In this study, to obtain nanocrystalline diamond films and to achieve good adhesion, diamond films were synthesized on tungsten carbide surface by flame combustion. To obtain the bonding strength of synthesized films, the scratch test was performed, and the bonding strength was determined and discussed.The diamond nanocrystallites on the microcrystallites was synthesized on molybdenum substrate surface by flame combustion.The diamond nanocrystallites on the microcrystallites was synthesized on tungsten carbide substrate surface, too.The bonding strength of synthesized films was determined by the scratch test.The diamond crystallites and the bonding strength of synthesized films were affected by the synthesis conditions.
