Summary: The pitting corrosion susceptibility of 904L stainless steel in aerated LiBr solutions was studied using electrochemical measurements. The experimental variables, including electrolyte concentrations, pH, scan rate, temperature, and constant potential, were investigated. The results showed that the uniform corrosion rate and pitting corrosion susceptibility increased with increasing LiBr concentrations and temperature. Increasing the pH of the solution decreased both corrosion rates. An increase in scan rate enhanced uniform corrosion but suppressed pitting corrosion. EIS diagrams displayed a depressed semicircles with the center under the real axis. Bode plots supported the result that the uniform corrosion resistance decreased with increasing Br- anion concentration in LiBr solutions. The observations suggested that the observed single time constant may actually be the overlap of two time constants.

Summary: Alloys 600 and 800 showed stable pitting corrosion, while Alloy 690 exhibited only metastable pitting, in 1 M NaCl plus thiosulfate deaerated solutions at the open circuit potential and room temperature. Stable pits nucleated near Ti-rich inclusions and increased in diameter after a certain period of time. Prepassivation treatment can inhibit this mechanism of pitting corrosion.

Summary: The corrosion behavior and corrosion rate of friction stir welded AZ31B magnesium alloy and 6N01 aluminum alloy dissimilar joints were studied using real-time imaging, potentiodynamic polarization, EIS, and hydrogen evolution tests. The corrosion rate was found to increase in the order of Al base metal < Mg base metal < stirred zone. The galvanic coupling of the Mg phase to other phases enhanced the corrosion of both base metals, and intense corrosion at BM-AZ31B elevated the interfacial pH due to water reduction on the cathodic particles of BM-6N01.

Summary: This study investigates the influence of biologically relevant ions on the corrosion of zinc in physiological fluids. Electro-chemical techniques were used to study the degradation of pure zinc exposed to different physiological electrolytes containing chlorides, carbonates, sulfates, and phosphates. The most aggressive ions are chlorides, while carbonates and phosphates reduce the corrosive attack and sulfates disrupt the passive layer of zinc, altering its corrosion behavior.

Summary: The study investigated the effect of Henna extract as an inhibitor on the corrosion behavior of API 5L Gr.B steel in H2S-containing solution at 25 degrees C. Results showed that the corrosion current density decreased and inhibition efficiency increased with higher Henna extract concentration. Quantum chemical calculations revealed Lawsone as the main constituent and inhibition agent in Henna extract.

Summary: Thermal treatment induces changes in phase composition and microstructural parameters of the alloy, which in turn affect its corrosion behavior in different solutions. In addition to phase composition, crystal orientation and the state of the alloy surface also play a significant role in overall corrosion behavior.

Summary: The effect of Ti content on the microhardness and crystallization structure of aluminum-titanium alloys was studied. The corrosion rate of the alloys was higher than that of pure aluminum, and increased with an increase in Ti content and temperature. The changes in the entropy, enthalpy, and apparent activation energy of the corrosion processes were evaluated. The corrosion current density in H3PO4 was lower than that in HCl.

Summary: This study focused on obtaining a black coating on a low carbon steel surface using three different solutions, revealing that the protective layer obtained through 15 minutes immersion at boiling point was dense and adherent, while longer or shorter immersion times resulted in non-uniform layers with porosities. The use of a cold solution led to an uneven layer and reduced corrosion resistance. The morphology, color, defects, composition, and corrosion resistance of the protective layer were evaluated through various microscopic and spectroscopic techniques.

Summary: The study evaluated the corrosion behavior of the multilayered Cr/GLC coating in artificial seawater under different pressure conditions, showing that the corrosion resistance was better at 1 atm but deteriorated significantly at 300 atm. The results suggest the importance of fabricating dense coatings for deep-sea applications.

Summary: In this study, the corrosion inhibition effect of Allium Jesdianum extract (AJE) on mild steel in 1 M HCl solution was evaluated through various corrosion tests. The maximum inhibition efficiency reached approximately 96.18%, with inhibition performance depending on AJE concentration. The adsorption of the extract on the metal surface followed the Langmuir adsorption isotherm, and surface morphology and characterization methods were used to verify the inhibition mechanism.

Summary: The study found that the critical point where the corrosion rate changes is at 12% strain level, before which the corrosion rate first increases and then decreases. The antagonistic effect of basal structure and dislocation aggregation plays a crucial role in corrosion resistance. With an increase in strain, the number of twins increases, causing a continuous decrease in corrosion resistance.

Summary: This study reports on berberine isolated from Mahonia nepalensis as a highly efficient and thermally stable corrosion inhibitor for mild steel in acid pickling condition. Berberine showed fast adsorption and achieved high inhibition efficiency in a short time, with even higher efficiency at higher concentrations and temperatures. The results support both physical and chemical interactions of berberine with the steel surface, showing endothermic and spontaneous adsorption process.
