Microstructure-Dependent Localized Corrosion Behavior and Formation of Corrosion-Resistant Coatings in Mg–Al–Zn Alloys: A Review
Abstract
This paper reviews recent progress in understanding the relationship between microstructure and localized corrosion behavior in Mg-Al-Zn alloys, as well as the formation of corrosion-resistant coatings.The importance of microelectrochemical techniques and in situ optical microscopy for elucidating localized corrosion processes is highlighted.Additionally, spark plasma sintering is introduced as an effective method for fabricating model specimens with α/β phase boundaries to systematically evaluate micro-galvanic corrosion.Recent advancements in pulse electrolysis for the formation of corrosion-resistant coatings on Mg alloys are also discussed.This review provides insights into localized corrosion mechanisms and offers guidance for alloy design and surface modification strategies aimed at improving the corrosion resistance of Mg-Al-Zn alloys.
