| titleOfInvention | A Dense Oxidation Process of Aluminum Alloy Surface under Constant Ion Gradient |
| abstract | The invention relates to the surface processing of aluminum alloy devices, and belongs to the field of metal material surface treatment. The aluminum alloy surface dense oxidation process under constant ion gradient, the aluminum alloy device is placed in an anodizing solution, and the oxidation voltage pulse and ultrasonic vibration pulse are alternately applied for anodization; the ultrasonic vibration pulse is transferred from the solution vibration to the vibration of the aluminum alloy body. , Through the rigid aluminum alloy itself, the ultrasonic wave is transmitted to the solution everywhere on the surface of the alloy, avoiding the difference in the distribution of ultrasonic pulse density in the previous solution, and it is difficult to effectively eliminate the problem of unbalanced oxidation caused by the change of ion concentration difference. The technical solution can form a dense aluminum oxide film with a uniform and stable thickness and a consistent crystal form on the surface of the aluminum alloy device, which can resist the corrosion of an extreme acid-base environment. |
