The technology for producing high-fluidity molybdenum powder (86 sec) developed previously by the authors makes it possible using traditional methods of powder metallurgy, and in particular cold compaction in steel molds, to produce molybdenum compensators for semiconducting diodes. Rotary high-productivity equipment intended for compacting particularly small articles equipped with a system for individual metering of molybdenum to fill the die is developed and put into practice. A stepwise form for the punch working zone is suggested for obtaining the required outer radius of curvature. The efficiency of the rotary machine is at least 2400 articles per h with a maximum compaction force of 50 kN. |
