Abstract
The synergistic inhibition effect of CeCl3 (Ce) and serine (Ser) on the corrosion of carbon steel in a 3% NaCl solution was investigated by electrochemical methods and surface analysis. The results showed that both CeCl3 and Ser, when used alone, had limited inhibition effect toward carbon steel corrosion in the 3% NaCl solution. In contrast, the combination of CeCl3 with Ser produced a strong synergistic effect on the corrosion inhibition behavior of carbon steel, improving the inhibition efficiency significantly. The polarization curves showed that the mixture of CeCl3 and Ser acts as a cationic-type inhibitor. Scanning electron microscopy and Fourier transform infrared spectroscopy showed that the synergistic inhibition effect was due to complex formation between the cerium ions and amino acid molecules.
