| Outline of Final Research Achievements |
In this study, to obtain nanocrystalline diamond films and to achieve good adhesion, diamond films were deposited on Ti substrate surface and dental implant by flame combustion. To obtain the bonding strength of synthesized films, the scratch test was performed. The microcrystalline diamond films and nanocrystalline diamond films were synthesized on Ti substrate surface by flame combustion. The bonding strength of synthesized films was discussed by the scratch test. The nanocrystalline diamond films and the delamination of synthesized films were affected by the synthesis conditions. The delamination of the nanocrystalline diamond films was completely prevented.

近年，医療界では歯科用インプラントの需要が増加している．しかしながら，歯科用インプラントは使用している間に腐食し，さらには様々な荷重が掛かることで，インプラントが破損してしまうことが問題となっている．このことから，インプラントを取り換えなければならないといった問題が発生する．本研究では，これらの問題を解決するため歯科インプラント用Ti基板上ならび歯科インプラント上に高硬度，耐摩耗性，耐腐食性に優れているナノ結晶ダイヤモンド皮膜の合成を行った．本研究で得られた成果は，インプラントの破損の抑制により長寿命につながると考えられ，インプラントへの新たな皮膜技術につながるものと期待される．
