Investigation of corrosion protection properties of SiAlON-epoxy nanocomposite coatings

In this study, the effect of adding 10wt% and 20wt% SiAlON nanoparticles in epoxy powder to improve anticorrosive properties of the nanocomposite powder coatings was investigated.Morphology of SiAlON nanoparticles and coatings were evaluated by TEM and SEM respectively. Results of Tafel and immersion test indicate that SiAlON nanoparticles have important role in improving the protective properties. Also Penetration of the electrolyte through the coatings is decreased significantly in coating with 10wt% SiAlON
