Özet

© 2020 Author(s).The inhibition effect of a triazolopyrimidine derivative, i.e., 6-hydroxy-5-phenyl-5,6-dihydro-[1,2,4]tria zolo[4,3-a]pyrimidin-7(8H)-one (HPDTP), against the corrosion of mild steel in 1 M HCl solution was investigated by electrochemical test. We find that the inhibition efficiency increases with inhibitor concentration and it attains an efficiency of more than 90% at 10-3 M. Polarization curves show that HPDTP is a mix-type inhibitor. Changes in impedance parameters were indicative of adsorption of HPDTP on the steel surface, leading to the formation of a protective film. Our findings will contribute to the development and application of novel corrosion inhibitors.
