New PDF release: Tribology of Interface Layers

By Hooshang Heshmat

To this aspect, 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 practicable bearings — contradicting simple hydrodynamic thought.



Tribology of Interface Layers introduces a brand new proposal in which disparate modes are proven to really be specific levels of a tribological continuum spanning a wide range of fabric lubricants. the writer information those phenomena and provides a unique 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 realizing, many of the lubrication modes — from dry to hydrodynamic to powder lubrication — all overlap one another inside of a tribological spectral continuum. It additionally elucidates the truth that bearings, seals, dampers, and comparable units utilizing submicron powder lubricants own quasi-hydrodynamic features reminiscent of traditional fluid motion pictures. equally, powder motion pictures own quasi-hydrodynamic beneficial properties that allow them to behave as traditional fluid movie bearings. the sphere of tribology has regularly been provided when it comes to disparate regimes, yet this technique of type lacked enough rigor. This quantity explains that characterization and therapy of anybody regime may well require the simultaneous accounting of a number of varied modalities which are found in a specific mode of operation. in keeping with experimental and theoretical paintings, this article indicates how the interdependence of powder and hydrodynamic lubrication exemplifies that perpetuity in tribological processes.

Author Hooshang Heshmat was once to be had for a ebook signing on the 2010 STLE Meeting.

Dr. Heshmat was once the 2007 recipient of the Mayo D. Hersey Award, bestowed on somebody in reputation of exceptional and non-stop contributions over a considerable time period to the development of the technological know-how and engineering of tribology.
