An alcoholic extract of a sea weed Sargassum muticum has been used to control corrosion mild steel in 0.5 N HCl. Weight loss method and Electrochemical studies have this study. study reveals that 500 ppm the inhibitor offers 99.25 % inhibition efficiency. Polarization functions as an anodic at higher concentration. The AC impedance spectra confirm formation protective film on metal surface. Ads...

The aim of this work was to revisit second-harmonic generation (SHG) as a technique for the in situ analysis oxide film formation on steel samples immersed aqueous solutions and during electrochemical experiments. measurements were compared active reflectance spectroscopy (ARS), which is more established technique. Carbon electrodes subjected polarization pH neutral mild-alkaline electrolytes p...
