New Findings

The corrosion behavior and thermal stability of epoxy coatings electrodeposited on mild steel and on mild steel with electrochemically deposited polyaniline (PANI) film were investigated by electrochemical impedance spectroscopy (EIS) and thermo gravimetric analysis (TGA). The aim of the paper was to present new findings on the corrosion protection of mild steel by a duplex PANI/-epoxy coating in 3% NaCI solution and to determine the effect of thin PANI film on the protective properties of the coating. PANI film was deposited electrochemically on mild steel from an aqueous solution of 0.5 mol dm"3 sodium benzoate and 0.1 mol dm"3 aniline at a constant current density of 1.5 mA cm"2. Non-pigmented epoxy coatings on mild steel and on mild steel with PANI film were obtained by cathodic electrode position at constant voltage and stirring conditions. The resin concentration in the electrode position bath was 10 wt.% solid dispersion in water at pH 5.7. The applied voltage was 250 V, the temperature 26?C and the deposition time 3 min. It was shown that thin PANI film could be used to modify the surface of mild steel prior to epoxy coating deposition, due to the increased corrosion protection of a duplex PANI/epoxy coating comparing to an epoxy coating on mild steel in 3% NaCl solution.

Anticorrosion Properties

This study aims at investigating the effect of inhibitor response order on anticorrosion properties of AA2024 with coating system. The inhibitor response order was constructed by adding different inhibitor in sol-gel primer or epoxy top coating of the coating system. Nanocontainers of graphene oxide/layered double hydroxides (GO/LDHs) were loaded with 2-mercaptobenzothiazole (MBT) and vanadate separately to get the inhibitors of GO/LDHs-MBT and GO/LDHs-VOx, which were used in this work. The protection performances of the coating systems with different inhibitor combination and different inhibitor response order were investigated. The best protective coating system is composed of sol-gel coating with GO/LDHs-MBT and epoxy coating with GO/LDHs-VOx. It is contributed to inhibitor combination and a proper response order of the inhibitors. When filiform corrosion occurs, MBT anions from the sol-gel coating are close to the alloy and they inhibit the corrosion in anodic areas immediately, and then vanadate anions from the out and thick epoxy coating reduce the kinetics of the cathodic oxygen reduction reaction. Response order enhances the corrosion protection properties provided by inhibitor combination, which gives a promising way to design good anticorrosive coating system.
