摘要：
Inhibiting effect of cetyl trimethyl ammonium chloride (CTMAC) and cetyl trimethyl ammonium bromide (CTMAB) on the corrosion of mild steel in 1 M HCI solution have been studied using three different techniques (weight loss, electrochemical polarization studies and surface study by SEM). Weight loss studies were conducted in 1 M HCI at different temperatures (25 degrees, 35 degrees & 45 degrees C) using various concentrations (50-250 ppm) of inhibitor for 24 h immersion time. Inhibitor efficiency (IE) increases with increase in inhibitor concentrations (50-250 ppm) at a given temperature and time. IE was found to vary with concentration, temperature and immersion time. Electrochemical polarization result revealed that CTMAC and CTMAB were mixed type inhibitors.
