摘 要: 固体超滑是指相互接触的滑动固体表界面间摩擦系数极低(10 量级或更低)的现象，因此，开展固体超滑理

Abstract: Solid superlubricity describes the state that coefficient of friction is lower than 10 between two sliding
interfaces. The development of solid superlubricity mechanism and superlubricity technology are of great significance.
Diamond-like carbon films (DLC) superlubricity is heavily relied on the passivation of the introduced heteroatoms
(hydrogen), especially when the content of hydrogen is higher than 40%. However, carbon films with high hydrogen
content are just a fraction according to ternary phase diagram of DLC films. A large number of passivated or less
passivated carbon films are lack of theoretical guidance in achieving superlubricity. Under the basic of latest progress at
home and abroad, this review proposed the rolling-sliding mechanism towards disordered and unpassivated or less
passivated carbon films, which includes sliding mechanism, rolling mechanism and rolling-sliding mechanism.
Furthermore, the possible development tendency and design principles and programs of solid superlubricity were
discussed.
Key words: diamond-like carbon film; superlubricity; sliding mechanism; rolling mechanism; graphene; onion-like
carbon
