    The test solutions we provide include but are not limited to:

    • Stainless steel pitting potential test

    • Electrochemical critical pitting temperature testing

    • Potentiodynamic anodic polarization measurements

    • Potentiodynamic polarization resistance measurements

    • Corrosion rate measurement and calculation

    • Galvanic corrosion test

    • Measurement of corrosion potentials

    • Electrochemical impedance test

    • Cyclic potentiodynamic polarization measurements

    Sample requirements

    Samples for electrochemical corrosion testing must be electrical conductors and must be small enough to fit in the polarization cell. Components can be tested as a whole or as a smaller section. Metal coupons are specially prepared for some tests.

    Standards we test to

    ISO 16773Electrochemical Impedance Spectroscopy (EIS) on Coated and Uncoated Metallic Specimens
    ASTM F2129Standard Test Method for Conducting Cyclic Potentiodynamic Polarization Measurements to Determine the Corrosion Susceptibility of Small Implant Devices
