Eco-friendly chalcones derivatives as corrosion inhibitors for carbon steel in hydrochloric acid solution

  The inhibiting effect of some chalcones derivatives on the corrosion of carbon steel in 1 M HCl was studied by weight loss, potentiodynamic polarization, electrochemical impedance spectroscopy (EIS) and electrochemical frequency modulation (EFM) techniques. The results showed that the inhibition efficiency increases with increasing the inhibitor concentration, while it decreases with increasing the...

Aqueous extract of propolis as corrosion inhibitor for carbon steel in aqueous solutions

  The inhibition efficiency of aqueous extract of propolis on the corrosion of carbon steel in 35 ppm aluminum sulfate and 10 ppm chloride solution was investigated by weight loss and electrochemical measurements. The corrosion rate of carbon steel and the inhibition efficiency of the propolis were calculated. The results obtained showed that propolis could serve as an effective inhibitor for the corrosion of...
