The corrosion inhibition properties of the benzothiazole BTH and benzotriazole BT inhibitors on the aluminum in 0.25 M HCl solution were studied. Electrochemical impedance spectroscopy EIS, electrochemical noise EN and potentiodynamic polarization techniques were used to investigate the inhibition properties of the inhibitors. Scanning electron microscope SEM was also utilized in order to inves...

In this work, polypyrrole/ZnO nanocomposite (PPy/ZnO NC) was produced through synthesis of polypyrrole polymer in the presence of ZnO nanoparticles. The corrosion behavior of polyvinyl butyral coatings without and with different weight percentages of nanocomposite on the surface of 7075 Al alloy was investigated in 3.5% NaCl solution at different immersion times using electrochemical impedance ...
