Claims (2)

1. Прессованный металлосплавный палладий-бариевый катод, представляющий собою матрицу Pd в виде ленты с распределенной в ней фазой интерметаллида Pd5Ba, отличающийся тем, что интерметаллид в ленте находится в ячейках, равномерно распределенных в матрице.1. A pressed metal-alloy palladium-barium cathode, which is a Pd matrix in the form of a tape with the Pd 5 Ba intermetallic phase distributed in it, characterized in that the intermetallic compound in the tape is in cells uniformly distributed in the matrix. 2. Способ получения прессованного металлосплавного палладий-бариевого катода, включающий получение методом плавки интерметаллида Pd5Ba, его размол в атмосфере инертных газов или СО2 и введение в матрицу палладия, отличающийся тем, что порошок интерметаллида Pd5Ba вводится следующим образом: на тонкую ленту Pd накладывается такая же лента со сформированными в ней ячейками (сквозными отверстиями), находящимися между собой на равных расстояниях, в ячейки засыпается порошок интерметаллида Pd5Ba и сверху помещается аналогичная нижней лента чистого палладия. Полученная конструкция прессуется под давлением 10-12 т/см2, после чего отжигается в течение 1-2 час в инертной атмосфере при температуре, 800-900°C, а далее осуществляется горячая прокатка до достижения лентой требуемой толщины.2. A method of producing a pressed metal-alloy palladium-barium cathode, including the preparation of a Pd 5 Ba intermetallide by melting, its grinding in an atmosphere of inert gases or CO 2, and introducing into the palladium matrix, characterized in that the Pd 5 Ba intermetallic powder is introduced as follows: Pd belt superimposed same ribbon with formed in it the cells (through holes) located between them at equal distances, is filled with the powder of the intermetallic Pd and Ba 5 is placed from above similar to the lower cleaning belt into cells of palladium. The resulting structure is pressed under a pressure of 10-12 t / cm 2 , after which it is annealed for 1-2 hours in an inert atmosphere at a temperature of 800-900 ° C, and then hot rolling is performed until the tape reaches the required thickness.
