Description
леиным (в течение 0,5 ч) подъемом температуры до 150-200°С. После этого смесь запрессовывают в керн катода при удельном давлении 15 т/см и спекают при 1750°С в атмосфе ре водорода в,течение 1 мин.Lein (within 0.5 h) by raising the temperature to 150-200 ° C. After that, the mixture is pressed into the core of the cathode at a specific pressure of 15 t / cm and is sintered at 1750 ° C in a hydrogen atmosphere for 1 minute.
Катод, изготовленный по предлагаемому способу, работает без падени тока более 3000 ч при рабочей температуре катода 1120°С и истинной плотности отбираемого тока на уровне 2,0 А/см.The cathode manufactured by the proposed method works without a current drop of more than 3000 hours at a cathode operating temperature of 1120 ° C and a true current density of 2.0 A / cm.
У прессованного катода, изготовленного известным способом, в тех же услови х работы уже через 200-250 ч срока службы имеет место падение тока 15-20%.In an extruded cathode manufactured in a known manner, under the same operating conditions, after 200-250 hours of service life, a current drop of 15-20% occurs.
Таким образом, в результате использовани предлагаемого способа эксплуатационные характеристики прессованного металлопористого катода удаетс довести до уровн пропитанного металлопористого катода.Thus, as a result of using the proposed method, the performance characteristics of a molded metal-porous cathode can be brought to the level of the impregnated metal-porous cathode.
