Abstract
The corrosion inhibition properties of the benzothiazole and benzotriazole inhibitors on the aluminum in 0.25 M HCl solution were studied. Electrochemical impedance spectroscopy, electrochemical noise and potentiodynamic polarization techniques were used to investigate inhibition properties of the inhibitors. Scanning electron microscope was also utilized in order to investigate the surface morphology of the samples. Results showed that benzotriazole and benzothiazole significantly reduced the corrosion rate of the aluminum. A higher corrosion inhibition efficiency of the benzotriazole compared with benzothiazole was obtained. It was shown that electrohemical noise is an appropriate technique for studying the corrosion inhibition properties of the corrosion inhibitors.
