Enhanced anticorrosion performance of zinc rich epoxy coatings
In a recently published study, the effect of a partial replacement of spherical zinc particles by stainless steel flakes (SSF) on the corrosion protection performance of zinc-rich epoxy (ZRE) coating was studied. Salt spray test, open circuit potential, electrochemical impedance spectroscopy and potentiodynamic polarisation tests were utilized to evaluate the anticorrosion performance of the coatings.
Extended the cathodic protection duration
The results demonstrate that a partial replacement of zinc particles by SSF enhanced the anticorrosion properties of the ZRE coating, and the enhancement was attributed to the synergistic effects by increasing the coating impedance and extending the cathodic protection duration.
