Effect of nanostructuring of Al-6%Mg aluminum alloy cathode on the glow gas-discharge current


The paper presents the results of studies on the effect of deformation nanostructuring of cathodes from aluminum alloy Al-6%Mg on the glow gas-discharge current in a discharge device. Microstructure and work function of nanostructured alloy are studied. It is shown that a decrease of the work function as a result of alloy nanostructuring leads to an increase of potential ion-induced electron emission yield and glow discharge current.
