Spray electroplating

Spray electroplating is a surface coating process that is widely used in the metalworking industry. This process makes it possible to provide metal parts with a thin, even and corrosion-resistant protective layer by spraying metallic coating materials onto the surface of the workpiece.

The spray electroplating process begins with the preparation of the workpiece, which is cleaned of impurities and, if necessary, pre-treated to improve the adhesion of the coating. The coating material, typically an alloy of zinc, aluminum or zinc-aluminum, is then sprayed onto the workpiece in the form of fine particles. This is done using a spray gun, which applies the coating material to the surface of the workpiece under pressure.

The impact of the particles on the surface of the workpiece creates a protective layer that bonds firmly to the substrate. This coating not only provides protection against corrosion, but can also offer additional functional properties such as improved hardness, abrasion resistance or electrical conductivity, depending on the specific requirements of the application.

A key advantage of spray electroplating is its versatility and flexibility. It can be applied to a variety of materials such as steel, aluminum, copper and their alloys, making it a widely applicable coating method. In addition, the process is comparatively inexpensive and requires less extensive preparatory work compared to other electroplating processes such as dip electroplating.

Due to its efficiency, versatility and the high quality of the coatings produced, spray electroplating is used in various industries, including the automotive, construction, electronics and aerospace industries. It offers a reliable solution for improving the surface properties of components and helps to extend their service life and functionality.
