High Pressure Rheology of Lubricants (Part 6)
Tribology OnlineIn the extended Dowson-Higginson density equation in the second report, it was found that the reciprocal of the density increase ratio, 1/(ρpt/ρ0t−1), is proportional to the reciprocal of the pressure temperature, 1/PT.

Vacuum tribological behaviour of self lubricant quasicrystalline composite coatings [PDF]
, 2003 High temperature resistant self-lubricant coatings are needed in space vehicles for components that operate at high temperatures and/or under vacuum. Thick composite lubricant coatings containing quasicrystalline alloys (QC) as the hard phase for wear ...

High Pressure Rheology of Lubricants (Part 2)
Tribology OnlineIn elastohydrodynamic lubrication (EHL) theory published in 1962, Dowson et al. derived a density pressure relational equation. Therefore, it seemed that this equation could be utilized as an estimation equation of the density term of the viscosity ...

Wear Tests of a Potential Biolubricant for Orthopedic Biopolymers [PDF]
, 2015 Most wear testing of orthopedic implant materials is undertaken with dilute bovine serum used as the lubricant. However, dilute bovine serum is different to the synovial fluid in which natural and artificial joints must operate. As part of a search for a

Three-dimensional boundary element and experimental analysis of lubricant ceramic surface ring cracks in rolling contact. [PDF]
Surface defects such as ring cracks are located on silicon nitride ceramic rolling elements.The random nature of ring crack position creates difficulties in predicting rolling contact fatigue (RCF) life.
