Synergistic Corrosion Inhibition of AA2024-T3 by Sodium Silicate and Sodium Molybdate

摘要

The effect of mixing sodium silicate and sodium molybdate on the corrosion inhibition of AA2024-T3 was investigated using various electrochemical, microscopic and spectroscopic techniques. Strong synergistic behavior was observed when silicate and molybdate were mixed together in solution resulting in much lower threshold concentrations for corrosion inhibition.
