Abstract :
The influence of electrovacuum devices anode treatment by prehydrogen firing and nitric acid heckling has been investigated. St was determined that anode metric acid heckling leads to decrease of power take-oft at the initial stage 5-vold, shortage of pre-burning time 2-2,5 fold and increase of anode current density 40-45 per cent.
