Coating is one of the processes used to improve the tribological properties of surfaces. In this article, the increase in useful lifetime of soft-coated part and the validity of Miner’s rule for predicting adhesive wear are investigated. In order to achieve this aim, a series of pin-on-disk experiments on three sets of disks were performed by single-force, two consecutive-forces and three-forces loading conditions, at two constant speed levels. These experiments were performed for simple, double-layer and four-layer coated disks. As a result, the validity of Miner’s rule for consecutive loads at a constant speed is shown. Also, the work done by friction force and wasted energy are investigated. It is shown that for each of the parts with a specified coating, regardless of loading sequence, the work done by friction force up to the failure point is almost a constant value.
