Abstract

Corrosion inhibition effect of 4-cyanobenzene on 2101 duplex (2101SS) and 301 austenitic (301SS) stainless steels was studied by potentiodynamic polarization, corrosion potential measurement, optical microscopy and FTIR spectroscopy.The results showed the compound to be effective with inhibition efficiency of 98.75 % and 99.54 % for both steels.Corrosion potential of 2101SS and 301SS decreased from -0.067VAg/AgCl to -0.182VAg/AgCl, and -0.145VAg/AgCl to -0.196VAg/AgCl.Identified functional groups partially adsorbed onto both steels. The thermodynamic calculations showed physicochemicalinteraction according to Langmuir and Freundlich isotherms. The optical images showed a worn out morphology for2101SS and an etched for 301SS. The compound studied is an anodic type inhibitor on both steels.
