Abstract
The inhibitive action of 3-amino-1,2,4-triazole (ATA) on 70Cu-30Zn alloy corrosion in HNO3 0,5M was examined. Gravimetric and electrochemical tests were used. The results obtained show that the ATA reduces effectively the dissolution of 70Cu-30Zn alloy. The inhibition efficiency in aerated acid increased with increasing ATA concentration to a maximum of 69% at 10-2M. The adsorption of the inhibitor is found to obey to the Langumir adsorption isotherm.
