TRIBOLOGICAL SYSTEM WITH REDUCED COUNTER BODY WEAR

摘要

The invention relates to a tribological system with a substantially improved tribological behavior, said system at least partly covering a body with a first contact surface by means of a first coating and a counter body with a second contact surface by means of a second coating and comprising lubricant as an intermediate agent. The invention is characterized in that the first and the second coating each has a layer as the outermost layer. The composition of the outermost layer of the first coating and the composition of the outermost layer of the second coating are selected such that • both outermost layers lubricate steel surfaces upon being exposed to steel so as to make tribological contact, and • both outermost layers are materially related layers such that the element composition of the first outermost layer and the element composition of the second outermost layer match by at least 60 at.%.
