[DE] Die Erfindung bezieht sich auf eine verschleißfeste Beschichtung für ein Maschinenteil, das reibendem Verschleiß ausgesetzt ist mit einer kohlenstoffbasierten, Wasserstoff enthaltenden Funktionsschicht (4), die unterstrukturiert ist mit wenigstens einer nichtmetalldotierten Schicht.
[EN] The coating for a component such as a roller bearing, comprises a functional layer (4), which contains hydrogen and is based on amorphous carbon, an adhesive layer provided below the functional layer, and a supporting layer (3), which is made of metal-containing or non-metal-containing carbon layer containing hydrogen, provided below the functional layer. The functional layer has layers, which are doped with a non-metal, have no metal and no metal-doping and differentiate themselves in a characteristic influencing the crystallization. A further layer lies between the layers. The coating for a component such as a roller bearing, comprises a functional layer (4), which contains hydrogen and is based on amorphous carbon, an adhesive layer provided below the functional layer, and a supporting layer (3), which is made of metal-containing or non-metal-containing carbon layer containing hydrogen, provided below the functional layer. The functional layer has layers, which are doped with a non-metal, have no metal and no metal-doping and differentiate themselves in a characteristic influencing the crystallization. A further layer lies between the layers of the functional layer, is made of carbon with hydrogen and is undoped with non-metal. One of the layers is thinner than 20 nm. The characteristic, in which adjacent non-metal doped layers differentiate themselves, is the doping factor, the hydrogen portion, the portion of the sp3-hybridized atoms or kind of doping atoms. A non-metal doped layer in the functional layer is adjacent to a non-doped layer. Thirty layers doped with non-metal and undoped with non-metal are alternatively provided in the functional layer in an area-wise manner. One of the non-metal doped layers has gradients of the doping density vertical to a surface (64). The gradient is directed, so that the non-metal portion increases to the surface of the functional layer. The doping density has gradients over the thickness of the layer. One of the layers is thicker than 100 nm. The thickness of the functional layer is 0.5-10 mu m. Independent claims are included for: (1) a method for producing a coating; and (2) a roller bearing with a coating. |
