The diamond-like term reflects that the film (coating) contains some portion of sp3 (diamond) and sp2 (carbon) bonding. This bonding has mechanical properties of the film different from the properties of a diamond. The diamond-like carbon (DLC) is an amorphous carbon material that displays some of the typical properties of a diamond.

It is a thin film coating deposited on other materials to impart essential properties of diamond such as hard, chemical & scratch resistance, and to provide surface lubrication to minimize friction amongst others. DLC coatings possess high thermal conductivity and electrical resistivity that make them suitable for medical devices, micro-electronics, and automotive components applications. Protective coatings on displays, flexible semiconductors, and sensors are coated with DLC to increase the durability of the product and increase overall product life.

DLC coating is deposited on any material by the 'Plasma-enhanced Chemical Vapor Deposition (PE-CVD)' process. Polymers are often known to have low melting point temperatures, therefore coated with DLC to improve their melting point temperatures and surface hardness.

The polymers like PET (Polyethylene Terephthalate) is one of the major product coated with DLC to impart strength and have an extended product life. The structure and mechanical properties of DLC are based on the method of deposition and incorporation of additional elements like hydrogen, nitrogen, silicone, and other metal dopants.

These additional elements control the hardness of the resultant film, level of residual stress, and tri-biological properties. The DLC coating is chemically inert and can be used for number of materials like aluminum-silicon alloys, powder metallurgy, cylinders, pistons, balls, gates, actuators, crankshafts, ball bearings, rotors, and impellers amongst many others.

The major restraining factor with the usage of DLC is that the coating thickness (5 m and below) is limited. Since the film itself is under the influence of residual stresses, de-lamination failure can occur in case of high film stress. Lower temperature degrades the DLC to graphite is another factor restraining the growth.

The property of graphite is not similar to diamond and hence the coating may not be worthy enough to impart desired properties. In recent years there has been an increased focus to apply DLC films on mass-produced mechanical components including medical components. This is one of the major factors that is expected to propel the market growth for DLC coatings and their applications.
