Diamond Like Coating Process

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.

Diamond like coating process.

During the dlc coating phase of the process a carbon carrying gas is introduced into the chamber. If no underlayer is required a dense uniform coating of dlc can be deposited directly to the substrate as well. In these types of environments only the high hardness of a dlc coating along with a corresponding low coefficient of friction. An adhesive diamond coating on this category of substrate without an interlayer is almost ruled out by the scientific community.

Calico diamond like carbon dlc is a dense metastable form of hydrogenated amorphous carbon a c h containing significant sp3 bonding. 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. All seven contain significant amounts of sp 3 hybridized carbon atoms.

Within the universe of wear resistant thin films diamond like carbon dlc coatings have emerged as the ideal solution for demanding physical applications where components are under high loads or subject to extreme friction wear and contact with other parts. The reason that there are different types is that even diamond. Diamond like carbon dlc coatings exist in several different forms of amorphous carbon materials that display some of the unique properties of diamond. This process of bonding carbon and hydrogen confers valuable diamond like properties such as mechanical hardness low friction optical transparency and chemical inertness.
