If no underlayer is required a dense uniform coating of dlc can be deposited directly to the substrate as well.
Diamond like coating process.
Dlc exists in seven different forms.
Dense smooth a c h dlc diamond like carbon coating.
Diamond like carbon dlc is a class of amorphous carbon material that displays some of the typical properties of diamond dlc is usually applied as coatings to other materials that could benefit from some of those properties.
Dlc coatings can be amorphous more or less flexible hard strong and slick according to the composition and processing method.
The reason that there are different types is that even diamond.
An adhesive diamond coating on this category of substrate without an interlayer is almost ruled out by the scientific community.
This process of bonding carbon and hydrogen confers valuable diamond like properties such as mechanical hardness low friction optical transparency and chemical inertness.
All seven contain significant amounts of sp 3 hybridized carbon atoms.
This gas is the source for the amorphous carbon dlc coating.
In these types of environments only the high hardness of a dlc coating along with a corresponding low coefficient of friction.
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 exist in several different forms of amorphous carbon materials that display some of the unique properties of diamond.
