Effects of Nanoparticles on the Properties of Chrome-Free Dacromet Coatings

Article Preview

Abstract:

Chrome-free Dacromet coating is a green anti-corrosion technology. This paper studied the effects of nanoparticles of TiO2 and SiO2 on the coatings. The results shown the addition of nano-TiO2 (T-coating )improved the physical properties and corrosion resistance. The addition of nano-SiO2 (S-coating )was week bonded with zinc and aluminium powders, resulting in the poor properties.
