| 330 | _aThe patterns of depth microhardness, nanohardness and modulus of elasticity of alumina ceramics were investigated by microindentation and nanoindentation methods after treatment with a beam of ions of the composition: carbon ions (C+, Cn+) and protons (H+) in a ratio of 85%/15%. The accelerating voltage was 180 keV. The experiments were performed at pulse energy density (W) of 0.3, 1 and 1.5 J/cm2. It is shown that ion treatment increases the strength of the surface layers of ceramics at depth that exceeds the penetration depth of accelerated ions by an order of magnitude or more. That is, there is a long-range effect characteristic of the ion treatment of metals and alloys. The analysis of the processes of energy release and structural changes in the surface layers shows that melting and recrystallization of the thin surface layer of ceramics observed in ion treatment are not the determining factors that change the strength properties of ceramics under these layers. It is shown that hardening of these layers occurs by the shock-wave mechanism initiated by local overheating of the surface layers of ceramics by intense pulsed ion beam. | ||
