WERKWIJZE VOOR DE VERVAARDIGING VAN ROOSTERELEKTRODEN VOOR ELEKTRISCHE ONTLADINGSVATEN.

摘要

A grid electrode for an electronic discharge vessel wherein the wire which forms the grid is first covered with a layer of an intermetallic compound comprising a high-melting metal such as zirconium or titanium and a metal of Group VIII of the Periodic System, for example platinum. The intermetallic compound is applied to the grid wire in powdered form and then sintered after which an outer layer of a noble metal, for example platinum is then applied electrolytically.
