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. | ||
