Pitting corrosion of carbon steel in sodium chloride solution induced by Ce[Formula: see text] and the synergistic inhibition effects of Ce[Formula: see text] and Zn[Formula: see text]/SiO[Formula: see text] were investigated using in-situ observation and electrochemical methods. The results showed that the presence of Ce[Formula: see text] could result in severe pitting corrosion and a positive shift in the corrosion potential. It was found that individual Ce[Formula: see text], Zn[Formula: see text], or SiO[Formula: see text] had low inhibition efficiencies, whereas the combination of Ce[Formula: see text] and Zn[Formula: see text] or SiO[Formula: see text] proved to be highly effective in inhibiting the development of pits in two different ways and in enhancing the corrosion resistance. The pitting corrosion and inhibition mechanisms were discussed based on the results.

Addition of less than 0.32 mM phosphate (10 mg/L as P) to synthetic potable waters delayed pit stabilization in copper by raising the pitting potential. Phosphate additions to synthetic drinking waters also repassivated propagating artificial copper pits but only at high phosphate concentrations such as 1.6 mM or 3.2 mM (50 mg/L or 100 mg/L as P). The inhibition efficacy of phosphate was a function of both phosphate concentration and preexisting artificial pit depth. Pit growth was easier to suppress when artificial pits were shallow (e.g., ~20 μm) compared to deep pits (e.g., ~250 μm). The inhibition effect of phosphate on copper pitting corrosion was reversible. Upon removal of phosphate from the bulk solution, pits grew at increasing rates. Two inhibition mechanisms capable of explaining the effect of phosphate on copper pitting are discussed.
