Electrolytic Corrosion Testing
In addition to the classic exposure testing of materials in corrosive media, we offer electrolytic corrosion investigations based on electrochemical methods such as open circuit potential measurements, potentiodynamic polarisation (linear or cyclic voltammetry), electrochemical impedance spectroscopy or Scanning Kelvin Probe measurements.
Larger components and samples can be tested in a practical manner in the salt spray chamber. Classic corrosion testing methods in electrolytes, such as the Strauss test, Huey test, Jones test or similar tests are also offered. An extensive range of equipment with various potentiostats, test setups and additional devices is available for serving your specific testing demands.
