Characteristic of the arc coating process:
LARC® (LAteral Rotating Cathode) and CERC® (CEntral Rotating Cathode) are PLATIT’s proprietary brand names for rotating cylindrical cathodes with arc technology in the chamber door and in the middle of the coating chamber.
Compared to conventional cathodes, rotating cathodes have several advantages:
Characteristic of the sputter coating process:
To achieve high deposition rates during sputtering, our Pi411 PLUS SCIL® uses the patented SCIL® (Sputtered Coating Induced by Lateral Glow Discharge) process. SCIL® enables high-power sputtering from the central cathode.
The cathode consists of these elements:
This unique combination achieves unimagined benefits:
The Pi411 PLUS LACS® coating unit allows you to use two different types of this hybrid technology.
1. Simultaneous deposition by LGD® and SCIL®
To increase ion density and influence coating properties of sputtered coatings, you can use Lateral Glow Discharge and Sputtered Coating Induced by Lateral Glow Discharge simultaneously.
The setup is as follows:
2. Simultaneous deposition by LARC® and SCIL®
For targeted doping of coating components, it is convenient to combine arc evaporation with LAteral Rotating Cathode and cathode sputtering with Sputtered Coating Induced by Lateral Glow Discharge.
The setup is as follows:

Arc coating and sputter coating refer to two methods used to release ions from so-called “targets” in order for them to condensate (“deposit”) onto a material in a PVD unit, with which it forms a coating. The arc process uses an electric arc, i.e., a strong electrical discharge, comparable to lightning, which permanently strikes the target. In the sputtering process, on the other hand, the target is bombarded with high-energy ions (“cathode sputtering”), which causes the ions to detach from the target.
Both processes operate in a vacuum chamber under high vacuum, i.e., at a very low pressure. The hot gas (“plasma”) formed from the electrically charged molecules leads to a layer on the coated objects. Thus, the technical term for these coating processes is also “Physical Vapor Deposition” (PVD). The properties of the layers are influenced by the evaporated materials.
Arc processes are often used for tools that are made more resistant by hard coatings.
Sputtering processes are often used for functional components, decorative or medical parts and instruments.
