Abstract Scope |
Corrosion behavior of Mg alloy is one of key factors to determine the applicability of Mg alloys to automotive and other electronic components. However, the corrosion measurement for Mg alloys is time-consuming and highly dependent on the sample preparations and other experimental environmental factors. In order to build up the corrosion map data for various Mg alloys depending on the alloy composition and microstructure, more efficient novel corrosion measurement technique is required. In this study, we would like to present new efficient corrosion measurement technique coupling scanning electrochemical microscopy (SECM) and diffusion couple of Mg alloys. Using 250-nm diameter micropipette tip in contact with the surface of Mg sample, SECM can allow to measure the variation of corrosion potential of Mg alloy across the diffusion couple in a single scan. As an example of new novel method, the corrosion potential data of the Mg/Al diffusion couple will be demonstrated. |
