Corrosion tests
To describe the corrosion properties of the material, a 7-day exposure was performed, extended by non-destructive electrochemical measurements: open circuit potential (OCP), electrochemical impedance spectroscopy (EIS) and polarization resistance (RP), in a complex body simulation, i.e. in EMEM M7278 with 5% FBS (Foetal Bovine Serum, Sigma Aldrich) and the necessary addition of 1% antibiotics/antimycotics (all Sigma Aldrich) at 37 C. Cylindrical samples 10 mm high and 4.3 mm in diameter were ground (to FEPA P2500), washed with demi-water and degreased in ethanol, mounted on a PTFE (Polytetrafluoroethylene) holder immediately before measurement. Subsequently, the samples, together with glassy carbon rods and a 75 ml polymethylpentene cell, were sterilized using UV-C (ultraviolet light in the wavelength range of 100 to 280 nanometers (nm). Afterwards, the measuring cell was assembled and an ethanol-washed silver-chloride reference electrode (SSCE - Silver/Silver Chloride Electrode, 3 mol/KCl) was added. During the subsequent exposure, OCP was acquired, intermittently by RP measurement (+-15 mV/OCP, 0.125 mV/s) or EIS (60 kHz ? 0.01 Hz, 7 points per decade, EAC 15 mV.rms, EDC=OCP). Measurements were performed on a Gamry Reference 600 potentiostat, the correctness of the impedance data was verified by Kramers-Kronig transformation in Gamry Echem Analyst software, and subsequent evaluation was performed in ZView software.
