The pH Dependence of Magnesium Dissolution and Hydrogen Evolution during Anodic Polarization

“…Even during extensive dissolution of Mg from anodic polarization, the characteristic potentials realized would not favor the dissolution of noble metals, which would be expected to enrich on the surface with time 14 and in such an instance could enhance the cathodic reaction rate. 15 In line with this assumption, pre-dissolved magnesium surfaces have been shown to exhibit more rapid cathodic kinetics compared to asprepared surfaces. 14,16 The notion of incongruent dissolution leading to impurity enrichment is a simple concept, however, not all the characteristics of Mg dissolution or the NDE can be explained simply by such a first order effect.…”

Corrosion properties of nickel coatings obtained from aqueous and nonaqueous electrolytes

“…Corrosion studies were carried out in three media: 0.5 M NaCl, 0.5 M H 2 SO 4 , and 2 M NaOH solutions at room temperature (≈ 20°C‐22°C). Concentrations of these media were selected based on the literature review . Potentiodynamic polarization scans and electrochemical impedance spectroscopy (EIS) tests were performed using an Autolab PGSTAT 302 N potentiostat‐galvanostat (Methrom Autolab, The Netherlands) in a three‐electrode glass cell.…”

In situ quantitative topographic measurement and corrosion behaviour of low carbon steel in chloride solutions

“…Among numerous mechanisms proposed to provide insight into the role of chloride in the corrosion process, the microstructural characteristics and structural heterogeneity, such as the grain boundaries, intrinsic composition and crystallographic orientations, play a major role in the corrosion initiation and electrochemical dissolution of low carbon steel [28]. As a result, many research efforts have been undertaken to resolve the relationship between electrochemical activities and the microstructural effects of the metals [29][30][31][32][33][34][35][36][37][38][39][40][41].…”
