Plasma polishing

Plasma polishing is an electrochemical process for smoothing and polishing metallic surfaces. The workpieces are immersed in an electrolyte in which they act as an anode, while an opposite pole serves as a cathode. Applying a voltage creates a plasma that evenly removes the surface microstructure of the metals, creating a smooth and shiny surface.

This method is particularly suitable for complex geometries and hard-to-reach areas that are difficult or impossible to reach with mechanical polishing methods. Compared to traditional polishing methods, plasma polishing offers numerous advantages, such as improved surface quality, reduced roughness and the removal of microscopic burrs. This not only improves the aesthetic appearance of the workpieces, but also their functionality, as smoother surfaces often lead to better material properties such as corrosion resistance and fatigue strength. Plasma polishing is also more environmentally friendly as it does not use abrasive materials or chemicals that would have to be disposed of.
