact strength. There is a problem in that +lI cannot be used for members to which impact force is applied, and the fields in which it can be put to practical use are limited. Efforts have been made to improve the mechanical strength of ceramics in order to overcome some of the above drawbacks.Recently, the mechanical strength has improved considerably and the range of applications is expanding. It can also be applied to parts. However, sufficient reliability has not yet been achieved for members in which the direction of stress is not constant, or the sliding speed or cutting speed changes.
そこで、応力が集中するＪ、Ｉ；材部を金属材料で形成

に２層構造の耐摩耗性部品が提案されている（例えば、
特開昭６０１６６２７５号公報参照）。Therefore, a wear-resistant component with a two-layer structure has been proposed in which the J and I parts where stress is concentrated are made of a metal material, and the parts that require wear resistance are made of a ceramic layer (for example,
(Refer to Japanese Patent Application Laid-Open No. 60166275).

といった問題がある。[Problems to be Solved by the Invention] However, in such a wear-resistant component with a two-layer structure, the metal base material and the ceramic layer must be bonded, but the metal and ceramic have different chemical properties or Since the physical properties such as the coefficient of thermal expansion differ greatly, there is a problem in that it is difficult to firmly bond the metal base material and the ceramic layer.

なので、構造部品としての上のな信頼性を得ることがで
きないといった問題かある。For example, when a metal base material made of an iron-nickel alloy or the like and a ceramic layer mainly composed of Si3N+ are joined by brazing with a low-melting point material, the metal base material (4) can be joined at low temperatures. However, since the maximum bonding strength is about 20 to 30 kgf/n+m2, there is a problem that high reliability as a structural component cannot be obtained.

れる場合があるといった問題がある。On the other hand, when bonding a metal base material and a ceramic layer with a high melting point material such as tungsten carbide or cobalt,
Although the bonding strength is sufficiently increased, the high bonding temperature generates large thermal stress, causing bimetallic deformation between the metal base material and the ceramic layer, which not only does not function properly as a component, but also causes damage to the interface. In addition, high temperatures cause thermal deterioration of the metal base material made of iron-nickel alloy, etc., and its composition becomes coarser, reducing its strength. There is a problem that it may be destroyed.

It is an object of the present invention to provide a method for manufacturing a wear-resistant component having a ceramic layer, which can effectively prevent thermal deformation of a metal base material or deterioration of strength characteristics due to thermal deterioration.

The low melting point material set between the metal base material and the ceramic layer reacts with the metal base material to produce a low melting point alloy. The low melting point alloy produced in this manner melts at a relatively low temperature and provides a strong metallurgical bond between the metal base material and the metal compound material in the ceramic layer. On the other hand, since the metal compound material is formed integrally with the ceramic layer body, the metal base material and the ceramic layer are firmly joined via the low melting point alloy and the metal compound material.
また、接合温度を低くできるので、熱応力が小さくなり
バイメタル変形の発生を有効に防止できる。Furthermore, since the bonding temperature can be lowered, thermal stress is reduced and bimetal deformation can be effectively prevented.
かつ、金属製基（オの熱劣化による組成の粗大化を防止

を有効に防止することができろ。In addition, since it is possible to prevent the composition from becoming coarse due to thermal deterioration of the metal base material, it is possible to effectively prevent a decrease in the mechanical strength of the metal base material.
［実施例］ 以下、本発明の実施例を具体的に説明する。[Example] Examples of the present invention will be specifically described below.

Note that the metal compound material is not limited to the above composition, but may include WC-Co based TiC-C.

Then, such an assembly of the metal base material 6 and the ceramic layer 5 is heated at a temperature increase rate of 10° C./min while being pressurized at 10 kg/cm 2 .
以下、上記の方法で実際に加熱を行った結果を１説明す

耗性部品Ｐ、が得られた。When heating continued, the displacement meter (not shown) reached 1200℃.
There was a change. This indicates that a low melting point alloy portion 9 with a thickness of d has been formed from the low melting point material 7 and the metal base material 6, and that bonding between the metal base material 6 and the ceramic layer 5 has started. Therefore, we held the temperature at 1200℃ for 10 minutes,
After that, the pressurization was stopped and the mixture was gradually cooled down to 800° C. at a cooling rate of 2° C./min. As a result, a wear-resistant part P as shown in FIG. 1(g) was obtained.

であった。In the above-mentioned wear-resistant component P1, softening was observed in the vicinity of the bonding surface between the metal base layer 6 and the ceramic layer 5, but there was no softening at all in the pool area. The metal base material 6 and the ceramic 5 were firmly bonded, and the results of the shear test were also good.

耗性部品Ｐ１よりかなり劣っていた。For comparison, as shown in Figure 1 (h), a wear-resistant part was manufactured using the same manufacturing method as in the above example without using the low melting point material, and the temperature reached 1250°C. Until then, there was no change in the displacement meter. That is, the bonding temperature was 50° C. higher than in the above example. This temperature is slightly lower than the melting point of the Fe-Ni alloy with an N1 content of 36 wt%, which is the material of the metal base material 6.
This is the temperature at which the softening of the alloy occurs considerably. As shown in FIG. 1(i), in the thus obtained wear-resistant component P2, the entire metal scrap 6 was deformed due to thermal deterioration. In addition, the composition was coarser than before heating. Moreover, the results of the shear test were considerably inferior to the wear-resistant part P1 according to the present invention.

。(1) In a method for manufacturing a component having a ceramic layer on a metal base material, at least on the side to be bonded to the metal base material, C-Co, TiC-Co, or WC-Co-Ni that does not elute during sintering is used. system,
A silicon nitride-based material to which one or more of TiCN-Co-based metal compound materials is added is sintered to form a ceramic sintered body, and then the metal base is placed on a predetermined metal base material. After setting the low-melting point material that reacts with the material to form a low-melting point alloy during bonding, the ceramic sintered body is placed on the surface of the metal base material on the side where the low-melting point material is set, and the metal compound A method for producing a component having a ceramic layer, the method comprising: setting the ceramic sintered body so that the side containing the material faces a metal base material; and then joining the ceramic sintered body and the metal base material.
