Tribological Properties and the Current State of Tribological Investigation of Diamond-like Carbon Films

Diamond like carbon (DLC) films have attracted significant attention recently owing to the desirable properties. A review is given of the friction behavior of DLC films and of the research progress of the tribological behavior of DLC films. The ambient factors and the difference in the DLC film structure which have effect on friction behavior of DLC films are discussed. The topics for further study have been suggested as well.
