Summary:Title screen
The influence of a high-current pulsed beam of low-energy electrons (HCBLE) on the structural state of near-surface layers of ZrO2(Y)-Al2O3 composite ceramic with various levels of porosity is studied using scanning electron microscopy (SEM). It is demonstrated that the electron processing leads to melting and subsequent crystallization of the ceramic near-surface layer with thickness of 30-40 μm. The surface microstructure and cross section of electron-beam-modified layers of ceramic specimens are analyzed using SEM. It is revealed that, in the irradiated near-surface layer of all considered ceramic types, there are actually no pores and grains of the corundum phase. It is found that electron beam irradiation leads to a decrease in grain size and formation of texture in the near-surface layers.
