In-situ Mg release monitored during magnesium alloy corrosion
نویسندگان
چکیده
Quantitative in-situ and localized analytical methods that can monitor Mg release are central to probe the impact of the microstructure on magnesium alloy corrosion. As such, a potentiometric micro-Mg ion-selective membrane electrode is fabricated, calibrated, characterized and used to selectively monitor the Mg release from different cast Mg AM50 alloys during corrosion. We demonstrate that the local Mg release is tied to the alloy microstructure and its aluminum distribution, indicating a possibility of optimization of the base material corrosion properties. 2014 Elsevier B.V.
