The friction and wear behavior of materials are not intrinsic properties, but extrinsic
properties; in other words, they can drastically vary depending on test and environmental …

The tribological study of materials inherently involves the interaction of surface asperities at
the micro to nanoscopic length scales. This is the case for large scale engineering …

Highly sp 3-bonded, nearly hydrogen-free carbon-based materials can exhibit extremely low
friction and wear in the absence of any liquid lubricant, but this physical behavior is limited …

Diamond and diamondlike carbon (DLC) films exhibit a wide range of sometimes
contradictory tribological behavior. Experimentally, isolating the influences of factors such as …

Amorphous carbon is one of the most lubricious materials known, but the mechanism is not
well understood. It is counterintuitive that such a strong covalent solid could exhibit …

The tribological behavior of electrodeposited Zn–Ni alloy coatings was investigated for its
suitability to replace Zn-and Cd-based coatings. An in situ tribometry technique with a …

Nanocrystalline diamond (NCD) films with a thickness of~ 6 µm and average grain sizes
ranging from 60 to 9 nm were deposited on silicon wafers using a hot-filament chemical …

The oxidized layers at the surface of hydrogenated diamond-like carbon (H-DLC) were
studied with X-ray photoelectron spectroscopy, near-edge X-ray absorption fine structure …

An in situ tribometer utilizing a transparent hemispherical counterface was used to conduct
sliding wear tests on Al-Al2O3 composite coatings deposited by cold spray. Direct …

Silicon containing diamond-like carbon films is of value for engineering applications
operating at the temperature above 200° C. This work presents a Si-gradually doped …
