摘要：

Clear epoxy coatings were modified by adding various levels of ZrO2 nanoparticles In order to achieve proper dispersion of nanoparticles in the epoxy-based coating and making possible chemical interactions between nanoparticles and polymeric coating the surface of the nanoparticles was treated with amino propyl trimethoxy silane (APS) Corrosion performance of mild steel coated specimens was investigated employing EIS electrochemical noise (ECN) techniques and salt spray test Coatings with 2-3 wt% ZrO2 nanoparticles possessed the best corrosion performance among the coating specimens Possible chemical interactions between polymeric matrix and treated nanoparticles in nanocomposites cause high barrier properties and ionic resistances (C) 2010 Elsevier Ltd All rights reserved
