Electrochemical Corrosion Testing Services

All corrosion is an electrochemical process of oxidation and reduction reactions. As corrosion occurs, electrons are released by the metal (oxidation) and gained by elements (reduction) in the corroding solution. Electrochemical corrosion testing measures and/or control the flow of electrons (current) between the sample and an electrode placed in the electrolyte solutions in the corrosion reaction. It can be used to characterize the corrosive properties and predict the service life of metallic materials used in electronics, chemical and petrochemical, construction and other industries.
