HCA Puls
Pulsed high-current arc (HCA) with plasma filter HCA technology (PVD coating) The cycle time of the production plant is in the seconds range. The coating time itself is under 1 second. The vacuum arc is a rather simple coating method. Unfortunately, liquid drops of the target material deposit as so-called droplets, and the only possible way to avoid these droplets is to filter them out. While it is possible to filter the droplets in strong magnetic fields, it also causes …
