Definition - What does Galvanostatic mean?
Galvanostatic refers to an experimental technique whereby an electrode is maintained at a constant current in an electrolyte. This technique is used to measure corrosion rate and electrochemical reactions.
Galvanostatic, like potentiostatic and potentiodynamic, is a polarization technique that allows for the controlled polarization of metal surfaces in electrolytes, in order to directly observe cathodic and anodic behaviors.
In galvanostatic tests, the change is plotted in potential verses time at constant current. A constant DC current is applied to the metal of interest while it is immersed in the electrolyte.
