Cerium tartrate as pigment in epoxy coatings for corrosion protection
The results of release measurements of Ce ions from epoxy coating in 0.05 mol/L NaCl indicate that cerium ions are able to transport through the epoxy coating, which is a key characteristic of inhibitor pigment.
Improving the barrier effect
The electrochemical impedance spectroscopy (EIS) shows that cerium tartrate is an effective pigment for improving the barrier effect of epoxy coatings on AA2024-T3. The self-healing ability of cerium tartrate in artificial defects was verified by scanning vibrating electrode technique (SVET).
