Abstract: A component having a layer system situated on the component is described, for increasing the resistance to wear of the component. The layer system in this context includes a phosphate layer and particles of solid lubricants, the layer system being free of any binding agent. A method for producing such a component is also described.

Abstract: A high-pressure pump having a rotationally driven drive shaft with a shaft portion embodied eccentrically to its axis of rotation, on which shaft portion a ring is rotatably supported. At least one pump element, has a pump piston, driven at least indirectly in a reciprocating motion by the drive shaft via the ring and resting at least indirectly on the ring. The ring is provided, at least on its outer face facing away from the shaft portion, with a coating of a friction-reducing paint in at least one region, in which the at least one pump piston rests at least indirectly on the ring.

Abstract: A high-pressure pump having a drive shaft and at least one pump element including a pump piston driven in a reciprocating motion by the drive shaft. A ring on which the pump piston is braced via a support element is rotatably supported on a portion of the drive shaft that is disposed eccentrically to its pivot axis. The ring and/or the support element, at least in their contact region, has many microscopic indentations, and a solid lubricant film is applied to the ring and/or to the support element, at least in their contact region.
