Sintering Conditions

The work demonstrated the sintering of zirconium dioxide ceramics by means of an electron beam produced by a plasma-cathode e-beam source operating at fore-vacuum pressure. The sintered ceramics consist of tetragonal-modified zirconium dioxide with grain size from 0.7 to 10 micrometers, depending on the sintering conditions. At constant sintering temperature, the density of the material and its grain size depend on the integrated energy injected into the sintered material by the electron beam.

Abstract We report here the results of our studies on the effect of injection of low-energy thermionic electrons on the suppression of instabilities of the beam-plasma discharge type in a beam-plasma during the transport of a powerful continuous electron beam generated by a plasma-cathode electron source in the forevacuum range of pressure. As result of thermionic electron injection, the plasma electron temperature decreased to 0.3 eV and the plasma density decreased by an order of magnitude to 10^15 m-3. The minimal thermoelectron current required for suppressing the beam-plasma discharge increases with increasing emission current and decreases with increase of the beam accelerating voltage.
