Sažetak
In vitro electrochemical behavior of commercial AISI 316L orthopedic nails was studied in simulated body fluids (physiological solution with different concentrations of lactic acid). Accelerated corrosion measurements were performed in stagnant electrolyte at 37 °C, while SEM enabled the observations on surface morphology changes due to pitting phenomena. Lactic acid changed the electrochemical behavior of steel so that passive film-breakdown started at less noble potentials than in solution without it. The lowest breakdown potential was registered in solution with 0.4 wt. % lactic acid, suggesting the detrimental effect on pitting corrosion resistance of orthopedic implants.
