... promoted SSC, suggesting that SSC was affected by both active path corrosion (APC) and hydrogen embrittlement (HE) mechanisms. In addition, the fissure shapes and crystal orientations of the microstructure were analyzed to classify the fissures as dissolution (corrosion) or mechanical cracking. Further...

... speciation in acidic systems is demonstrated. The electrochemical module, which incorporates partial anodic and cathodic reactions, can model active corrosion, active-passive transition, as well as dissolution in the passive state. The model is shown to quantitatively predict the corrosion rates of two...

... by the dissolution of H2S gas into the brines which is typically accompanied by an increase in the hydrogen proton concentration. However, the further significant drop in pH noticed in brines containing cations (Pb2+ and Zn2+) show that this drop is due to the combination of dissolution of H2S gas and precipitation...

..., recycling processes involve one or several steps such as conversion, depolymerization, dissolution, mechanical treatment, etc Highly corrosive environments can be found, including high temperature and aggressive fluids. Some of the elementary steps of plastics recycling resemble proven processes...

... processing as a semi-quantitative technique, it became feasible to generate transient 2D maps with proper detail regarding the pH evolution into the electrolyte and to provide new information about the galvanic corrosion of Mg. Findings revealed a significant pH decrease in regions where Mg dissolution...

... dissolution rate. This behavior is attributed to the formation of NiCO 3 and NiS. The H 2 S content within the supercritical CO 2 phase can support a high cathodic reaction rate through the S reduction reaction, which is incorporated in the passive layer to form Ni sulfides, this creates a passive layer...

... the corrosion of galvanized armor wires in the aqueous fluid system (AFS) using weight-loss analysis and electrochemical techniques. A novel corrosion test protocol was developed to accurately measure both zinc dissolution and surface oxidation of the zinc coating. The degradation of the zinc coating...

... and corrosion behavior of galvanized steel treated with Ce in 0.3 wt.% NaCl. The authors observed formation of Ce oxide and/or hydroxide on galvanized steel which constrained the cathodic reduction of oxygen and the anodic dissolution of zinc, leading to a decrease of the corrosion rate [11]. Many studies have...

Responsibility for the content of the work lies solely with the author(s). 3 passive film forms on the corroding metal surface at the bottom of the pit and repassivates the surface. This passive film reduces the kinetics of metal dissolution and lowers...

... ABSTRACT In this work, a new approach is introduced to determine the kinetic constants of the elementary steps involved in the overall reaction of iron anodic dissolution. A procedure based on transient analysis is established, for the first time, that enables the estimation of a series...
