Abstract

Cleaved {100} MgO single crystal surfaces have been implanted with 300keV Ti+and Cr+ ions to doses in the range 10 16 −1018 ions cm−2. Localised plasticity and fracture behaviour has been investigated using microhardness indentation tests at loads of between 10gf and 500gf.Significant surface hardening has been observed at lower doses with amorphisation related softening occurring at higher doses. Post-implantation heat treatments produce precipitation reactions with associated hardness changes.
