摘要: The corrosion inhibition behavior of benzotriazole (BTA) on copper in 17 wt% tetra-n-butylammonium bromide (TBAB) aerated aqueous solution was investigated by weight-loss tests, potentiodynamic polarization, electrochemical impedance spectroscopy, and scanning electron microscopy/energy dispersive X-ray spectroscopy. BTA is a good inhibitor TBAB solution. efficiency increases with increasing concentration, attaining efficiencies up to 90% calculated according different methodologies. Adsorption the surface found obey Langmuir adsorption isotherm.
