Some aspects of oil lubricant additivation with ZnO nanoparticles [PDF]

, 2006
This is a study on the tribological behaviour of ZnO nanoparticles as an additive in a polyalphaolefin (PAO6) and on the influence of dispersing agents (OL100 and OL300). Antiwear and extreme pressure tests were run on two four-ball machines. Firstly, it

Extruded and injection moulded virgin PA 6/6 as abrasion resistant material [PDF]

, 2017
Polyamide (PA6/6) is often used as a tribological pair in abrasion prevalent applications such as hinges and sliders. PA6/6 is frequently processed by injection moulding and extrusion process.

Particle traps constructed on the insulator of conductive slip rings for surface flashover mitigation under particle adhesion

AIP Advances
The generation of abrasive particles is an unavoidable consequence of sliding electrical contact wear in conductive slip rings (SRs). The adhesion of abrasive particles to the insulators may lead to a decrease in flashover voltage, posing a risk to ...

Particle Technology in Chemical Mechanical Planarization

KONA Powder and Particle Journal, 2014
In order to keep pace with Moore’s law, multilevel metallization has become the process of choice. Having a planar wafer surface before every successive step in multilevel metallization is important. The Chemical
