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." . "Influence of Contact Pressure on Central and Minimum Film Thickness Within Ultrathin Film Lubricated Contacts"@en . "127" . .
