Calculations of the impact of friction and wear on energy consumption, economic
expenditure, and CO 2 emissions are presented on a global scale. This impact study covers …

This review summarizes recent advances in the area of tribology based on the outcome of a
Lorentz Center workshop surveying various physical, chemical and mechanical phenomena …

The adhesive wear process remains one of the least understood areas of mechanics. While
it has long been established that adhesive wear is a direct result of contacting surface …

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

In tribology, a considerable number of computational and experimental approaches to
understand the interfacial characteristics of material surfaces in motion and tribological …

Tribochemistry, the study of chemical reactions in tribological interfaces, plays a critical role
in determining friction and wear behavior. One method researchers have used to explore …

A gradient nano-grained (GNG) surface layer is fabricated on a commercial-purity Cu
sample, in which a significant reduction in the coefficient of friction and the wear loss is …

Frictional sliding induces a distinct discontinuity in the microstructure between a subsurface
layer and the underlying bulk material, which strongly influences the tribological …

Whether a graphitization mechanism can control the low-friction behavior of DLC films is still
controversial. In this paper, we establish the molecular dynamics model of the DLC film with …

Tailoring the surface properties of a material for low friction and little wear has long been a
goal of tribological research. Since the microstructure of the material under the contact …
