(Field of Industrial Application) The present invention relates to a method for manufacturing a composite material having excellent wear resistance and toughness, in which a wear-resistant surface layer is integrated on the surface of a steel base material having excellent toughness. (Prior art) In general, wear resistance and toughness are contradictory properties, so a material with excellent both properties has not yet been developed. Materials with excellent wear resistance, such as high chromium white cast iron, Toughness is significantly inferior. However, parts that require not only wear resistance but also toughness, especially
There are many parts in which only the wear surface that slides or rubs against other parts is required to have wear resistance, while the base part is required to have toughness. Therefore, many products have been developed in which the base part is made of a metal with excellent toughness and the surface layer is made of a wear-resistant material using the cast-in method, high-pressure infiltration method, or adhesive method. However, it was difficult to say that the results were satisfactory as there were many restrictions. In order to solve these problems, an invention has been developed in which wear-resistant particles are set in a layer on the cavity surface of the lower mold, and molten metal is poured while the particles are sucked by suction pressure applied to the cavity surface. A method for producing a composite material in which the molten metal is allowed to penetrate between abrasive particles was previously proposed in Japanese Patent Application Laid-open No. 121735/1983. (Problems to be Solved by the Invention) However, in the method described in the above publication, there are many problems such as poor penetration of the molten metal between the wear-resistant particles and a lack of adhesive strength between the wear-resistant particles and the molten metal. However, this problem remained, and there were many cases where the wear-resistant particles were not firmly integrated onto the surface of the metal base material. (Means for Solving the Problems) The present invention aims to provide a method for manufacturing a composite material with excellent wear resistance and toughness that solves the above-mentioned problems. Wear-resistant particles and Ni-based metal particles melted by the poured molten metal are set in layers on the cavity surface, and these are sucked by the suction pressure applied to the cavity surface, and then steel is placed in the mold. Molten metal is poured and the metal particles are melted by the heat of the molten metal, and the molten metal and the steel molten metal are mixed and penetrated between the wear-resistant particles by the suction pressure to form a steel base material with excellent toughness. A composite material with excellent wear resistance and toughness characterized by casting a composite material having a wear-resistant surface layer in which the wear-resistant particles are firmly integrated with an alloy of the Ni-based metal and steel on the surface. The first invention is a method for manufacturing a composite material, in which a mixed layer of wear-resistant particles and Ni-based metal particles melted by poured molten metal is layered on the cavity surface of the lower mold of a pair of upper and lower molds. After setting the mold to the mold and drawing it in by suction pressure applied to the cavity surface, molten steel is poured into the mold, and the metal particles are melted by the heat of the molten metal, and the molten Ni
The Ni-based metal and the molten steel are mixed and infiltrated between the wear-resistant particles by the suction pressure, and the alloy of the Ni-based metal and steel is applied to the surface of the steel base material having excellent toughness. The second invention is a method for manufacturing a composite material having excellent wear resistance and toughness, which is characterized by casting a composite material having a wear-resistant surface layer in which abrasive particles are firmly integrated. In the present invention, as the wear-resistant particles set in a layer on the cavity surface of the lower mold of a pair of upper and lower molds, metal particles or ceramic particles with excellent wear resistance are used alone or in a mixture of both. First, a lower mold 2a as shown in FIG. 1 or as shown in FIG. A layer 3 made of wear-resistant particles is formed by setting wear-resistant particles in a layered manner to a desired thickness on the cavity surface of a lower mold 2c used in a vacuum molding method. In this case, the Ni-based metal particles 4, which are easily melted by the heat of the molten steel that is poured later and which increases the strength of the steel, are made of wear-resistant particles as shown in Figures 1 and 3. Set it in a thin layer on the surface of layer 3. Note that such Ni-based metal particles 4 are not formed in a layered manner on the surface of the layer 3 made of wear-resistant particles as described above, but in the second layer.
As shown in the figure, a mixed layer of wear-resistant particles and Ni-based metal particles 4 may be set on the cavity surface of the lower mold 2b in a layered manner to have a desired thickness. Next, a plastic film 5 is covered as necessary so that suction pressure can effectively act on the surface of the above-described layer, and an upper mold 6a is formed so that the suction action can be applied to the openings of the lower molds 2a, 2b, and 2c. ,6b,6
c, and by reducing the pressure inside the upper and lower molds and applying suction pressure to the cavity surface, layer 3 made of wear-resistant particles and a mixed layer of wear-resistant particles and Ni-based metal particles 4 are formed on the cavity surface. In this state, molten steel is poured from the sprue 7 to melt and vaporize the plastic film 5, and then brought into contact with the layer to which suction pressure is applied, to form self-soluble Ni-based metal particles. 4 is melted together with the molten steel by the molten steel and latent heat of solidification, and mixed and penetrated between the wear-resistant particles. When these are cooled, the molten steel hardens and becomes a steel base material with excellent toughness, and the wear-resistant particles are firmly integrated by an alloy of the molten Ni-based metal and the molten steel, which penetrate into each other. The metal structure shown in the micrograph at 10x magnification in Figure 4 or Figure 5 shows that the surface of a steel base material with excellent toughness is precisely integrated with the steel base material, and that it is larger than the steel base material. The alloy of strong steel and Ni-based metal results in a composite material having a wear-resistant surface layer in which wear-resistant particles are firmly integrated. Example 1 Using the mold shown in Figure 1, particles from 2000 μm in diameter
After setting a layer of 27% chromium cast iron particles of 3000μm on the cavity surface of the lower mold, the particle size is approximately 50μm.
17%Cr, 4%Fe, 4%Si, 3.5%B, 1.0%C,
After setting a thin layer of Ni-based alloy particles with the balance being Ni, molten high manganese steel was poured into the casting to create a cast product, which was then heat treated with forced air cooling from 1000°C. The results were obtained by comparing the wear resistance of high manganese steel, 27% chromium cast iron, and example samples using an endless abrasive belt with an alumina grain size of #40 at a load of 218 g/cm 2 and a circumferential belt speed of 8 m/sec. is table 1

ある。[Table] (Effects of the Invention) As is clear from the above description, the present invention is a material that does not have the disadvantages caused by the manufacturing method, which has conventionally been difficult to obtain materials with excellent wear resistance and toughness. This makes it possible to relatively easily cast a wear-resistant composite material that has not yet been obtained.
Rather than integrating wear-resistant particles with only molten steel, we provide a double layer surface of wear-resistant particles and Ni-based metal particles or a mixed layer of wear-resistant particles and Ni-based metal particles. After that, molten steel is poured, and an alloy in which the molten steel and Ni-based molten metal penetrate and mix is interposed between the wear-resistant particles, and the wear-resistant particles are united with this alloy. , the adhesion between the wear-resistant particles and the integrity with the steel base material are extremely good, making it easy to obtain an excellent wear-resistant surface layer. In other words, alloys of Ni-based metals and steel not only increase strength while retaining the characteristics of steel, but also have better permeability between wear-resistant particles when melted than molten steel, making it possible to apply suction pressure to the cavity surface. When cast while adding, the wear-resistant particles penetrate into the gaps between each other without any gaps and are accurately integrated with the base steel, and the wear-resistant particles do not mix loosely into the cast steel. This method has the following advantages and will greatly contribute to the development of the industry as a manufacturing method for composite materials with excellent wear resistance and toughness that have a wide range of uses.
