DLC (Diamond Like Carbon) coating is the most advanced surface treatment technology now.
DLC coatings are formed when ionized and decomposed carbon or hydrocarbon species land on the surface of a substrate with energy typically 10-300eV. DLC films are generally amorphous (i.e have no dominant crystalline lattice structure) and consist of a mixture of sp2 (graphite) & sp3 (diamond) phases. Control of film properties is strongly dependent on the flux characteristics of the chosen deposition technique (PVD sputter or evaporation and Pa-CVD), metal and hydrogen content within the film, sp2:sp3 ratio, substrate bias voltage, ion energy and ion density as well as substrate temperature.
KinsDLC coating, including DB-DLC, F-DLC and Du-DLC three series, have many excellent and unique properties:
1. Mechanical and tribological properties: super high hardness and elastic module, very low friction coefficient, self-lubricant,solid lubricant, extremely wear resistant and scratch resistant, smooth and very low roughness;
2. Chemical properties: chemical inertness, chemical stability, corrosion resistant, anti tarnish;
3. Surface properties: anti fingerprint, anti-stick, tuneable surface hydrophobic and hydrophilic, bio-compatibility;
4. Thermal properties: high thermal conductivity;
5. Electrics properties: high electric resistance, insulating protection;
6. Optical properties: anti-reflective, high absorption rate, excellent optical properties;
7. Decorative and aesthetic properties: Kins DLC coating has brilliant beautiful appearance, the surface color is pure deep black . The color are very stable and never change, and can be completely uniform on any face of 3D substrates, the deep black color even on the matt surface, without any yellow or blue or rainbow shadow in the black film. The traditional IP black coating often has white dots in the black film, Kins DLC deep black coating never has such white dots in the film. These properties are very attractive and valueable.
KinsDLC coating can be widely used many fields:Mechinery parts, precision components, molds, cutting and forming tools, car parts, engine parts, electrics products, optical products, bio-medical products, etc.
DLC coating has also been widely used in the high-end decorative coating industry because of its brilliant deep black color, like watch parts, jewelry parts, consumer goods, mobile phone, golf club heads,ice skate blades,flat PC etc.
Uniform deep black ultra hard DLC coating can greatly increase the additional values to the high-end decorative products, and can obviously protect the products to wear and use for much longer time.
