Method of manufacturing an electrode for a high-pressure gas discharge lamp and electrode for such a lamp

摘要

A thickened part (1) of a high-melting metal, which may contain emitter material, is formed on a carrier (2) of a high-melting metal. In order to manufacture such electrode structures in mass production and to obtain both various material transitions and combinations and optimum designs, the thickened part (1) is formed by reactive deposition from the gaseous phase (CVD method), preferably by laser-supported deposition from the gaseous phase.
