Abstract:
The copper-based bulk materials were prepared by low-pressure cold spray additive manufacturing technology. The thermal conductivity and mechanical properties of the bulk materials were tested. The cross-section and tensile sections of the bulk materials were observed and analyzed by means of SEM. The results show that the thermal conductivity of copper-based bulk materials prepared from copper-based powders with a volume ratio of 10% Al2O3 is better. With the increase of Al2O3 content, the thermal conductivity decreases. After annealing, the cold-sprayed copper-based bulk material has improved thermal conductivity and mechanical properties. The thermal diffusivity and tensile strength show a trend of increasing first and then decreasing with the increase of annealing temperature. When the annealing temperature is 500℃, the thermal diffusivity of the heat-treated copper-based bulk material is 80.43% of the processed copper bulk material,the tensile strength is 125.3 MPa.
