DLC LAYER SYSTEM AND METHOD FOR PRODUCING SAID LAYER SYSTEM

摘要

Layer system consists of an adhesion layer, a transition layer and a covering layer arranged on a substrate. The adhesion layer comprises a 4, 5 or 6 sub-group element and silicon, the transition layer comprises a 4, 5 or 6 sub-group element and silicon and carbon, and the covering layer comprises carbon which is similar to diamond. The system has a hardness of at least 15, preferably 20 GPa, and an adhesion of at least 3 HF. Independent claims are also included for: (a) a process for the production of the layer system; and (b) a device for carrying out the process comprising a vacuum chamber (1) having a pump system (9) for producing a vacuum in the chamber, substrate holders (3), a gas supply unit (8) for process gas, a vaporizer (14), an electric arc production device (10, 13), a device for producing a substrate bias voltage, and magnetic field producing devices (17). Preferred Features: The layers are applied by plasma-supported vaporization.
