.... Therefore, it is urgent to develop highly corrosion-resistant materials. In this study, the corrosion behavior of FeCoNiCrAl high entropy alloys (HEA) in molten NaNO₃-KNO₃ (60 wt% to 40 wt%) under argon at 600°C is investigated by mass loss and electrochemical methods. The results show...

... alkanolamines inhibited corrosion, and the inhibition efficiency of the three alkanolamines at a concentration of 300 ppmv was between 55% and 67% in the aqueous phase, whereas the inhibition efficiencies were low in supercritical CO₂ phase. The electrochemical experiments were used to study...

...O. Lopez-Garrity; G.S. Frankel The mechanism of inhibition of AA2024-T3 (UNS A92024) by praseodymium chloride (PrCl) at varying pH was investigated using electrochemical, microscopic, and spectroscopic techniques. Polarization curves in naturally aerated solutions showed that praseodymium (Pr...

...Faysal Fayez Eliyan; Akram Alfantazi This paper presents an electrochemical review on the corrosion behavior of iron and steel in bicarbonate and carbonate solutions. The mechanisms of dissolution and passivation are at first consolidated. The significance of microstructure and alloying composition...

... performance of materials in these facilities in biodiesel needs to be understood well to ascertain the facility integrity. The highly resistive nature of biodiesel imposes a great challenge in using the conventional electrochemical techniques for corrosion evaluation, even in the presence of water...

...F. Gui; N. Sridhar; J.A. Beavers Stress corrosion cracking (SCC) of carbon steel has been observed in fuel-grade ethanol (FGE, C₂H₅OH). Electrochemical behavior of carbon steel and therefore the role of localized corrosion in SCC has not been studied adequately because...

...F. Gui; N. Sridhar Corrosion and stress corrosion cracking of carbon steel in biofuels are a concern with the increase in the usage of ethanol as an alternate fuel. Electrochemical studies in highly resistive electrolytes (e.g., ethanol) traditionally have been conducted with the addition...

... electrochemical studies at different rotational and linear velocities have been presented. The results showed that alloys reinforced with SiC exhibited higher corrosion rates compared to unreinforced alloys. Al/SiC interface was the preferred site for localized corrosion and pitting was predominantly observed...

... (EST) was part of the Levelland, Texas municipal water distribution system. Subsequent investigations revealed that the most likely source of the perchlorate contamination was the impressed current corrosion protection system, which generated the perchlorate electrochemically in situ from...

... temperature (RT). Electrochemical techniques were used to investigate the corrosion processes. X-ray photoelectron spectroscopy (XPS) was used to characterize coating surfaces. Very low corrosion rates (≤ 2 μm/y) were measured for all coatings. It was proposed that the detrimental effect of P in EN coatings...
