Abstract

For friction reduction in sliding bearing, it is known to structure the sliding surface (1) by ECM by introducing a plurality of microscopic small indentations (27). According to the invention it is proposed in particular in the same process step to smoothen also the intermediary spaces (6) between the indentations (27), thus to remove the tips of the surface profile.
