Overview of DLC film
Diamond-like carbon film (DLC Film) is a type of carbon film that possesses properties similar to diamond. Known as a hard carbon film, DLC is an amorphous carbon material with a diamond-like structure. While the DLC process is more mature than diamond film production, DLC still boasts a range of excellent properties.
- Mechanical properties: DLC films exhibit high hardness and friction resistance, making them ideal for mechanical tools, extending the service life of devices.
- Corrosion resistance: DLC films have high chemical inertness, acting as a protective layer to prevent chemical reactions between the substrate and external elements.
- Optical properties: DLC films have a refractive index between 1.5 – 2.3, with less than 1% absorption in the infrared band, resulting in high transmittance.
- Thermal performance: As high thermal conductivity insulators, DLC films can serve as heat dissipation substrates for high-power electrical components, improving device stability.
With these outstanding qualities, DLC films have a broad range of applications in electronics, machinery, optics, and biomedicine.
