One of the most important application areas for electroplated layers is (cathodic) corrosion protection. By applying a metallic protective layer to components that are susceptible to corrosion or exposed to the weather, their lifespan can be significantly increased. In the area of corrosion protection, metals such as nickel, copper, chrome, and zinc are used, among others.

Anodizing stands for electrolytic oxidation of aluminum and is a process for strengthening the natural oxide layer present on aluminum through anodic oxidation. Unlike traditional electroplating processes, anodizing dissolves the top layer of aluminum and converts it into aluminum oxide. The resulting oxide layer protects the underlying workpiece from corrosion.

The smallest electronic components, such as chips or connectors, present special challenges for electroplating coatings. In addition to the conductor pattern construction in the manufacturing of printed circuit boards, copper processes are used for filling blind microvias (blind holes) and metallizing through holes. Good metal distribution is necessary even with unfavorable geometry. The most important application areas are found in the automotive industry, telecommunications, and consumer goods industry, but also in the field of e-mobility.

Electroplated metal surfaces are found in all areas of daily life and are used not only for technical purposes but also for decorative ones. For this, metallic coatings made of copper, nickel, nickel alloys, chrome, silver, and gold are used, which can offer both a matte and a high-gloss appearance. The most common application areas for decorative surfaces are found in the automotive industry, in sanitary areas for items such as fittings, but also in the consumer goods industry, thus combining functionality with appealing aesthetics.
