The failure behavior of epoxy glass flake coating in artificial seawater of various states, namely atmospheric static (0.1 MPa-0 m/s), atmospheric flowing (0.1 MPa-4 m/s), high hydrostatic pressure (10 MPa-0 m/s) and pressured-flowing (10 MPa-4 m/s) was studied by means of water absorption test, EIS, adhesion test, SEM, FT-IR, etc. The results indicated that, under the action of pressured-flowing artificial seawater, the interfacial bonding strength between pigments with the coating matrix may be significantly weakened, the structure of the coating is severely damaged, which promotes the diffusion of corrosive media in the coating, and in consequence, a large amount of water accumulates in coating defects and the interface of coating/metal, which result in significant increase in the water absorption rate and severe decrease in mechanical properties, as well as in rapid loss of coating adhesion and bubbling of the coating, as a result, the coating fails quickly. Finally, the failure mechanism of organic coatings induced by pressured-flowing artificial seawater was also discussed.
