Abstract

Abstract : The inhibition of AA2024-T3 corrosion by the synergistic combination of 3-Amino-1, 2, 4-triazole-5-thiol (ATAT) and cerium chloride in sodium chloride solution is assessed. Analysis of electrochemical impedance spectroscopy results show improved corrosion inhibition for the inhibitor combination by increased charge transfer resistance. Scanning vibrating electrode technique was utilized for corrosion current monitoring and quantification. X-ray photoelectron spectroscopy and time of flight secondary ion mass spectrometry were utilized to characterize the ATAT/Ce based film and to explain the mechanism of inhibition. The obtained results demonstrate a good potential of the inhibitor combination for improved suppression of corrosion processes.
