Evaluation of AC corrosion under anodic polarization using microzone pH analysis
Source abstract
Abstract
A method called the response surface methodology was designed to explore the corrosion characteristics under the combined action of an alternating current (AC) and a direct current (DC). High AC levels were found to inhibit anodic DC corrosion. The microzone pH increased significantly compared with that of the bulk solution when the anodic DC was coupled with a high AC. Ion migration at the interface under the interference was analyzed to evaluate the pH changes. By combining the effects of the pH variations with the Pourbaix diagram, a reasonable mechanism is proposed for the AC+DC mixed interference corrosion process.
