Tribological behaviour of copper oxide nanoparticle suspension [PDF]

, 2008
This work presents and discusses the tribological behaviour of nanoparticle suspensions in a polyalphaolefin (PAO6). CuO nanoparticles were separately dispersed at 0.5, 1.0 and 2.0% wt. in PAO6 using an ultrasonic probe for 2 minutes.

Orientation dependent tribological behavior of TiN coatings

Journal of Physics: Condensed Matter, 2016
The preferred growth direction of cathodic arc physical vapor deposition-produced TiN coatings changes from (1 1 1) to (2 2 0) with high voltage pulsed bias application in the presence of Ar gas. In this study, tribological properties of these coatings were investigated via reciprocating wear tests against an inert counterbody for observing the role of

Viscosity and tribology of copper oxide nanofluids [PDF]

, 2008
Nanofluids, a term proposed by Choi in 1995 [1], are composites consisting of solid nanoparticles with sizes varying generally from 1 to 100 nm dispersed in a liquid.

Tribological and Emission Behavior of Novel Friction Materials [PDF]

Atmosphere, 2020
The tribological behavior and the related airborne particles emission of three copper-free automotive friction materials are investigated. The tests were conducted using a pin-on-disc tribometer equipped with a specifically designed clean-enclosure chamber for the emission measurement. Particle number concentration from particle size 0.3 µm up to 10 µm

Microstructure and tribological property of a MXene derived from Ti3AlC2

Materials Research Express, 2022
Ti _3 C _2 layers with a layered two-dimensional structure are synthesized by immersing a precursor Ti _3 AlC _2 with hydrofluoric acid solution. The microstructure of Ti _3 C _2 layers is analyzed by SEM, XRD, Raman and AFM.
