METHOD OF PRODUCING BORIDED DISPENSER CATHODE |
摘要 |
A borided dispenser cathode of the type including a metallic base material is made by cleaning the cathode by annealing it in a hydrogen-containing atmosphere, depositing boron on the cathode by heating the cathode in an atmosphere containing a gaseous boron compound, and forming a boride of the metallic base material by heating the cathode to its operating temperature in a non-reactive atmosphere and maintaining the temperature for a time period sufficient to enable deposited boron to combine with the metallic base material. |
