Electrochemical studies on Zn/nano-CeO2 electrodeposited composite coatings

► Carbon steel is surface engineered by Zn-CeO2 composite coating. ► Effect of CTAB on CeO2 incorporation and corrosion is studied. ► Effect of CeO2 on HERs and Zn electrodeposition is evaluated with and without CTAB. ► Corrosion resistance of Zn-CeO2 is very high compared to bare zinc. ► Overall electrochemical survey on deposition and process of corrosion in 3.5 wt.% NaCl
