Abstract
The inhibitive action of inhibitor used (NHETP) on corrosion of stainless
steel in 2 M HCl solution was investigated through weight loss and
electrochemical techniques. Polarization measurements indicate that all
the examined compounds act as a mixed inhibitor and inhibition
efficiency increases with inhibitor concentration. Maximum inhibition
efficiency (99%) is obtained at 5x10-4 M NHETP inhibitor. Inhibition
efficiency increases in the order: NHETP > AMORPH > NMEP. Also,
inhibition mechanism and thermodynamic parameters are discussed.
