Abstract: A TiO layer was deposited onto carbon/carbon composite through Ion Beam En-hanced Deposition technique. Porous network was formed after the TiO layer was subjected to alkali treatment with high concentration, and the network of titanium oxide induced the deposi-tion of biological apatite in the simulated body fluid. So, biomimetic activation was realized for carbon/carbon composite.

Key words: carbon/carbon composite, biomimetic activation, biomaterial
