Corrosion Processes of Uranus B6 and Monel 400 Special Alloys in Deep Eutectic Solvents

Abstract

The corrosion behaviour of special alloys (Uranus B6 steel and Monel 400) exposed to chlorine chloride-deep eutectic solvents (DES) at 353 K has been investigated by polarization curves method. The corresponding corrosion parameters in choline chloride-oxalic acid and choline chloride-malonic acid were calculated. Micrographic images before and after immersion in the corrosive medium were obtained. Measurements of the influence of the corrosion process on the crystal structure and specific magnetization of the studied steels was carried out by using X-ray diffraction and respectivelly ponderomotive methods.

Influence of Seawater Corrosion on Structure and Magnetic Properties of the SR355JR and S355J2 Carbon Steels

“…The polarization curves were obtained using PARSTAT 2273 with a "Power Corr" software [7] with a classical three-electrode system: platinum plate (Radiometer) as the auxiliary electrode, Ag/AgCl (0.5M KCl Radiometer) electrode as the reference electrode, and steel samples (well-deffined working surface of 1cm 2 area) as the working electrode. Natural aerated sea waters from Black, Aegean and Mediterranean seas were chosen as the electrolyte.…”
