Voltametry

Voltametry is an analytical method widely used in surface technology to characterize electrode processes and determine the chemical composition of material surfaces. This technique is based on measuring the current flowing through an electrode while systematically varying its potential.

In surface technology, voltametry is often used to obtain information about electrochemical processes that occur during the coating, cleaning, passivation or corrosion of surfaces. By recording current-potential curves, various parameters such as reaction kinetics, adsorption of species on the surface and dissolution kinetics can be investigated.

An important aspect of voltametry in surface technology is the ability to evaluate the efficiency and selectivity of coating processes. By measuring current-potential curves, optimizations can be made to ensure a uniform coating on the surface and minimize unwanted side reactions.

In addition, voltametry enables the identification and quantification of impurities or foreign particles on the surface of materials. This is particularly important for applications where the highest purity requirements apply, such as in the electronics or semiconductor industry.

Voltametry is therefore a powerful tool in surface technology that enables electrochemical processes to be characterized, coating processes to be optimized and the quality of treated surfaces to be improved. Through the precise control and analysis of electrochemical parameters, voltametry contributes significantly to the development and improvement of surface coatings.
