METHOD FOR MANUFACTURING COMPOSITE MATERIAL OF SILICON CARBIDE PARTICLE-REINFORCED ALUMINUM-SILICON-BASED ALUMINUM ALLOY

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing a composite material of silicon carbide particle-reinforced aluminum-silicon-based aluminum alloy, in which wettability between silicon carbide (SiC) particles and aluminum alloy (Al) can be improved and ceramic particles with grain sizes of sub-microns from Nano-order can be compounded into aluminum alloy.;SOLUTION: The composite material of silicon carbide particle-reinforced aluminum-silicon-based aluminum alloy is obtained by: adding a silicon-based composite material with dispersed silicon carbide particles, to the molten aluminum or molten aluminum-silicon-based alloy; and then melting the silicon which is the matrix of the silicon-based composite material into the molten aluminum or the molten aluminum-silicon-based alloy. The silicon-based composite material is obtained by adding the silicon carbide particles to molten silicon or by mixing and forming the silicon carbide particles and the silicon particles and then firing the mixture of the silicon carbide particles and the silicon particles at the temperature more than the melting point of the silicon by heating them at a temperature more than the melting point of the silicon.;COPYRIGHT: (C)2013,JPO&INPIT
