Abstract
In a method for manufacturing a glow cathode for an electron tube, a layer of an alloy, such as iridium-lanthanum (Ir.sub.2 La), is produced on a substrate by coating the substrate, such as in a number of layers, with the components of the alloy by deposition from the vapor phase, such that the components of the alloy are present in the stoichiometrically correct ratio on the substrate, and in that the substrate is heated for a time duration adequate for alloy formation to a temperature that is lower than the melting temperature of the phase of the alloy having the lowest melting point.
