Abstract
N-benzyl piperidine -4- one oxime (BPOX) was tested as corrosion inhibitor for mild steel in 2M HCl solution using electrochemical and weight loss measurements. Results obtained showed that this compound has a good inhibiting properties for mild steel corrosion in acidic medium, with inhibition efficiencies values reach 77% at 300ppm. The inhibition was assumed to occur via adsorption of the BPOX molecules on metallic surface. Adsorption of inhibitor molecules on mild steel surface showed Temkin’s adsorption isotherm fit in acidic media. Potentiodynamic polarization curves showed that the inhibition is a mixed nature. In addition, results obtained by weight loss and electrochemical measurements are in good agreement. Mechanism of physical adsorption is proposed from the apparent activation energy (Ea) and the thermodynamic parameters obtained. The adsorption of the BPOX on the mild steel surface is spontaneous.
