| Outline of Final Research Achievements |
In this study, to obtain nanocrystalline diamond films and to achieve good adhesion, diamond films were deposited on stainless steel substrate surface and surgical scalpel 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 stainless steel substrate surface by flame combustion. And, the films were synthesized on surgical scalpel 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 prevented.

近年，医療界では切除術の手術用メスの需要が増加している．しかしながら，切除術の手術用メスは使用している間に摩耗し，さらには様々な荷重が掛かることで，手術用メスの破損が問題となっている．このことから，その都度，手術用メス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切除術の手術用メス材料であるステンレス鋼基板上ならび手術用メス上に高硬度，耐摩耗性，耐久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，手術用メスの摩耗や破損の抑制により長寿命につながると考えられ，手術用メスへの新たな皮膜技術につながるものと期待される．
