Measurement of Lubricant Film Thickness in a Slider-on-Disc Contact

In this paper, hydrodynamic lubrication behaviors of PAO (Polyalphaolefin) oils in a slider-on-disc conformal contact were measured with optical interferometry. The film thickness under different loads, speeds, oil viscosities and angles of inclination of slider were obtained. It was shown that unde...
