However, when considering asperities as contraformal Hertzian contacts, elastic deformation may allow for the existence of thin micro-elastohydrodynamic lubricant films preventing direct solid body contact even at speeds which otherwise would be regarded as deep within the mixed lubrication regime close to boundary lubrication. These films may not be able to prevent wear completely, but may reduce friction significantly in comparison to dry friction Preprints Presented at the Asle Annual Meeting, 1984 Preprints Presented at the Asle Annual.

Also, for the same applied load the coefficient of friction increases with increase in elastic deformation.

An engine in a Chevy pickup truck might metamorph from running just fine to not running, with the crankshaft held fast by unseen forces. Lack of oil might have caused local temperatures so high the various rod or main bearing inserts became welded to the crankshaft. If removed they might look similar to page 15/20 here pdf.

Then the focus shifts towards discussing in more detail the existing semi-analytical methodologies developed in recent times to model the micro-elastohydrodynamic lubrication problem Mitigation of Hydrodynamic Resistance: Methods to Reduce Hydrodynamic Drag read for free. Viscous materials (liquids) resist fast deformation under the load. In contrast to an elastic material, which returns to its original shape immediately after the load is removed, a viscous material flows changing its dimensions for some time after changing the load (time dependent process). Viscoelasticity of polymers plays an important role in their tribological behavior , e.g. Tribology and Biophysics of Artificial Joints, Volume 50 (Tribology and Interface Engineering) http://old.gorvestnik.ru/library/tribology-and-biophysics-of-artificial-joints-volume-50-tribology-and-interface-engineering. The enhanced tribological properties of these abrasive tools were believed to stem from the formation of a self-lubricating layer that constituted by sulfide film and carbon deposited film, which had significant influence on the phenolic resin transfer process from substrate to the counter steel surface, and also had functions of anti-friction, anti-wear, and an improvement of surface quality online. In other applications it is often desirable to minimize friction losses to improve efficiency, though sometimes high friction is desired to prevent sliding and wear ref.: ENGINEERING TRIBOLOGY britwayz.org. To make clear the relation between fatigue life and influential factor, fatigue tests of rolling bearings are conducting with common theme.
