Abstract
The effects of L-Lysine on stainless steel 316L corrosion in Ringer’s solution were investigated. The investigation comprised different electrochemical techniques: measurement of open circuit potential and linear potentiodynamic polarization. The results obtained by polarization measurements show that the L- Lysine successfully inhibits the corrosion processes on stainless steel, in Ringer’s solution, acting like mixed type inhibitor with a more pronounced influence on cathodic processes. Also, potentiodynamic curves indicate that L-Lysine acts through adsorption onto the steel surface without changing the mechanism ofcorrosion of steel. Quantum chemical parameters indicate that L-Lysine may be used as a corrosion inhibitor which was confirmed by electrochemical measurements.
