COATING WITH ENHANCED SLIDING PROPERTIES

摘要

The present invention relates to coated sliding parts having coating systems which allow better sliding performance under dry and/or under lubricated conditions. The coating systems according to the present invention being characterized by having an outermost layer which - is a smooth oxide-containing layer in case of sliding applications under lubricated conditions, or - is a self-lubricated layer comprising molybdenum nitride, in case of sliding applications under dry or lubricated conditions. is a self-lubricated layer with a structured surface comprising a multitude of essentially circular recesses with diameters of several micrometers or below, the recesses randomly distributed over the surface.
