摘要: To provide a substrate consisting of carbon or non-metallic materials containing carbon with a layer of a metal having a high melting point, first an undercoat layer is applied to the substrate by plasma spraying in an inert atmosphere. The undercoat layer predominantly consists of rhenium, molybdenum, zirconium, titan, chrome, niobium, tantalum, hafnium, vanadium, platinum, rhodium or iridium. Onto that undercoat layer, a covering layer can be applied, by plasma spraying as well. In order to reduce the thermo-mechanical stress and to improve the adhesion of the undercoat layer on the surface of the substrate, the substrate is preheated prior to applying the undercoat layer. By means of such a method, carbon-containing substrates can be provided with an undercoat layer and, if required, with a covering layer quickly and reliably at low costs.

摘要: An implant is provided with a main body (1) and with a double coating applied to at least one surface section of the main body (1), wherein the double coating comprises an adhesion promoter layer (2), applied directly to the at least one surface section of the main body, and of an osteointegrative layer (3) covering the adhesion promoter layer (2). The layers (2;3) consist of pure titanium, wherein the adhesion promoter layer (2) has a thickness of 2-6 μm, in particular a thickness of 3-5 μm, and the osteointegrative layer (3) has a thickness of 50-70 μm, in particular of 55-65 μm. Moreover, the osteointegrative layer (3) has a porosity of 70-90% and a roughness Rz of at least 45 μm. A related method is also provided for producing such an implant.
