Corrosion inhibitors play a major role in the cost effective control of corrosion. Because of the toxic nature and high cost of chemicals plant extracts are currently used as inhibitors. In the current study, efforts are taken to study the role of seed extracts of Phaseolus aureus on corrosion of mild steel in 1M HCl by weight loss method and potentiodynamic polarization technique. The Potentiodynamic polarization results reveal that the seed extract behaved like mixed type inhibitor. Maximum inhibition efficiency of Phaseolus aureus in 1M HCl was found to be 93%.
