Original abstract
Mineral oil formulated with PAMA was used to study the effect of very thin viscous boundary films on rough rolling sliding point contact behaviour. Film thickness evaluated from chromatic interferograms by thin film colorimetric interferometry was compared with values obtained with mineral base oil. The use of PAMA resulted in film thickness enhancement under very thin film conditions within both the smooth and rough concentrated contacts. It was observed that even very thin viscous boundary films can significantly reduce direct asperity interactions that was confirmed through the qualitative chromium layer wear test. Obtained results also suggest that thin viscous boundary films can provide some rubbing surface protection even un-der the operating conditions when thick viscous boundary films are not longer formed on rubbing surfaces.
