This paper documents the effect of surface conditioning on the lifetime and the efficiency under typical loading conditions. The experimental work to determine the influence of the mechano-chemical surface treatment TCG on the number of cycles until mechanical damage of the contact surface and assessment of the rolling resistance in comparison to an untreated specimen is described in this paper. The surfaces of the specimen are evaluated by both optical and tactile surface measurements. The tests principle consists of the rolling of the cylindrical specimen between three loading discs, while one of them is driven by an electrical motor and at the same time, a loading force is acting upon it. Mechano-chemical surface treatments are a proven way to reduce friction and wear of components in sliding contact, especially under mixed lubrication conditions, but have so far not been considered for the optimization of the rolling resistance of bodies.
