Application of ENA to investigate the effect of partial substitution of Zn by Al in epoxy coatings on delamination kinetics of underlying steel
Original language description
The possible effects on the protective performance of zinc-rich paints (ZRP) modified by combination of Zn dust with Al paste were investigated using electrochemical noise analysis (ENA). The role of two different Zn contents was tested for two different ZRP formulations prepared with the same vol. % Zn:Al ratio as well as with the same binder and hardener types applied. The possible losses of protective performance of both ZRP were evaluated by means of EN measurements performed for tested coatings on steel substrate specimens during 168 hrs immersion test in 0.05 mole NaCl. Due to supposed changes of cathodic nature of steel surface with immersion time ENA was used to provide information about possible delaminated corroding area time development for tested coating/steel systems.
