摘要：

The specific erosion rates of cathodes from Zr and ZrB(2) used in the water-stabilized plasma gun PAL 50 were measured. Very good values were obtained for ZrB(2) establishing this material as one of the best prospects for such cathodes. X-ray microanalysis of the cross section proved that the emitting surface of ZrB(2) contained zirconium oxide.
