Abstract Epoxy nanocomposite coatings are an essential way to protect petroleum storage tanks from corrosion.For this purpose, the new nanocomposite epoxy coatings (P-M/epoxy composites) have been successfully designed.The P-M/epoxy composites are based on the metal vanadium oxy-phosphate M0.

5VOPO4 (where M = Mg, Ni, and Zn).The function of P-M/epoxy composites Buffered C as anti-corrosion coatings was explored using electrochemical and mechanical tests.Using electrochemical impedance spectroscopy (EIS), it has been noticed that the pore resistance and polarization resistance of the P-M/epoxy composites remain higher as compared to the neat epoxy.

The P-M/epoxy composites have the greatest impact on the cathodic dis-bonded area and water absorption.Besides, P-M/epoxy composites exhibit a very high order of mechanical properties.Further, Mg0.

5VOPO4 has the greatest effect on the anti-corrosion EAR WAX RELIEF properties of epoxy coating followed by Zn0.5VOPO4 and Ni0.5VOPO4.

All these properties lead to developing effective anti-corrosion coatings.Thus, the net result from this research work is highly promising and provides a potential for future works on the anti-corrosion coating.
