摘要

The corrosion of inhibition of mild steel has been monitored by Ethane-2-thioamido-4-amino-N-(5-methylisoxazol-3-yl)-benzene sulfonamide(ETAMBS) as an inhibitor in 1NHCl medium. The potentiodynamic polarizationstudies demonstrated the mixed mode of inhibitive action of the compound.The parameters like charge transfer resistance, double layer capacitance,surface uniformity and relaxation time derived from impedance analysisconfirmed the effective performance of the inhibitor. The mode of adsorption ofETAMBS on mild steel surface was well demonstrated from quantum mechanicalfunctions such as HOMO, LUMO, Hardness, softness, energy gap and dipolemoment. The formation of protective film of the compound was proved by SEMimages.
