Research on Effect of Organic Acids on Performance of Sulfuric Acid Anodied Film
In this paper,by adding oxalic acid,boric acid,tartaric acid and citric acid to the common sulfuric acid as the basic electrolyte,4 kinds of mixed acid oxide films are prepared successfully.Compared with traditional sulfuric acid hard oxidation process,mixed acid oxidation increases the upper limit of oxidation electrolyte temperature,saved a lot of energy and reduces the production cost.
