| Research Abstract |
In order to develop carbon nitride biomaterial hard coating by ion beam mixing method, We investigated the subject under the following three heads : (l)synthesis of carbon nitride films on by ion beam mixing method ; (2)microstructure and tribological properties of carbon nitride films ; and (3) possibility of application for biomaterial hard coatings.
The following results were obtained :
1. We clarified that the formation condition of C-N thin film on silicon and titanium substrate by ion beam mixing method, in which carbon was evaporated by electron beam and nitrogen ions were simultaneously bombarded.
2. We clarified that C-N films were consisted of C-N network like the disordered turbostratic structure.
3. We clarified that the hardness was up to 20 GPa and the frictional coefficient was 0.2.
4. We concluded that the mechanical properties and the tribological properties of C-N film were suitable for biomaterial.
