Galvanic potential

The galvanic potential is a physical concept used in electrochemistry and refers to the electrical potential that arises between two different metals or materials when they are immersed in an electrolytic medium. This phenomenon plays a crucial role in various industrial applications, especially in the context of galvanic processes such as electroplating.

The galvanic potential is created by the different electrochemical properties of the materials involved. When two different metals come into contact with each other and are immersed in an electrolytic medium, electrons can flow between the metals. This flow of electrons generates an electrical potential, which is referred to as the galvanic potential.

The electroplating potential has important effects on the electroplating processes, especially on the quality and durability of the applied coating. In electroplating, a common application, the electroplating potential can influence the adhesion and uniformity of the applied metal layer.

In practice, the electroplating potential is often controlled by selecting suitable combinations of metals and coating materials. The use of materials with similar electrochemical properties can help to minimize the electroplating potential and thus improve the quality of the electroplated coating.

It is important to consider the electroplating potential when designing components or selecting materials for electroplating processes to avoid undesirable effects such as corrosion, delamination or other quality issues. By precisely controlling the electroplating potential, industrial applications can be optimized and the performance of electroplating processes can be improved.
