Experimental Study of the Interfacial Slip on Hydrodynamic Lubrication Under Different Wettabilities

ABSTRACT This article presents an experimental study about boundary slippage on the film thickness of hydrodynamic lubrication (HL) using a custom‐made slider‐on‐disc bearing testing apparatus. The interfaces with different affinity were obtained by surface energy modification of sliders with variou...
