摘要:
研究了微弧氧化主盐溶液中十二烷基苯磺酸钠和十二烷基硫酸钠浓度对电子元器件用LY12铝合金表面微弧氧化膜层厚度、膜层表面和截面形貌、物相组成和电化学性能的影响。结果表明，随着电解液中十二烷基苯磺酸钠浓度的提高，膜层厚度呈现先增加而后减小的趋势，当其浓度为0.04 g/L时膜层厚度达最大。溶液中添加不同浓度十二烷基苯磺酸钠或十二烷基硫酸钠后得到的微弧氧化膜层的腐蚀电位均高于基础主盐膜层，相应的耐腐蚀性能更好。微弧氧化膜层的厚度与耐腐蚀性能之间没有明显的对应关系，而与膜层中显微孔洞数量及其分布有关。
Abstract:
The effects of concentration of sodium dodecyl benzene sulfonate and sodium dodecyl sulfate on the thickness, surface and cross-section morphology, physical and electrochemical properties of surface micro arc oxidation film on LY12 aluminum alloy were studied. The results showed that the thickness of the film increased first and then decreased with the increase of the concentration of sodium dodecyl benzene sulfonate, which reached the maximum when the concentration was 0.04 g/L. The corrosion potential of the oxidation film shifted positively compared with basic salt coating after adding sodium dodecyl benzene sulfonate and sodium dodecyl sulfate into the solution, which implied the better corrosion resistance. There was no obvious relationship between the thickness of micro arc oxidation film and the corrosion resistance, but it is related to the number and distribution of micro pores in the film.
