摘　　要：选用ZL102合金作为一种新型封装基板的中间镀层进行阳极氧化试验,制备厚的多孔层阳极氧化膜。研究了电解液、电流密度、温度、时间对阳极氧化膜的形貌特征、孔隙率、厚度、硬度、耐压性和热阻性能的影响,得到了综合性能最佳的厚膜实验条件。结果表明:ZL102铝合金在不同的电解液(硫酸、硫酸-草酸、硫酸-酒石酸、硫酸-柠檬酸)、电流密度(2~6 A/dm^(2))、温度(10~30℃)、时间(80~160 min)下均能形成颜色均一、表面光滑的氧化膜。综合性能最佳的厚阳极氧化膜的工艺条件为:硫酸-草酸为电解液,电流密度6 A/dm^(2),温度15℃,时间80 min。ZL102 alloy was selected as the intermediate coating of a new type of packaging substrate for anodic oxidation test,and thick porous anodic oxidation film was prepared.The influence of different electrolyte,current density,temperature and time on the morphology,porosity,thickness,hardness,pressure resistance and thermal resistance of the anodic oxidation film was studied,and the experimental conditions of the thick film with the best comprehensive performance were obtained.The results show that ZL102 aluminum alloy in different electrolyte (sulfuric acid,sulfuric acid-oxalic acid,sulfuric acid-tartaric acid,sulfuric acid-citric acid),different current density (2-6 A/dm^(2)),different temperature (10-30℃)and different time (80-160 min) can form a uniform color,smooth surface oxide film.The optimum conditions of thick anodic oxide film were as follows:sulfuric acid-oxalic acid as electrolyte,current density of 6 A/dm^(2),temperature of 15℃and time of 80 min.
