Effect of Deep Eutectic Solvent Composition on the Corrosion Behavior of Electrodeposited Cadmium Coatings on Carbon Steel

Abstract

Deep eutectic solvents prepared by mixing choline chloride with urea or thiourea (1:2 molar ratio) were employed to evaluate their effects on the formation of cadmium electrodeposits on a reactive electrode composed of carbon steel 1018. The corrosion protection of carbon steel corresponds to the use of cadmium as a sacrificial anode. Differences in DES affect the electrochemical and corrosion behavior of cadmium.
