Item Electrochemical investigation of ceria nanoparticles as a corrosion inhibitor for steel in alkaline medium(2023) Bourenane, N; Hamlaoui, Y; Pedraza, FThis work investigates the synthesis and the corrosion inhibitor efficiency ceria nanoparticles may exert on steel reinforcement in an alkaline solution of saturated Ca(OH)2 + 0.5 M CaCl2 up to 50°C. The corrosion mechanisms are thoroughly investigated by electrochemical and various characterization techniques. The electrochemical results show that ceria nanoparticles act as an anodic inhibitor and provide maximum inhibition efficiency (80%) at a concentration of 800 ppm. The resulting surface is smooth and free from corrosion products due to the formation of a physically adsorbed film according to the thermodynamic calculations.
