DLC film formation utilizes technologies such as PVD (Physical Vapor Deposition) and CVD (Chemical Vapor Deposition). Ion source deposition is a type of PVD where a filament is heated to ionize hydrocarbon gas using thermal electrons, which then collide with the substrate under a potential difference to create a coating. PCVD (Plasma Chemical Vapor Deposition) involves ionizing hydrocarbon gas in a plasma region and colliding it with the substrate under a potential difference to form a coating. FAD (Filtered Arc Deposition) uses a magnetic field filter to draw only ionized carbon into the substrate for film formation. [Film formation methods we employ] ■ Ion source deposition ■ PCVD (Plasma Chemical Vapor Deposition) ■ FAD (Filtered Arc Deposition) *For more details, please refer to the related links or feel free to contact us.
