采用电弧喷涂技术在Q345钢基体表面制备铝涂层，通过正交试验和极差分析发现影响铝涂层孔隙率的最主要因素是压缩空气压力和工作电流，而工作电压和喷涂距离对涂层孔隙率影响较小。同时优化出铝涂层在满足其他性能要求的同时孔隙率最小时的工艺参数为：压缩空气压力0.67 MPa，工作电流200 A，工作电压38 V，喷涂距离150 mm。

Arc spraying technology was used on the surface of Q345 steel substrate to prepare aluminum coating. By orthogonal test and range analysis, we found that the main influence effects to aluminum coating porosity was compressed air pressure and working current, while the working voltage and spraying distance had little influence on the porosity of the coating. Meanwhile the process parameters of minimum porosity were showed that:compressed air pressure was 0.67 MPa, working current was 200 A, working voltage was 38 V,and spraying distance was 150 mm.
