Summary:	Title screen The effect of ion irradiation on the strength characteristics of magnesium oxide and ceramics based on zirconia is studied. The MgO samples were a single crystal grown in an artificial manner. Samples of zirconium ceramics were prepared by ceramic technology. Irradiation of MgO crystals was carried out by Si{+} ions (E=150 keV), Fe{+} (E=70 keV), C{+} (E=50 keV) at room temperature. The fluence varied within the range (10{16}-10{17}) сm{-2}. The modification of the investigated types of ceramics was carried out by ions Al+ (Е=60 keV), Ar{+} (Е=60 keV), N{+} (E=50 keV). We used ion beams of microsecond duration and moderate power (the current density in the pulse was 3 10-{3 }A/cm{2}). Fluence was 10{17} cm{-2}. The irradiation of the ceramics with an ion beam C{+} (E=50 keV) was also performed with nanosecond duration ([tau]=50 ns). It is established that ionic irradiation of magnesium oxide leads to an increase in crack resistance and a critical stress intensity factor. Irradiation of ceramics leads to hardening of its near-surface layers. Режим доступа: по договору с организацией-держателем ресурса
