Problems solved by technology

The composite method of the composite material effectively solves the problem of ceramic particle prefabrication, and can ensure that the ceramic particles are evenly distributed in the matrix metal; the composite areas are not connected to each other, and at the same time, it can play a macroscopic shadow effect to enhance the wear resistance. The wear of the matrix metal is prevented; each composite area is nailed into the metal collective like a plum blossom pile, and the failure of one of the composite areas does not affect the continued use of the workpiece, effectively solving the problem of shedding of the surface composite material

Abstract

The invention relates to a preparation method of a quincuncial pile network distribution ceramic / metal composite material, and belongs to the technical field of metal-based composite material. A plurality of grooves are formed in a metal mesh through pressing. Then, ceramic particles are filled in the grooves of the metal mesh, and a sand casting mould is prepared according to the shape of the quincuncial pile network distribution ceramic / metal composite material to be prepared. The metal mesh filled with the ceramic particles is arranged on the upper surface of the mould cavity of the sand casting mould. Then a smelt metal substrate is poured in the sand casting mould. After the metal substrate is cooled, the metal substrate is stripped from the sand casting mould, and then the product is obtained. The preparation method can be used for effectively solving the problem on manufacturing a prefabricated body of ceramic particles and ensuring the uniform distribution of the ceramic particles in the metal substrate. All recombination regions are not connected with one another, and also can play a role of macroscopical shadow effect so as to strengthen the abrasion resistance, so that the abrasion of the metal substrate can be avoided, and the falling problem of a surface composite material can be solved effectively.

Description

technical field [0001] The invention relates to a preparation method of a plum-blossom pile network distributed ceramic / metal composite material, and belongs to the technical field of metal matrix composite materials. Background technique [0002] With the development of modern industry, the quality requirements of mechanical products are getting higher and higher, and the service conditions are becoming more and more demanding. In many industrial sectors such as metallurgy, electric power, and building materials, there are a large number of high-temperature abrasive wear conditions. The commonly used materials under these conditions have high melting points and good wear and corrosion resistance. However, since there is no anti-wear hard phase in these materials, their hardness is low and wear resistance is poor, resulting in huge friction and wear losses. With the development of materials science and technology, many scholars at home and abroad have tried to use different...
