This invention relates to a method for manufacturing a wear-resistant composite material in which ZrO 2 , SiC, Si 3 N 4 ) is embedded.

が行われている。 Conventionally, high chromium cast iron, high manganese cast steel, high chromium cast steel, or low alloy steel has been used for the wear-resistant parts used in the above equipment.
In recent years, ceramics having wear resistance superior to that of cast iron or cast steel have been developed, and these materials have been used to manufacture wear-resistant parts for the above-mentioned equipment.

However, although ceramics have extremely excellent wear resistance, they are easily broken and have poor impact resistance, so multiple ceramics were embedded in a rubber plate with the surface exposed, and the wear resistance was improved. Composite materials have been developed to provide impact resistance, but since the substrate of such materials is made of natural or synthetic rubber, they cannot be used in areas that receive a certain amount of heat. There was a problem.

あつた。 Therefore, it is possible to manufacture a wear-resistant composite material by using a metal that can be used at higher temperatures than rubber for the substrate and exposing wear-resistant ceramics on the surface, but ceramics and metals do not expand due to thermal expansion. There was a problem in that it was difficult to arrange ceramics inside wear-resistant cast iron or wear-resistant cast steel because the coefficients and heat conduction coefficients were greatly different.

The purpose is to provide

A method for manufacturing a wear-resistant composite material according to the present invention that meets the above object is to produce a wear-resistant composite material in which the surface of a metal substrate is exposed with a gap between the holes of a metal base material having holes of a predetermined size on the surface. While the ceramic is fitted and held, the gap is filled with a self-fusing metal powder having a lower melting point than the metallic base and the wear-resistant ceramic, and then heated to melt the self-fusing metal powder to form the wear-resistant ceramic. is embedded and fixed in the metal base material.

の種類によつては真空中あるいは不活性ガス雰囲
気にて行われるのが好ましい。 Here, the metal base material filled with wear-resistant ceramics and self-fusing metal powder may be heated in air, but depending on the type of the metal base material and self-flux metal powder, heating may be performed in vacuum. Alternatively, it is preferable to carry out in an inert gas atmosphere.

The method for manufacturing a wear-resistant composite material according to the present invention includes:
A metal base material with holes of a predetermined size on its surface is made with a small gap between the holes, and the gap is filled with self-fusing metal powder and heated, so that only the self-fusing powder can be used. will melt and cover the gap.
この時、冷却の固定において金属性基材が収縮

よつてその締めつけ力が緩和され、セラミツクス
にひび等が入ることなく冷却される。 At this time, during cooling and fixation, the metallic base material contracts and tightens the internal ceramics, but the tightening force is relaxed by the molten or semi-molten self-fusing metal powder, causing cracks in the ceramics. It is cooled without entering.
そして、完全に冷却した状態においては自溶性
金属粉末がセラミツクスと金属性基材との接着剤
として働き、セラミツクスが強固に金属性基材中
に埋め込まれる。 Then, in a completely cooled state, the self-fusing metal powder acts as an adhesive between the ceramic and the metallic base material, and the ceramic is firmly embedded in the metallic base material.
続いて、添付した図面を参照しつつ本発明を具
体化した一実施例につき説明し、本発明の理解に

Next, an embodiment embodying the present invention will be described with reference to the attached drawings to provide an understanding of the present invention.

材料の断面図である。 Here, FIG. 1 is a plan view of a wear-resistant composite material to which the method of the present invention is applied, and FIG. 2 is a cross-sectional view of the wear-resistant composite material.
まず、第１図及び第２図に示すように、所定の

お、このセラミツクス１３は上記穴１０の内径よ

うになつている。 First, as shown in FIGS. 1 and 2, a thick plate material 11 is made of high chromium cast iron, which is an example of a metallic base material, in which holes 10 having a circular cross section of a predetermined size are provided at predetermined intervals. . Then, a small amount of self-fusing metal powder 12 is put into this hole 10, and a cylindrical ceramic 13 made of alumina or the like is charged. The ceramic 13 is made somewhat smaller than the inner diameter of the hole 10, so that there is a gap of about 1 to 2 mm.
また、自溶性金属粉末１２とはZn、Pb等の金
属単体を使用しても良いが、本実施例において
Niベースの成分によつて構成されている自溶性
金属を使用した。 Further, as the self-fusing metal powder 12, simple metals such as Zn and Pb may be used, but in this example,
A self-fusing metal composed of Ni-based components was used.

上部に重し１４を載せる。 Next, after charging the ceramics 13, the self-fusing metal powder 12 is charged into the gap again as shown in FIG. 2, and then placed in a heating furnace (not shown).
Place weight 14 on top.
ここで、重し１４をセラミツクス１３の上に載

うにする為であり、これによつてセラミツクス１
３を穴１０の所定の位置に固定することができ
る。 Here, the weight 14 was placed on the ceramics 13 using self-fusing metal powder 1 melted by heating.
This is to prevent the light ceramics 13 from floating on top of the ceramics 1.
3 can be fixed in place in the hole 10.
上記加熱炉によつて900〜1200℃に加熱すると、
自溶性金属粉末１２のみが溶解してセラミツクス

てセラミツクス１３を厚板材１１に固定する。 When heated to 900-1200℃ using the above heating furnace,
Only the self-fusing metal powder 12 melts and the ceramic 13 floats inside, and then by furnace cooling or air cooling, the molten self-fusing metal powder 12 solidifies and fixes the ceramic 13 to the thick plate material 11.
この時、高クロム鋳鉄からなる厚板材１１の冷

却することができ、これによつて耐摩耗性複合材
料１５が製造されることになる。 At this time, the hole 10 will contract as the thick plate material 11 made of high chromium cast iron cools, but since a layer of self-fusing metal powder 12 is formed inside, a direct compressive force is applied to the ceramic 13. It is relaxed and thus the ceramic 13 can be cooled without cracking, thereby producing a wear-resistant composite material 15.

角柱あるいは角錐台にすることも自由である。 In the above embodiment, the shape of the ceramic 13 and the hole 10 is cylindrical, but the shape is not limited to this, and the hole and the ceramic can also be formed into a tapered truncated cone with a small inclination angle. This completely prevents the ceramic from falling off, and furthermore, the ceramic can be freely formed into a prismatic or truncated pyramid.
また、上記実施例においてはセラミツクスを埋
め込む穴は有底としたが、下部まで貫通した孔と

れが良くなり、接着強度を強めることができる。 Furthermore, it is also possible to metallize the ceramic to form a metal coating on its surface, which improves wetting with the self-fusing metal powder and strengthens the adhesive strength.
