METHOD OF PRODUCING PRESSED METAL-ALLOY PALLADIUM-BARIUM CATHODE Russian patent published in 2017 - IPC C22C5/04 C22C1/04 B22F3/16 H01J1/14 H01J9/04

Abstract RU 2627707 C1

FIELD: metallurgy.

SUBSTANCE: intermetallide Pd5Ba is produced by melting, is ground in an atmosphere of inert gas or CO₂ to obtain a powder, the resulting powder is mixed with palladium powder and mechanically activated by the planetary or vibrator mill for 5-15 minutes. The powder obtained after mechanoactivation is compressed, and the compact is sintered in an argon atmosphere in a beam of fast electrons at a temperature of (700-800)°C for 25-40 minutes.

EFFECT: increasing the coefficient of secondary electron emission of the pressed metal-alloy cathodes Pd-Ba.
