摘　　要：在LED用Al-Mg-Si系铝合金表面制备阳极氧化膜,讨论工艺参数对膜层厚度和硬度和耐腐蚀性的影响.得到工艺优化参数如下:硫酸浓度为120g/L,复合添加剂用量为20g/L,溶液温度20℃,直流电压为21V,氧化时间40 min.优化条件下得到的阳极氧化膜厚度为37μm,耐腐蚀性能指标为182s,硬度为379HV.The anodic oxidation films were prepared on the surface of Al- Mg- Si aluminum alloy used for LED production and the effects of different parameters on the thickness,hardness and corrosion resistance of the films were discussed. The optimized parameters were obtained as follows： the concentration of H2SO4 was 120 g / L,the concentration of composite additive was 20 g / L,the solution temperature was 20℃,the voltage of direct current was 21 V,and the oxidation time was 40 minutes. The thickness,corrosion resistance and hardness of the anodic oxidation film under optimum conditions were 37μm,182 s and 379 HV,respectively.
