Diamond-like carbon
Encyclopedia : D : DI : DIA : Diamond-like carbon
Diamond-like carbon (DLC) (also known as tetrahedral amorphous carbon, or ta-C) is a term which covers a class of amorphous carbon materials containing a significant amount of sp3 hybridized carbon atoms. DLC can be synthesized as thin films using ion beam deposition or sputter deposition. Depending on the sp3 to sp2 hybridization ratio (>60%) DLC films can appear transparent, possess high hardness, and be electrically insulating.
DLC is an industrially important material, which is used as a coating on hard-disk platters and hard-disk read heads to protect against head crashes.
