Abstract

304,396. Dicker, S. G. S., (Naamlooze Vennootschap Philips' Gloeilampenfabrieken). Oct. 31, 1927. Vacuum tubes.-In a process for coating metallic or non-metallic bodies with one or more of the metals rhodium, iridium and ruthenium, the bodies are heated in an atmosphere containing one or more volatile compounds of the metal or metals, e.g., the carbonyl halogen compounds such as the carbonyl chlorides. The body to be coated is introduced into a vessel containing the coating compound and the vessel is exhausted. The vessel is then heated to about 100‹ C. and the body itself to about 500‹ C. When compounds of more than one of the metals are used, the coating consists of an alloy of the metals the compounds of which are used. Bodies coated with these metals may be used as the starting material for the manufacture of incandescent cathodes which superficially contain electron active material such as an alkaline earth oxide.
