| Outline of Final Research Achievements |
In this study, to obtain nanocrystalline diamond films and to achieve good adhesion, diamond films were deposited on Co-Cr alloy surface and bone head for artificial hip joint by flame combustion. To obtain the bonding strength of synthesized films, the scratch test was performed. And, to observe the wear resistant of synthesized films, the wear resistant test was performed. The diamond films and the diamond nanocrystallites were synthesized on Co-Cr alloy substrate surface by flame combustion. The bonding strength of synthesized films was determined and discussed by the scratch test. And the wear resistant of synthesized films was discussed. The diamond nanocrystallites and the delaminatiom of synthesized films were affected by the synthesis conditions.
