Abstract
The flame combustion method enables the synthesis of diamond using acetylene-oxygen gas flame combustion in ambient atmosphere. It has various advantages over other methods. In this study, to obtain nanocrystalline diamond films and to achieve good adhesion, diamond films were synthesized by flame combustion using a mixture of commercial or high purity acetylene and oxygen gas with the addition of nitrogen gas. Nitrogen gas added as the nanocrystalline diamond promotion agent; nitrogen flow rate was varied. According to the results, at the mixture of commercial acetylene and oxygen gas, as nitrogen flow rate was increased, the diamond nanocrystallites was high density on the microcrystallites. At the mixture of high purity acetylene and oxygen gas, the optimal nitrogen flow rate was 0.500 cm3/s, and the diamond nanocrystallites was synthesized continuously on the diamond microcrystallites. They sowed very high density.
