Superior synergistic corrosion inhibition of brass in NaCl solution by 2-mercaptobenzothiazole and TiO2 nanoparticles compared with SiO2 (opens in new tab)

2-Mercaptobenzothiazole (MBT) combined with nanoparticles exhibits a synergistic corrosion inhibition effect for brass in 3.5% NaCl solution. The corrosion behavior was evaluated using open circuit potential (OCP), electrochemical impedance spectroscopy (EIS), and potentiodynamic polarization techniques. The inhibition efficiency increased with MBT concentration (0–20 ppm), reaching 97.4% at 20 ppm. The addition of 10 ppm nanoparticles further enhanced the inhibition performance. In particula...
