| Summary: | Title screen Modification of the structural phase state of the surface layer of zirconium ceramics irradiated byhighpower pulsed beams of carbon ions at a pulse energy density of 3 J/cm2 is revealed using Xray phaseanalysis and scanning electron microscopy. The analysis of roentgenograms indicates efficient formation ofthe hightemperature cubic modification of zirconium dioxide. The study of the depth distribution of oxygenions using the secondary ion mass spectroscopy yields deficit of oxygen in the surface layer of the irradiatedceramics. A violation of the oxygen stoichiometry leads to a significant (by several orders of magnitude)increase in the conductivity of the samples under study. Mechanical characteristics (microhardness, nanohardness, and Young modulus) of the zirconium ceramics are determined after processing with highpowerpulsed beams.
