By means of continuous friction and wear measurement, lubricated steel-steel and steel-aluminum contacts were evaluated. PHYSICAL REVIEW B 62, no. 20, 13667 - 13673. However, nanometer scale characterization of lubrication films offers a substantial challenge. The temperature varied directly with the inner ring speed. The definition of Tribology is: 'interacting surfaces in relative motion.' Machines consist of many component parts in contact with each other, such as bearings, gears, cams, tappets etc, which rub against each other in order to operate.

The mechanical engineer needs to acquire particular skills and knowledge. He/she needs to understand the forces and the thermal environment that a product, its parts, or its subsystems will encounter; to design them for functionality, aesthetics, and the ability to withstand the forces and the thermal environment they will be subjected to; and to determine the best way to manufacture them and ensure they will operate without failure download. The objective was to identify mechanisms explaining the experimentally observed lubricating properties of the two amorphous films.

Characterization of such films is necessary for developing optimized lubricating films. However, nanometer scale characterization of lubrication films offers a substantial challenge. Optical techniques such ellipsometers can be used for measuring lubrication thickness of large sections, (greater than 10 square micrometers), of a surface. Measurement of the localized (less than 1 micron) film thickness is not possible with the ellipsometer ref.: Mitigation of Hydrodynamic Resistance: Methods to Reduce Hydrodynamic Drag http://old.gorvestnik.ru/library/mitigation-of-hydrodynamic-resistance-methods-to-reduce-hydrodynamic-drag.

In this work, an attempt has been made to study the effect of particle size on wear behaviour of molybdenum coated steel. Two types of Mo coatings were deposited on American Iron and Steel Institute (AISI) 1020 steel substrate, one is with particle size of 15–40 µm (type I) and another one is with 40–90 µm (type II) using plasma spraying , source: Tribological Modeling for read epub http://britwayz.org/?library/tribological-modeling-for-mechanical-designers-astm-special-technical-publication-stp.
