Lubricated Sliding

The friction and wear of ceramics under lightly-loaded, marginally-lubricated sliding-contact conditions are reviewed. The mechanism of ceramic friction and wear and the factors influencing them in these situations are identified and discussed with reference to the results presented in the literature. The implications to slider-material and thin-film rigid-disk overcoat material selection in magnetic recording devices are discussed.

Lubricated Sliding

The current study investigated the effect of micro-dimple size on reduction friction to understand the potential of friction reduction through micro-scale dimple to fabricate by photolithography on pin-on-disk test using flat-on-flat contact geometry. It was verified that the friction property with respect to the same pitch influences the size of dimple under lubricated sliding contact. Additionally, it was recognized from Stribeck curve that the friction property has a connection with the size of dimple. This can explain the relationship between the friction coefficient and a dimensionless parameter for lubrication condition. The friction property has an effect on the size of surface texture on reduction friction, not only because of the density of dimple, but also because of the ratio of diameter/pitch. A ratio of approximately 0.5 is recommended under the tested friction condition. It is suggested that the ratio of d/p is an important parameter for surface texture design.

Trihexyltetradecylphosphonium bis(2-ethylhexyl)phosphate (phosphonium phosphate) ionic liquid is soluble in non-polar lubricants. It has been proposed as an effective anti-wear additive comparable to zinc dialkyldithiophosphate. Previously, phosphonium phosphate has shown a better anti-wear performance under some conditions such as high temperature. In this work, the tribological performance and the lubrication mechanism of phosphonium phosphate are compared with that of zinc dialkyldithiophosphate when lubricating silicon under various tribological conditions. This can lead to an understanding of the reasons behind the superior anti-wear performance of phosphonium phosphate under some conditions. A micro-scale study is conducted using a nanotribometer. The results show that both additives lead to a considerable reduction in both friction and wear coefficients. The reduction in the wear coefficient is mainly controlled by the formation of the tribofilm on the rubbing surfaces. Zinc dialkyldithiophosphate can create a thicker tribofilm, which results in a better anti-wear performance. However, the formation of a thicker film will lead to a faster depletion and thus phosphonium phosphate can provide better anti-wear performance when the depletion of zinc dialkyldithiophosphate starts.
