Thin film colorimetric interferometry was applied to the preliminary study of boundarylayers formation for a several liquids of known molecular structure that have been previously stud-ied by the force balance method. This technique intended for the study of very thin lubrication filmsdown to a few nanometers in a point contact between a steel ball and a transparent disk combinespowerful film thickness mapping capabilities with high accuracy. Central and minimum film thick-ness 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 obtainedfrom surface force apparatus measurements. OMCTS and n-tetradecane were found to formboundary films that result in a considerable enhancement in film thickness at slow speeds.
