Description
спирта и последующего нагрева гранулированной смеси по режиму, определ емому областью, ограниченной пр мыми ть Т2,alcohol and subsequent heating of the granulated mixture according to the mode defined by the area bounded by the straight line T2,
ts и Т4.ts and t4.
Прессование контактов провод т на гидравлическом прессе при давлении 4 т/см. Спекают контакты в атмосфере азота особой чистоты при 850°С в течение I ч, после чего контакты допрсссовывают при давлении 8 т/см и отжигают в атмосфере азота особой чистоты при 450°С в течение 0,5 ч. В таблице представлены результаты проведенного исследовани вли ни способа получени никелевого порошка дл подсло электрических контактов на состо ние (по сцеплению частиц между собой) порошка, концентрацию углерода в порошке и структуру контактов.The contacts are pressed on a hydraulic press at a pressure of 4 t / cm. The contacts are sintered in a nitrogen atmosphere of high purity at 850 ° C for I h, after which the contacts are doped at a pressure of 8 t / cm and annealed in a nitrogen atmosphere of high purity at 450 ° C for 0.5 h. The table shows the results of the study. the influence of the method of producing nickel powder for the sublayer of electrical contacts on the state (on the adhesion of the particles to each other) of the powder, the carbon concentration in the powder, and the structure of the contacts.
