Abstract The influence of ion implantation Ba + on the composition, structure and secondary emission properties of polycrystalline samples of Pd and Pd-Ba. It is shown that at low doses (D <10 15 cm -2 ) formed separate nanocluster phase, and at high doses (D ≥ 10 16 cm -2 ) - coarse sites Pd 2 Ba, Pd-Ba with sharp edges, the dimensions of which lie in the range 2 -10 microns. It has been established that ion-implanted samples exhibit relatively high emission efficiency than activated alloys.
