Abstract: A stimulation electrode has an electrode surface at least partially covered with a coating of titanium nitride, the titanium nitride having on its side remote from the electrode surface a larger surface than the region of the electrode surface covered by the titanium nitride. The titanium nitride is covered with at least one oxidation protection layer on its surface remote from the electrode surface. The stimulation electrode is useful, for example, in cardiac pacemakers, neuro-stimulation devices and other human implants.

Abstract: The present invention provides improved cathodes and industrialized methods for producing such cathodes using an industrial dosing valve-based electrode coating fluid emitting technique. The family of cathodes according to the present invention can be produced so that they inhabit a pre-existing metallic surface such as an inner surface of a titanium casing adjacent but insulated from direct electrical communication from an anode. Foil-type valve metal anodes as well as porous valve metal anodes formed from metallic powders may be used in conjunction with the cathodes of the present invention.

Abstract: A method is provided for producing electrode structures which have a supply line and a contact surface connected thereto, wherein a planar electrode material is roll bonded onto a planar carrier material and the thickness of the electrode material and carrier material is reduced by rolling. The electrode material is then structured with formation of contact surfaces and supply lines in its surface, and predefined parts of the electrode material are removed. Then, electrode material located on the carrier material is coated with a sealing compound or a foil, and the carrier material is then removed. The structure may be used in medical implants for neuro stimulation and/or muscular stimulation, for example in a cochlear implant, a retina implant, or a cortical electrode.

Abstract: A process for producing a coating on a refractory structural member, in which a noble metal alloy is applied as a coating material to the refractory structural member. The noble metal alloy contains, among other constituents, an oxidizable substance, which includes boron and/or phosphorus and/or antimony and/or arsenic. The refractory structural member and the coating are heated at least once in an oxygen-containing atmosphere to a temperature T that is greater than or equal to the liquidus temperature TL of the noble metal alloy. The oxidizable substance is oxidized during this heating process, and the oxide that has formed is at least partially vaporized. The temperature T is maintained until the proportion of oxidizable substance in the coating is <0.1 atomic percent, and the coated refractory structural member is then cooled.

Abstract: The invention relates to a metal component for discharge lamps, having a support of niobium or tantalum or of alloys based on niobium and/or tantalum, as well as a discharge lamp. The present invention is addressed to the problem of increasing the resistance to oxidation and corrosion of metal components having a support of niobium or tantalum or of alloys based on niobium and/or tantalum which are disposed in or on discharge lamps. The problem is solved according to the invention in that the support has a coating of one or more single layers which is formed of at least one noble metal and/or from a noble metal alloy.

Abstract: A support structure is provided for holding open lumina, the support structure having a stainless steel substrate and a platinum layer forming the surface of the structure. The structure has at least one gold layer arranged between the substrate and the platinum layer. The platinum layer is preferably applied with a pulsed current with current reversal, in order to avoid or reduce brittleness occurring by absorption of hydrogen during galvanic deposition of platinum. Such a support structure (stent) substantially withstands the high mechanical stresses, particularly bending and torsional forces that occur during application, without the formation of significant tears in the platinum layer.
