Cathodic electrodeposion of nano Titania along the epoxy based coating and evaluation of its anticorrosion properties

Effect of nano TiO2 particles on the corrosion properties of an epoxy based coatings was investigated. Coatings and nano Titania were applied on standard phosphated steel panels by cathodic electrodeposition simultaneously. The coated panels were immerged in 3.5 NaCl solution for 2880 hours 120 days. The SEM and EIS technique were used to investigate the electrodeposion of nano Titania particles and corrosion properties of coatings respectively. The results showed that the nano Titania could stabilize corrosion resistance of the coatings even after a prolonged immerging in 3.5 NaCl solution.
