Metal component and discharge lamp

摘要

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.
