Title :
Brazing of molybdenum and tungsten
Abstract :
A method is described of brazing molybdenum and tungsten parts of a magnetron cathode which operates at high temperatures. The brazing medium is ruthenium powder or mixtures of ruthenium and molybdenum powders. Evidence of a eutectic, melting at about 1900°C was obtained. In production, an atmosphere of forming gas is used with a blazing temperature of 2100°C (optical).
