ELECTROCHEMICAL CORROSION TESTING

pOTENTIODYNAMIC ACCELERATED EVALUATION

corrosion labFor service environments where standard pass/fail exposure testing is insufficient, electrochemical corrosion testing offers a more advanced analysis. Testing is performed through a controlled electrochemical reaction between two materials, or between an exposed surface and its surrounding environment.  The introduction of a voltage current to the testing setup rapidly accelerates the effect of the aqueous solution on the material. Therefore, targeted electrolyte solutions can be used to simulate long-term conditions and predict and characterize the corrosive properties of metal materials and components

Applications of Electrochemical Corrosion Testing

  • Evaluation of finished medical devices for pitting, crevices, and corrosion susceptibility
  • Comparison of raw materials (screening) for corrosion characteristics
  • Evaluating effects of passivation or surface modifications on corrosive behavior
  • Evaluating/comparing processing effects on corrosion properties
  • Evaluating bi-metal combinations for galvanic corrosion behavior
