采用常规阳极氧化法 ,研究电解液中各成分和电解规范对复合阳极氧化膜层性能的影响后 ,提出了添加 Si C粉体硫酸溶液中铝的复合阳极氧化工艺。实验结果表明 :该工艺具有操作容易、设备简单、成本低等特点 ,与常规阳极氧化比较 ,其氧化速度、操作温度上限和膜层性能均有显著提高 The conventional anodizing method was used to study the influence of the composition of the electrolyte and the electrolytic standard on the performance of the composite anodic oxide film. A composite anodic oxidation process of adding aluminum in Si C powder sulfuric acid solution was proposed. The experimental results show that the process has the advantages of easy operation, simple equipment and low cost. Compared with the conventional anodization, the oxidation rate, the upper limit of the operating temperature and the film performance are significantly increased
