Abstract

The present invention relates to method of preparing metal-base composite material. Aluminum metal powder and domestic garbage cinder with silica, alunina and silicon carbide as main components are mixed, pressed and liquid phase sintered to obtain aluminum-base composite material product. Under certain pressure and temperature conditions, one or several thermally stable reinforcing phases is created inside aluminum metal base via in-situ reaction, and the reinforcing phases is grains with high hardness and high high-temperature strength and dispersed via sintering to make the aluminum-base composite material possess high tensile elastic modulus, high hardness and high wear resistance. The present invention has low production cost and can reduce environmental pollution.

Description

[0001] 1. Technical Field: Composite Materials 2. Background technology:

[0002] The rapid development of modern science and technology has put forward higher and higher requirements for materials. The performance of metal matrix composites is superior to both metal materials and resin-based composites. Among them, particle-reinforced metal matrix composites are developed as heat-resistant, wear-resistant, and corrosion-resistant materials. It has good mechanical properties and friction properties. Generally speaking, metals and their alloys have good thermal diffusion properties and good ductility, but they are easy to oxidize and creep at high temperatures; ceramic particles are brittle, but have strong heat resistance and corrosion resistance. Combining the two materials together under certain process conditions, the composite material formed has the advantages of high strength, high hardness, high wear resistance, high corrosion resistance, high temperature resistance and...
