Cyclic voltammetry

Cyclic voltammetry is an electrochemical analysis technique used in surface technology to obtain information about the electrochemical properties of material surfaces. This method enables the investigation of redox reactions and the characterisation of the electrochemical activity of materials.

During cyclic voltammetry, an electrical voltage is applied to an electrode and the resulting current is measured as the voltage is varied in a cyclic pattern. Typically, the cycle involves applying the voltage in ascending and descending directions, resulting in a characteristic current-voltage diagram known as a voltammogram.

In surface engineering, cyclic voltammetry is used to obtain information about various electrochemical processes, including redox reactions on the surface of coatings, corrosion behaviour of materials and the effectiveness of corrosion protection coatings. This technique provides insights into the electrochemical stability, reactivity and other important parameters of material surfaces.

Cyclic voltammetry is used in various areas of surface technology, from the development of new coating materials to the characterisation of metal surfaces in corrosion research. Through the detailed analysis of electrochemical reactions, cyclic voltammetry contributes to a deeper understanding of surface properties and the optimisation of materials and coatings.
