TL;DR: In this paper, the effect of Chamomile (Chamaemelum mixtum L.), Halfabar (Cymbopogon proximus), Black cumin (Nigella sativa L.), and Kidney bean (Phaseolus vulgaris L.) plants on the corrosion of steel in aqueous 1-M sulphuric acid were investigated by electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization techniques.

TL;DR: In this paper, the effect of lupine extract on the corrosion of steel in aqueous solution of 1M sulphuric and 2M hydrochloric acids was investigated by potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) techniques.

TL;DR: In this article, the dissolution of aluminium in 1-M sulphuric acid solutions containing different chloride ion concentrations (0.01-0.06) were studied at 25, 30, 35 and 40°C using electrochemical impedance spectroscopy (EIS) technique and polarization curves measurements.

TL;DR: In this paper, the inhibitive effect of damsissa (Ambrosia maritime, L.) plant extracts on the corrosion of steel in an aqueous solution of 1 M sulfuric acid (H2SO4) was investigated in the temperature range from 25°C to 40°C using potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) techniques.

TL;DR: The effect of addition of chloride ion on the corrosion of stainless steel 304 in Na2SO4 solution under constant ionic strength conditions at 30°C was studied using potential-time and potentiodynamic polarization techniques and it was found that the added chloride ion reduces the growth of protective passive film on the surface and increase corrosion current.
