Method for preparing CuAl2O3 composite material through spray co-deposition reaction

The invention discloses a method for preparing CuAl2O3 composite material through a spray co-deposition reaction, which comprises the following steps: 1, processing of CuO powder; 2, preparation of alloy fusant; 3, preparation of CuAl/CuO alloy by the spray co-deposition; 4, preparation of CuAl2O3 composite material by carrying out in situ chemical reaction on the CuAl/CuO alloy; and 5, extrusion, rolling and drawing. The Al2O3 particle in the invention is synthesized by the in situ chemical reaction, has fresh reaction interface, is firmly matched with Cu, has nano-scale size, and obvious enhanced effect. The method of the invention has the characteristics of simple raw material preparation, excellent performance of the prepared materials, and easily controlled process; and the dispersion distribution of the wide phase of the composite material particle is completed by deformation through the process, and the problem of difficult subsequent process of the particle enhanced metal matrix composite is preferabl
