Flade potential

The Flade potential is an electrochemical term that refers to the electrical potential of an electrode in an electrolytic medium. This potential plays a decisive role in the evaluation of corrosion behavior and protective measures for metallic surfaces.

The Flade potential is specific to each material and depends on various factors, including the chemical composition of the electrode, the properties of the electrolyte and the environmental conditions. It represents the electrochemical equilibrium at the interface between the electrode and the electrolyte.

With regard to corrosion, the Flade potential is important as it has an influence on a metal's tendency to corrode. A lower Flade potential indicates a higher susceptibility to corrosion, while a higher Flade potential indicates a lower susceptibility to corrosion. This concept is crucial for the development of protective measures, as it enables the selection of appropriate methods to control the electrochemical environment in order to minimize corrosion.

In practice, the Flade potential is determined by various measurement methods to gain detailed insight into the electrochemical properties of a system. This information is of great importance to engineers and materials scientists who are concerned with optimizing materials and protective coatings to extend component life and minimize corrosion effects.
