Research on AC deposition behavior on LY12 aluminum alloy composite oxide film in zinc sulfate solution
摘要
Abstract
By using alternating current （AC） deposition, the reaction compound oxide layer is investigated through tracking the current change Zn on the surface of LY12 aluminum alloy＇s sulfate - phosphate composite by using oscilloscopes. The experimental results indicate that zinc mainly process of zinc ion in the in the process of depositing oxide film （composite film） distributes at the bottom of composite film holes and is about 2 μm to the bottom when LY12 aluminum alloy composite oxide film is deposited in zinc sulfate solution for 300 s. The sediment yield is 31. 404 μg/cm^2. At the initiative period of switching on power supply, the anodic and the cathodic peak currents through the oxide film change very rapidly, and the latterrs value is greater than the formert s. After that, they become equal. At the same time, the composite film＇s color changes, which indicates Zn is deposited into the composite film hole. The sediment yield of zinc on the composite film and time of sediment have a logarithmic relationship.关键词
