Numerical Investigation of Micro-Galvanic Corrosion in Mg Alloys: Role of the Cathodic Intermetallic Phase Size and Spatial Distributions

2020
Magnesium alloys are of increasing interest in structural applications due to their low-density, moderate specific strength and stiffness, recyclability, and high damping among other properties. However, the wide-scale applicability of magnesium alloys in structural applications has been limited due to many factors including its poor corrosion ...

Effect of anodic T phase on surface micro-galvanic corrosion of biodegradable Mg-Zn-Zr-Nd alloys

Applied Surface Science, 2018
Abstract A complete understanding of the role of Mg-Zn-Nd (T) phase in surface micro-galvanic corrosion of Mg alloys has not been fully developed. Therefore, the microstructure evolution and corrosion behavior in simulated body fluid (SBF) of Mg-2Zn-0.6Zr-xNd alloys (x = 0, 0.2, 0.6 and 1 wt%) were investigated. It was found that the MgZn phase in Mg-

First-principles study of work functions and micro-galvanic corrosion between Mg and Mg–Dy intermetallics

Modelling and Simulation in Materials Science and Engineering
Abstract The rare earth element Dy, as an alloying element, is applied in the preparation of binary magnesium alloys and has a positive impact on the corrosion resistance and mechanical properties of magnesium alloys. However, during the solidification process of Mg–Dy alloys, second phases with different electrochemical potentials from ...
