The main purpose of this study was to evaluate physicochemical and electrochemical properties of AISI 316L stainless steel with modified surface, used for implants in human urinary system. In order to simulate conditions, which occur in the tissue environment of the urinary system, the test pieces were exposed in a urinary solution at temperature of T=37 ±1ºC, for a period of 30 days. Evaluation of physicochemical properties of biomaterial was made on the basis of surface chemical analysis (XPS). To evaluate the effects which occur on the surface of the examined steel, Electrochemical Impedance Spectroscopy (EIS) method was also employed. Analysis of test results shows favourable influence of the suggested surface treatment of AISI 316L stainless steel. Samples having electrolytically polished and chemically passivated surface featured the best physicochemical and electrochemical characteristics.

Plasma Immersion Ion Implantation

Plasma immersion ion implantation (PIII) of nitrogen is low-temperature surface technology which enables the improvement of tribological properties without a deterioration of the corrosion behavior of austenitic stainless steels. In this paper the corrosion properties of PIII-treated AISI 316L stainless steel surfaces are evaluated by electrochemical impedance spectroscopy (EIS), potentiodynamic polarization (PP) and exposure immersion tests (all carried out in the 0.9 wt. % NaCl solution at 37 ± 0.5 °C) and compared with a non-treated surface. Results of the three performed independent corrosion tests consistently confirmed a significant increase in the corrosion resistance after two doses of PIII nitriding.
