The Role of Counter-Face Roughness on the Tribological Performance of a Clutch System Tested with a Pin-On-Disc Tribometer

Lubricants, 2016
This study was a continuous investigation of the roles played by the tribofilm on dry automotive clutch system performance. Tribological experiments were performed by the addition of wear debris at the beginning of tribometer tests and by reducing the ...

The effect of S/Mo ratio on structure and properties of MoSx-Ti composite coatings deposited by magnetron sputtering

Materials Research Express, 2020
MoS _x -Ti composite coatings with different S/Mo ratios were prepared by varying the substrate bias voltage of magnetron sputtering. It was found that the S/Mo ratio of the as-deposited MoS _x -Ti coating decreased gradually from 1.7 to 1.3 as substrate

ZDDP tribofilm formation under various rubbing conditions

, 2018
ZDDPs (zinc dialkyldithiophosphates) have been widely used as antiwear additives in engine oil for the last 70 years. Initially, since engine parts were manufactured from cast iron, ZDDPs were required to protect them by forming tribofilms on the surfaces of this material.

Modelling of wear and tribofilm growth

, 2012
Wear is a consequence of nature which becomes costly if uncontrolled. Basic wear protection is provided by lubrication which will decrease the severity of the contact between asperities. If the conditions of a contact are such that there can be no hydrodynamic lift off by the oil and most of the contact occurs in between such asperities, the protection
