Abstract
In a method for coating a sliding element, in particular a piston ring or a cylinder liner of an internal combustion engine, DLC phases are embedded into a hard material layer as said hard material layer is deposited. A sliding element, such as a piston ring or a cylinder liner of an internal combustion engine, comprises a hard material layer with embedded DLC phases.
