In this work the nanotubes and nanosheets (layers) structures of nanocarbon materials were used for the investigation. The properties of received products were measured by the test techniques for paint coating characterization. The results showed that the addition of the nanocarbon materials (only ratio of wt%) significantly improved the physico-mechanical performance and corrosion protection ability of epoxy coatings for steel surfaces. However improvement quantity depends on the structure of nanocarbon materials. The obtained results showed that the nanosheets structure of carbons coatings made the physico-mechanical properties of the epoxy coating increased better than those of nanotube structure. Keywords: nanocarbon epoxy paint coatings. materials, graphene, carbon nanotubes, corrosion protection property, 1. INTRODUCTION Metals are selected as construction material because of their mechanical properties and machine-ability at a low price but they are not resistant in the corrosion medium. The coatings of anti-corrosion paint always play essential role in this area. By applying an appropriate coating, a base metal with good mechanical properties can be utilized. Many alloys have been developed to resist corrosion. However, the use of these materials may not be practical from the standpoint of cost, based on the specific application. In addition, a .
