| 20090127226 | PROCESS FOR PRODUCING SELF-SUPPORTING TITANIUM AND NICKEL LAYERS - A process for producing a self-supporting layer made of a titanium and nickel alloy with superelastic and/or shape memory properties has the following steps: a substrate entirely or at least mainly made of silicon is provided, a layer of said alloy is applied to a surface of the substrate, the substrate with the desired form is cut out of a wafer or formed by a wafer with the desired form; at least some zones of the lateral surfaces of the substrate adjoining the zones of the surface of the substrate which receive the layer are subjected to an etching process; a layer of said alloy is applied to the surface of the substrate; and the substrate is removed from the applied layer. Also disclosed is a substrate suitable for carrying out the process and an object, in particular an implant, comprising at least one layer produced by this process. | 05-21-2009 |
