Diamond-Like-Carbon (DLC) Coating
Reduce friction, wear, fretting, galling and corrosion with environmentally friendly DLC coatings
DLC Coatings - Diamond-Like Carbon
Diamond-Like Carbon (DLC) coatings can be deposited by different technologies such as PVD arc, PVD sputtering and PACVD processes. The choice of technology and deposition parameters allow for a wide variety of performance characteristics, including hydrogenated and non-hydrogenated DLC coatings.
DLC coatings are environmentally friendly and can be used to reduce friction, wear, fretting, galling and corrosion. They can also be used to modify electrical conductivity and wettability. Due to the attractive colors of DLC coatings (ranging from anthracite to deep black), they are often applied in decorative applications such as watchmaking, jewelry, kitchen and bath hardware, automotive interiors, firearms and other fields, combining both aesthetics and performance.
Get in touchWhat is a Diamond-Like-Carbon (DLC) Coating?
DLC coatings offer a unique combination of high hardness and low friction coefficient → ‘the hardness of diamond and the lubricity of graphite’.
We are thus able to engineer DLC coatings to make them harder like diamond or softer like graphite – according to the requirements that a specific application demands.
Furthermore, DLC coatings can be doped to include metallic elements and can include multi-layered structures that further enhance the performance and flexibility of such coatings.
