Experimental Study of Lubricant Film Thickness Behavior in the Vicinity of Real Asperities Passing through Lubricated Contact
Jul 01, 2004; ... This article presents an experimental study of the influence of real surface micro-geometry on the film thickness in a circular elastohydrodynamic (EHD) contact formed between a real, random, rough surface of steel ball and smooth glass disk. Phase shifting interferometry was used to measure in ...
A Routine High-Pressure Viscometer for Accurate Measurements to 1 GPa
Jul 01, 2004; ... Of the fields for which the piezoviscous property of liquids is of interest, elastohydrodynamics is unique in deriving its existence from this property. Even recent publications in the field, however, have based the description of the pressure variation of viscosity on myths rather than ...
Transmission Electron Microscopy of Boundary-Lubricated Bearing Surfaces. Part I: Mineral Oil Lubricant
Jul 01, 2004; ... Transmission electron microscopy (TEM) was performed on the near-surface material (depth <500 nm) of tapered roller bearing inner rings (cones) that were tested at two levels of boundary-lubricated conditions in mineral oil with no additives. Site-specific thinning of cross section cone ...
"Evolution of Wear in a Two-Dimensional Bushing"
Jul 01, 2004; ... Discussion by Stephen Boedo, Rochester Institute of Technology, Department of Mechanical Engineering, Rochester, NY of "Evolution of Wear in a Two-Dimensional Bushing" by Daniel J. Dickrell, III and W. Gregory Sawyer, Tribology Transactions, 47(2), pp ....
X-Ray Photoelectron Spectroscopy Analysis of Antiwear Tribofilms Produced on Boundary-Lubricated Steel Surfaces from Sulfur- and Phosphorus-Containing Additives and Metal Deactivator Additive
Jul 01, 2004; ... X-ray photoelectron spectroscopy (XPS) was performed on AISI 52100 steel surfaces subjected to sliding in the boundary lubrication regime at 32 and 100°C. The specimens were lubricated with base oil blended with individual additives containing sulfur (S), phosphorus (P), or metal deactivator, as ...
A Divide-and-Conquer Parallel Computing Scheme for the Optimization Analysis of Tribological Systems
Jul 01, 2004; ... The trend of using commercial products and open source packages to construct a scalable computer cluster for distributed computing to minimize the execution time of numerical optimization has long been expected. However, in the tribology field progress has been slow due to the complexity of ...
