additive. In this study, we prepared two epoxy coatings without and with zinc phosphate for corrosion protection of AA7075-
T6 substrates for different time exposures in NaCl solution. The two epoxy coatings were evaluated by electrochemical
impedance spectroscopy and their surfaces were characterized by scanning electron microscopy. The results show that the
addition of zinc phosphate to the anticorrosive formulation (epoxy resin–polyaminoamide) facilitated the formation of a
barrier film, enhanced the barrier anticorrosive properties of the coatings and therefore inhibited the penetration of aggressive
corrosive ions to the AA7075-T6 surface.
