Abstract


To reduce the negative influence of diamond wear debris during dry running of CVD diamond coated specimens, surface micro structures are generated into SiC sliding bearings. After diamond deposition the topography of the structured surface is well reproduced by the diamond coating. Creating micro valley and micro pore structures into diamond surfaces improves the sliding behaviour under dry running conditions considerably. Abrasive diamond debris accumulates initially at grain boundaries between worn diamond grains. With increasing wear of the mating diamond surfaces the generated debris particles accumulate in the micro valleys and micro pores. The benefit of surface micro structuring on dry sliding friction is exposed as soon as the cavities at diamond grain boundaries disappear completely due to wear and only surface micro structures remain for hiding wear debris.
