Different volume ratios of Al2O3 powder and copper powder are mixed, and a copper-based composite coating is prepared on a pure copper matrix by low-pressure cold spraying technology.The hardness and bond strength of the coating were tested, and the cross-section of the coating was observed and analyzed with a field emission scanning electron microscope. The effect of Al2O3 content in the original powder on the coating performance was investigated.The experimental results show that the copper-based composite coating prepared from copper powder with a particle size range of 10-40μm has a lower porosity and a denser coating structure.With the increase of the content of Al2O3 in the original powder, both the microhardness and the bond strength of the coating showed a law of increasing first and then decreasing. When the content of Al2O3 was 20%, the coating had the best performance.
