Effect of rare earth element Ce and La on corrosion behavior of AM60 magnesium alloy
TL;DR: In this article, a new AM60-RE (RE = Ce or La) alloy was prepared and its corrosion behavior was evaluated by hydrogen evolution and electrochemical methods, and the corrosion resistance of AM60 alloy improved with addition of RE, and this improvement could attribute to depression of the micro-galvanic couples.

Influence of microstructure on the corrosion of diecast AZ91D
TL;DR: In this paper, the corrosion of die cast AZ91D was studied and related to its microstructure, and it was found that the casting method can influence the corrosion performance by its influence on the alloy microstructures, which is attributed to a combination of higher volume fraction of the beta phase, a more continuous beta phase distribution around finer alpha grains, and lower porosity in the skin layer than in the interior of the die casting.
