The reason that there are different types is that even diamond.
Diamond like carbon coating process.
Dlc exists in seven different forms.
Dlc coatings can be amorphous more or less flexible hard strong and slick according to the composition and processing method.
The choice of technology and deposition parameters allow for a wide variety of performance characteristics including hydrogenated and non hydrogenated dlc coatings.
Among pvd pacvd coating compositions and technology dlc coatings stand out as a distinctive category.
Dense smooth a c h dlc diamond like carbon coating.
All seven contain significant amounts of sp 3 hybridized carbon atoms.
This process of bonding carbon and hydrogen confers valuable diamond like properties such as mechanical hardness low friction optical transparency and chemical inertness.
Calico diamond like carbon dlc is a dense metastable form of hydrogenated amorphous carbon a c h containing significant sp3 bonding.
Diamond like carbon dlc coatings can be deposited by different technologies such as pvd arc pvd sputtering and pacvd processes.
This gas is the source for the amorphous carbon dlc coating.
Diamond like carbon dlc coatings exist in several different forms of amorphous carbon materials that display some of the unique properties of diamond.
If no underlayer is required a dense uniform coating of dlc can be deposited directly to the substrate as well.
