Three types of aluminum alloy powder were mixed with the Al-based metallic glasses powder in different proportions, and the Al-based metallic glasses composites were prepared by cold spraying. The microstructure of the coatings was investigated, and the compressive strength of the Al-based metallic glasses composites was tested. Numerical simulation was carried out to study the formation of the composite coatings. The porosity of the composite coatings was significantly lower than for the Al-based metallic glasses coating. The maximum compression strength was 584 MPa when adding 50% Al7075 powder, and the compressive strength of Al-based metallic glasses composites has a positive correlation with the types of added aluminum alloy powder. The grinding effect due to the relative slip between the Al-based metallic glasses particles and the soft particles was observed at the fracture surface. The Al-based metallic glasses particles were packed closely with the surrounding Al7075 particles after fracture. Simulation results showed that the soft particles behaved like a droplet when impacted onto the metallic glasses particles, and gaps between the metallic glasses particles were filled with soft particles, but some pores still existed when adding Al7075 powder due to its relatively higher strength.

将三种铝合金粉末与铝基金属玻璃粉末按不同比例混合，冷喷涂制备铝基金属玻璃复合材料。研究了涂层的微观结构，并测试了铝基金属玻璃复合材料的抗压强度。通过数值模拟研究了复合涂层的形成。复合涂层的孔隙率明显低于铝基金属玻璃涂层。添加50%Al7075粉末时的最大抗压强度为584 MPa，Al基金属玻璃复合材料的抗压强度与添加的铝合金粉末种类呈正相关。在断面上观察到由于铝基金属玻璃颗粒与软质颗粒之间的相对滑移而产生的磨削效果。Al基金属玻璃颗粒在断裂后与周围的Al7075颗粒紧密堆积。模拟结果表明，软质颗粒撞击金属玻璃颗粒时呈液滴状，金属玻璃颗粒之间的间隙被软质颗粒填充，但添加Al7075粉末后，由于其强度较高，仍存在一些孔隙。
