Abstract: The invention relates to a sliding element, in particular a piston ring, having at least one running surface. The running surface comprises a coating, which from the inside to the outside has at least one first adhesive layer, a hard hydrogen-free DLC layer, a second adhesive layer, a soft hydrogen-containing, metal and/or metal carbide-containing DLC layer, which is softer than the hard hydrogen-free DLC layer, and a hard hydrogen-containing DLC layer, which is harder than the soft hydrogen-containing, metal and/or metal carbide containing DLC layer.
