Authors: Arzamasov V B , Smirnova E E , Stroev A A , Polunov I L , Rykov D E
Published: April 2022

The article considers experimental investigation of influence of tungsten alloying by transitive metals of IV A - VI A groups on its thermoemission properties. It is established that at temperatures of test 1500 and 2400 С almost monotonous reduction of electron work function of pure tungsten is observed after additing of the given alloying elements. It is shown that at a certain temperature on surface of the sample the layer of atoms of zirconium adsorbed from internal volumes is formed that essentially increases alloy thermoemission.
