Current density-potential curve / current voltage curve
This curve (short: SPK) represents one of the most important test methods of corrosion testing.
Typical corrosion of metals in electrolytes (i.e., an aqueous medium) involves electrochemical reactions associated with conduction exchange that occurs at the boundary between an ionic conductor, the electrolyte, and the electrical conductor, the metal.
The calomel electrode is a common reference electrode; it is coupled to the experimental electrode via an intermediate vessel containing saturated KCl solution. To make a measurement that is close to potential, a Haber-Luggin capillary is used. Its opening is found directly on the electrode.
The values obtained are recorded in a coordinate system.
