This article focuses on analyzing the correlation between the degree of starvation and friction under the sliding motion in a ball-disk machine. The objective of this study was to define approximately the degree of starvation in the contact based on measuring one parameter (the relative coefficient of friction). Such an approximate approach could be useful in cases of opaque contacts where the optical interferometry technique cannot be used; for example, a steel ball on ametal disk. Experimental measurements were conducted under different degrees of starvation using a tribometer equipped with a torque sensor and a high-speed digital camera. The results showed agreement between the theoretical equations and the experimental measurements. Thus, it can be stated that the approximate ratio of the film thickness reduction can be predicted based on accurate measurements of friction.
