SELGA-COAT® is a special process used for the selective coating of mechanical parts. Defined surface areas (functional surfaces) are treated in a closed electrolyte circulation system. Any parts of a component that do not need to - or that shall not - be coated are covered in a special tooling with integrated sealing systems.
SELGA-COAT® layers, compared to conventionally produced coatings, have substantially improved properties, such as e.g.
- Thickness tolerances: up to ± 2 µm
- Little roughening
- Corrosion and wear resistance
- Electrical insulation
The layer properties depend on the base material and the SELGA-COAT® variant that is used for the selective coating.
