ABSTRACT

Sinapis alba as an anti-rusting agent for corrosion of stainless steel in Hydrochloric acid medium

Shwetha N, Padmalatha Rao

ABSTRACT

Protection against corrosion using Sinapis alba was studied for the corrosion control of stainless steel in 0.5M HCl. The electrochemical techniques such as potentiodynamic polarization (PDP) measurements and electrochemical impedance spectroscopy (EIS) method were used for the stainless steel protection studies. Surface morphology studies were done for the specimen immersed in the inhibitor solution and the aggressive medium. Mechanism for the corrosion inhibition was proposed. Results showed that Sinapis alba acted as mixed type of inhibitor, with maximum inhibition efficiency of 88% for the concentration of 0.1gL?1 at 323K. It got chemically adsorbed on stainless steel by obeying Langmuir adsorption isotherm. Sinapis alba emerged as an effective eco-friendly corrosion inhibitor for the corrosion control of stainless steel in HCl acid medium.
