DLC Coatings

Diamond Like Carbon (DLC) coatings, a new technological advancement of PVD + PECVD coatings, has been widely successful in the commercial industry. Calico's carbon-based coating has extreme hardness due to the diamond crystal structure and is soft and lubricious due to the graphite crystal structure. Combining these two structures reduces the coefficient of friction by 200%-500% compared to traditional tribological PVD coatings. Our DLC coatings are generally amorphous (without typical crystal structure) and can be deposited using an expansive range of processes with elements like hydrogen and metals such as chromium. These integral components and techniques have an outstanding impact on the properties and structures of the DLC coating.

The properties of DLC coatings in terms of increased hardness, coefficient of friction, roughness, adhesion level, load carrying capacity, resistance to humidity influenced degradation, fatigue tolerance, etc. can be personalized over a varied range depending upon deposition parameters, deposition technology and the combination of materials making up the DLC coating. Calico's Diamond Like Carbon (DLC) coatings are in a dense, metastable form of hydrogenated amorphous carbon (a-C:H) containing significant SP3 bonding.
