TLDR
In this paper, a combined experimental and thermodynamic analysis suggests that the ability of magnesium to support the cathodic reaction is enhanced during dissolution as the result of an increase in the exchange current density for the hydrogen evolution reaction, which can also explain high rates of hydrogen evolution in aluminium pits.About:

Combining peridynamic and finite element simulations to capture the corrosion of degradable bone implants and to predict their residual strength

TL;DR: In this paper , a peridynamic (PD) corrosion model is used to tackle the complex moving boundary of the corroding material in an efficient manner, and the results of this corrosion simulation are mapped to a finite element (FE) model by way of a damage variable.

The Initial Stages of Electrodeposition of Re-Ni Alloys
TL;DR: In this paper, the early stages of Re-Ni alloy deposition from citrate electrolytes were studied in terms of the apparent faradaic efficiency (FE) of the deposition process, the composition of the deposits and their morphology.
Passivation and Potential Fluctuation of Mg-Alloy AZ31B in Alkaline Environments
TL;DR: In this paper, the passivation and corrosion behaviors of Mg alloy AZ31B were investigated in chloride-free NaOH solutions with pH range from 10 to 14, and the results indicate that various phases behave differently at different pH levels.
Journal ArticleDOI
Anodic hydrogen evolution on Mg
TL;DR: In this paper, the authors measured the anodic hydrogen evolution rates for various applied anodic current densities and estimated the corresponding cathodic hydrogen degradation rates, contradicting the enhanced catalytic activity mechanism of Mg corrosion.

The anodic dissolution of magnesium in chloride and sulphate solutions
TL;DR: In this article, the electrochemical behavior of magnesium was studied in representative chloride and sulphate solutions including NaCl, Na2SO4, NaOH and their mixed solutions, HCl, and H2SO 4: (1) by measuring electrochemical polarisation curves, (2) by using electrochemical impedance spectroscopy (EIS), and (3) by simultaneous measurement of hydrogen gas evolution and measurement of magnesium dissolution rates using ICPEAS.
