Originální abstrakt
Thin film colorimetric interferometry was applied to the preliminary study of boundary layers formation for a several liquids of known molecular structure that have been previously studied by the force balance method. This technique intended for the study of very thin lubrication films down to a few nanometers in a point contact between a steel ball and a transparent disk combines powerful film thickness mapping capabilities with high accuracy. Central and minimum film thickness as well as film shape in the dependence on rolling speed was studied for hexadecane, oc-tamethylcyclotetrasiloxane (OMCTS) and n-tetradecane. Results are compared with data obtained from surface force apparatus measurements. OMCTS and n-tetradecane were found to form boundary films that result in a considerable enhancement in film thickness at slow speeds.
