... polarization, electrochemical impedance spectroscopy and chronoamperometry. Scanning electron microscopy and X-ray diffraction were used to investigate the morphological characteristics and main phase compositions of corrosion products. Moreover, the atmospheric corrosion mechanism of aluminum under current...

... these alloys. As the carried current increased, the corrosion rate and corrosion current density of the aluminum alloys gradually increased, with the protection of the corrosion product film decreasing linearly. Originality/value This is a recent study on the corrosion behavior of conductors under current...

... partial pressure of 1 atm by recording open circuit potential/time and potentiodynamic polarization characteristics. The surface and cross-sectional morphologies of corrosion product scales were characterized using scanning electron microscopy. The phases of corrosion product scales were investigated...

... string. In this work, the methods of static weight loss, potentiodynamic polarization curves, electrochemical impedance spectroscopy (EIS), surface morphology analysis and corrosion product analysis were used to study the corrosion behavior of N80 steel (an important steel in oil drilling) in 5 per cent...

... techniques. Findings – The results show that as tensile stress was increased, the open-circuit potential decreased, the reaction activity increase, the reaction resistance (Rct)value became smaller by degrees, the corrosion product film resistance (Rf) first decreased and then increased...

... in CO₂/H₂S oil field-produced water. Design/methodology/approach – The corrosion products formed on the steel surface were observed and analyzed using scanning electron microscope (SEM) and X-ray diffraction (XRD). Findings – The results indicate that temperature significantly...

... cast iron, with slag inclusions of FeS strips and phosphate. Porous or hexagonal platey corrosion products were discovered on the archaeological iron coin, which were mainly identified as Fe₂O₃, FeOOH, Fe_x(OH)_1−xCO₃...

... different withdrawal velocities were subjected to total immersion tests in distilled water and in 3.5 per cent NaCl solution and to DC polarisation tests in distilled water. XPS analyses conducted on samples after polarisation indicated the presence of an La compound in the non passive corrosion products...
