To this element, the sphere of lubrication has been conceptualized utilizing numerous noncontiguous modes of operation ― boundary, fluid-film, and dry and good lubrication. Engineers and analysts have lengthy needed to take care of previous proof that many tribological units, equivalent to flat floor and centrally pivoted sliders, can act as potential bearings ― contradicting simple hydrodynamic concept.
Tribology of Interface Layers introduces a brand new suggestion in which disparate modes are proven to truly be specific levels of a tribological continuum spanning a big selection of fabric lubricants. the writer information those phenomena and offers a singular definition of lubricants as intermediate layers.
Explores the phenomenon of continuum spectrum as utilized to new powder lubrication technology
The e-book illustrates that opposite to earlier knowing, some of the lubrication modes ― from dry to hydrodynamic to powder lubrication ― all overlap one another inside a tribological spectral continuum. It additionally elucidates the truth that bearings, seals, dampers, and comparable units utilizing submicron powder lubricants own quasi-hydrodynamic features such as traditional fluid movies. equally, powder movies own quasi-hydrodynamic good points that let them to behave as traditional fluid movie bearings. the sector of tribology has characteristically been offered by way of disparate regimes, yet this technique of type lacked adequate rigor. This quantity explains that characterization and remedy of anyone regime might require the simultaneous accounting of numerous varied modalities which are found in a specific mode of operation. in line with experimental and theoretical paintings, this article exhibits how the interdependence of powder and hydrodynamic lubrication exemplifies that perpetuity in tribological processes.
writer Hooshang Heshmat used to be available for a e-book signing on the 2010 STLE Meeting.
Dr. Heshmat was once the 2007 recipient of the Mayo D. Hersey Award, bestowed on someone in popularity of unique and non-stop contributions over a considerable time period to the development of the technology and engineering of tribology.
