A process for the production of wear-resistant, coated surfaces includes the use of at least two electrodes connected to a voltages source which are mounted in, or border, a reaction space through which an electrolyte flows in which the surface to be coated is located. The process is distinguished by the fact that the direction of the flow of the electrolyte is selectively reversed at least once during the coating process to enable better control of the formation of the oxide layer.

Method and device for producing wear resisting surfaces

The invention relates to a hydraulic delivery device with a displacement unit which delivers a medium from a suction connection under output pressure to a pressure connection, connectable with a consumer, and under consumer pressure, and a regulating device for setting and/or limiting a volume flow delivered by the delivery device.
