- CVD chemical vapor deposition
- PVD plasma vapor deposition
- thin corrosion and wear protection layers based on oxide or hard material can be applied, especially in mass production.
- Electrochemical or galvanic processes are also used.
- Thermal spraying mainly creates layers with a layer thickness of more than 0.1 mm.
