Influence of oxalic additive on etidronic acid anodizing of aluminum alloy
The anodizing in etidronic acid (HEDP) and oxalic acid (H2C2O4) mixed electrolytes was conducted. The anodizing parameters were optimized based on the evaluation of energy consumption, growth efficiency, and hardness of PAA film. The results indicate that continuous and uniform PAA films can be fabricated in HEDP/H2C2O4 solutions in any proportion, and both the anodizing voltages and roughnesses of PAA films decreased with the H2C2O4 content. The moderate amount of H2C2O4 could lead to an increase in the formation efficiency of PAA films. The hardness of the PAA film prepared in HEDP/H2C2O4 electrolyte could reach up to ∼660 HV. Moreover, a surface resembling lotus leaves could be formed due to the corrosion of PAA films with sub-micron interpore distance by H2C2O4 during anodizing, and a superhydrophobic surface with a contact angle of ∼153° could be obtained after it was modified via stearic acid.
期刊介绍：
The Journal of Electroanalytical Chemistry is the foremost international journal devoted to the interdisciplinary subject of electrochemistry in all its aspects, theoretical as well as applied.
Electrochemistry is a wide ranging area that is in a state of continuous evolution. Rather than compiling a long list of topics covered by the Journal, the editors would like to draw particular attention to the key issues of novelty, topicality and quality. Papers should present new and interesting electrochemical science in a way that is accessible to the reader. The presentation and discussion should be at a level that is consistent with the international status of the Journal. Reports describing the application of well-established techniques to problems that are essentially technical will not be accepted. Similarly, papers that report observations but fail to provide adequate interpretation will be rejected by the Editors. Papers dealing with technical electrochemistry should be submitted to other specialist journals unless the authors can show that their work provides substantially new insights into electrochemical processes.
