No full textCorrosion attack of aluminium and magnesium based alloys is a major issue worldwide. The corrosion degradation of an uncoated and atmospheric plasma sprayed alumina (APS) coatings on AZ31B magnesium alloy was investigated using immersion corrosion test in NaCl solutions of different chloride ion concentrations viz., 0.01Â M, 0.2Â M, 0.6Â M and 1Â M. The corroded surface was characterized by an optical microscope and X-ray diffraction. The results showed that the corrosion deterioration of uncoated and coated samples were significantly influenced by chloride ion concentration. The uncoated magnesium and alumina coatings were found to offer a superior corrosion resistance in lower chloride ion concentration NaCl solutions (0.01Â M and 0.2Â M NaCl). On the other hand the coatings and Mg alloy substrate were found to be highly susceptible to localized damage, and could not provide an effective corrosion protection in solutions containing higher chloride concentrations (0.6Â M and 1Â M). It was found that the corrosion resistance of the ceramic coatings and base metal gets deteriorated with the increase in the chloride concentrations

No full textThe effect of temperature and pressure on corrosion behavior of X65 carbon steel in water-saturated supercritical CO₂ containing H₂S was studied to determine the role of H₂S on the corrosion product formation and corrosion mechanism. Weight loss measurements showed that the highest corrosion rate of 0.190 mm/year was recorded at 35 °C and 8 MPa. The presence of 1000 ppmv H₂S resulted in the corrosion products comprised of a double-layer structure in both supercritical and non-supercritical conditions. The results indicated that the presence of 1000 ppmv H₂S has significantly influenced on the corrosion mechanisms, corrosion product morphology and composition as well as promoted the precipitation of water based on thermodynamic model
