Tribology is the study of interactions between surfaces or interfaces in relative motion
(“tribos” means “to rub” in Greek). It includes the phenomena of friction, adhesion, and wear …

Graphene has attracted enormous attention in the field of lubrication based on its excellent
physical and chemical properties. Although many studies have obtained thermally or …

Hydrogenated amorphous carbon (aC: H) is capable of providing a near-frictionless
lubrication state when rubbed in dry sliding contacts. Nevertheless, the mechanisms …

Macroscale superlubricity breakdown of lubricating materials caused by substrate surface
roughening and mechanochemical modification poses great challenges for their practical …

The interface of two contacting materials experiences complex physical and possibly
chemical reactions when one slides with respect to another. While tribology, a subject …

To improve the thermal stability and mechanical performances of the DLC coating at high
temperature, thermodynamically stable Si-N and CN bonds were introduced into the DLC …

After the rapid growth in the use of CoCrMo metal-on-metal hip replacements since the
second generation was introduced circa 1990, metal-on-metal hip replacements have …

Understanding atomic-scale wear is crucial to avoid device failure. Atomic-scale wear differs
from macroscale wear because chemical reactions and interactions at the friction interface …

Driven by the advent of fullerenes, carbon nanotubes and graphene, designing or tailoring
sp 2-rich carbon clusters in carbon based films attains very interesting properties which can …

The lubrication of diamond-like carbon (DLC) films has commonly been ascribed to two
hypotheses, ie,'friction-induced graphitization'mechanism and passivation mechanism. To …
