A bearing system having a bearing pair made up of at least one bearing and at least one running partner, wherein a coating which is made up of a layer of which the main constituent is amorphous SiOis applied to at least one running surface of the bearing pair.

Bearing system

A process for the application of layers composed of ceramic or organoceramic materials on surfaces of metals, semimetals or compounds thereof and also components or assemblies made of these materials by a chemical deposition process from the gas phase at atmospheric pressure or 30% below this and process temperatures during deposition below 500&#xb0; C. The deposition process is carried out in one operation, wherein the reactive chemical substances and the precursors are homogeneously backmixed in the common gas space, and the average residence time as a ratio of volume of the gas space to gas throughput is matched to the rate-determining step of the catalyzed gas-phase reaction of the coating process so as to achieve a deposition rate of from 10 to 2000 nm per hour.
