Abstrak

The synergistic corrosion inhibition effect of phytic acid (PA) and benzyltrimethyl ammonium bromide (BAB) on 1045 carbon steel (CS) in 0.5 M HCl is reported. Electrochemical measurements showed that PA and BAB can reduce the corrosion rate of 1045 CS in HCl solution and act as excellent corrosion inhibitors. The best inhibition efficiency ni of the combination inhibitor of PA with BAB is 90.6%. SEM images of the corroded steel surfaces suggest that the PA and BAB are simultaneously adsorbed on the CS surface to inhibit the corrosion of iron. The synergistic inhibition mechanism is investigated by dynamic simulations and quantum chemistry.
