Influence of Contact Pressure on Central and Minimum Film Thickness Within Ultrathin Film Lubricated Contacts
Original language description
Recent numerical results have indicated that the relationship between the film thickness and the speed may not always follow the simple power law, especially under severe conditions. This paper is aimed at obtaining experimental results at high contact stresses and low speeds to study the thin film behavior. Ultra-thin lubricant films were observed at maximum Hertz pressures of 0.52, 1.01 and 1.54 GPa by using an optical test rig. Central and minimum film thickness values were obtained with thin film coolorimetric interferometry from chromatic interferograms. The non-linear behavior of both central and minimum film thicknesses in log-log coordinates was observed as rolling speed and thereby film thickness decreased. This tendency became more obvious athigher contact pressures.

Vliv kontantního tlaku na centrální a minimální tloušťku mazacího filmu u velmi tenkých mazacích filmů
Czech description
Článek shrnuje výsledky získané při studiu velmi tenkých mazacích filmů za vysokých kontaktních tlaků. Tloušťka mazacího filmu byla stanovována kolorimetrickou interferometrií pro hodnoty maximálního Hertzova tlaku 0.52, 1.01 and 1.54 GPa. Bylo zjištěno,že za těchto podmínek dochází k odchylce od lineární závislosti (v logaritmických souřadnicích) tloušťky mazacího filmu na rychlosti valení.
