Investigating the Impact of Varying Quantities of TiO2 Nanoparticles on the Anti-Corrosive Characteristics of TiO2-Epoxy Nanocomposite Coatings
Prepared were pills coated with TiO2-epoxy nanocomposites, and their anti-corrosive properties were studied by examining the impact of varying amounts of TiO2 nanoparticles in the epoxy resin. The anti-corrosive characteristics of pills were investigated employing electrochemical impedance spectroscopy (EIS). Based on the EIS results, the sample containing 0.01 mg of TiO2 demonstrated the highest impedance value, indicating superior corrosion resistance and better anti-corrosion properties than the other samples. Also, this sample has the lowest corrosion current density among the all samples, with a value of 1.329E-07 mA/cm2, which shows that this sample has the best corrosion resistance and a slower rate of corrosion compared to the other samples.
