| Abstract Scope |
Mg alloys are considered one of the most attractive structural materials for mobile goods such as personal vehicles and portable devices. However, industrially using Mg-based products in a variety of weight-sensitive components is still limited especially due to their poor corrosion resistance. It has been reported that the poor corrosion resistance is closely related with the occurrence of active microgalvanic corrosion between the Mg matrix and second-phase particles.
Here, we report highly corrosion-resistant AZ-based Mg alloys whose corrosion resistance is equivalent to that of ultra-high-purity Mg, which is nearly free of the occurrence of microgalvanic corrosion in corrosive conditions. The excellent corrosion resistance appearing in the experimental Mg alloys is attributable to the reduced nobility of cathodic second-phase particles after controlled microalloying with rare-earth elements, resulting in significantly retarded microgalvanic corrosion in NaCl solution. Designing concept of the new Mg alloys and their industrial implementation trials will also be presented. |
