摘要：

Electrochemical polarization and electrochemical impedance spectroscopy (EIS) were involved to study the corrosion inhibition of aluminum alloy 2024 in 2.5M H2SO4 solution by 4-amino-5-pheny1-4H-1, 2, 4-triazole-3-thiol (APTT) at 30 degrees C. Potentiodynamic polarization results were comparable with those obtained by impedance measurements. Results showed that APTT performed as inhibitor for aluminum alloy 2024 corrosion in 2.5M H2SO4 solution and it attains an efficiency of more than 32% at 4x10(-4) M at 30 degrees C. The inhibition efficiency increases with an increase in the concentration of APTT. Polarization curves show that APTT is a mix-type inhibitor. Changes in impedance parameters (charge transfer resistance, R-ct, and double layer capacitance, C-dl) were indicative of adsorption of APTT on the aluminum alloy 2024 surface, leading to the formation of protective films
