DLC Coating

Diamond-like Carbon (DLC) is an amorphous carbon material with many material properties similar to diamonds, such as high hardness, wear resistance, and low coefficient of friction, hence the name Diamond-like. DLC coatings are hard and smooth, and are used in a wide range of commercial applications through different process methods.

Common methods for plating DLC films include Plasma-enhanced Chemical Vapor Deposition (PECVD), Ion-beam Assisted Deposition (IBAD), Sputtering Deposition , Filtered Cathodic Arc Deposition (FCAD), Pulsed Laser Deposition (PLD), etc. Generally, DLC film can achieve excellent mechanical properties by adjusting a control parameter (e.g., substrate bias, plasma density...) to control the ratio of sp3 bonds in the film, for example, the hardness can be adjusted from 10 GPa to 40 GPa.
