摘要: Abstract The chemical nature of the coordination compound film formed by reacting PMTA (1-phenyl-5-mercaptotetrazole) with a copper surface has been studied accelerated corrosion tests, linear sweep voltammetry (LSV), cyclic (CV), Fourier-transform infrared spectroscopy (FT-IR), X-ray photoelectron (XPS) and Auger electron (AES). These studies show that, in retarding substrate, is superior to those TTA (tetrazole), BTA (benzotriazole), HBTA (hydroxybenzotriazole), MBT (2-mercaptobenzothiazole), MBI (2-mercaptobenzo-imidazole), 2-AP (2-aminopyrimidine), IBM (imidazole) chromates. characterized found be polymeric complex Cu–PMTA. mechanism for formation relationships between this novel structure observed inhibition behavior are discussed.
