Product details

The main component of hydrogen-containing Diamond-like Carbon (DLC) coating is carbon, which is a kind of amorphous hard film with high hardness and excellent frictional properties. It is composed of graphite (SP2) and diamond (SP3). Because of its excellent friction properties, it is widely used in industry. Especially in the absence of lubricants, the friction coefficient is also very low (0.005 ~ 0.2).

Hydrogen-containing Diamond-like Carbon  (DLC) coating has low friction coefficient, good adhesion resistance, high hardness and excellent wear resistance.

SP3 diamond carbon atoms in space constitute a continuous, solid skeleton structure, so hard, into a regular octahedral lens.

SP2 The carbon atoms of graphite have a flat layered structure, and the interaction between layers is small, so it is very soft, conductive, and slippy scaly structure

This kind of Diamond-like  Carbon (DLC) coating is usually obtained from hydrogen-containing (H) gases such as acetylene C2H2 and methane CH4 through PECVD. Moreover, it can be obtained at a low process temperature, the lowest process temperature can be lower than 80°C, which can effectively solve the thermal deformation of materials and other defects.
