Passivated Surfaces you can rely on
A good passivated surface decreases/eliminates heavy metal ion release and improves corrosion resistance, thereby reducing negative tissue reactions. It improves biocompatibility of medical products like stents and heart valve frames.
Electrochemical Impedance Spectroscopy (EIS) is applied to measure the polarization resistance (Rp) of a corroding system.
Potentiodynamic polarisation corrosion tests determine the susceptibility for uniform, pitting and crevice corrosion.
