Titanium containing carbonaceous thin films have been examined for some time because of their tribological properties@footnote 1-4@ and because of the prospect of their biomedical applications.@footnote 5,6@ Composite Ti/CH films reveal hardness Hv up to 35 GPa and coeficient of friction below 0.3 for Ti concentrations below 40 at % The presence of Ti in C:H matrix causes cellular reactions of bone marrow cells. Therefore Ti/C:H hard coating can be applied for bone implants. Composite Ti/CH films were deposited using an unbalanced dc planar magnetron equiped with Ti target operating in Ar/n-hexane or Ar/methane mixtures. Deposition process is described in relation to composition and structure as well as basic electrical, optical properties and hardness of the films. XPS analysis of the film surface revealed considerable oxidation and static contact angle of a water droplet ranged from 68 to 85 deg. The potential application of these films for bone implants has been assessed. @FootnoteText@ @footnote 1@ N.E. LoBiondo, R. R. Aharonov, R. P.
