Research Abstract

A diamond film was formed on a WC-Co microdrill with a three-dimensional complex shape by a hot-filament assisted chemical vapor deposition technique using methane and hydrogen. Prior to diamond deposition, the microdrill was dipped into nitric acid and then ultrasonically pretreated using nanoscale diamond particles suspended in water. These pretreatment were effective to improve the adhesion property of diamond film and to enhance the deposition density Diamond deposition was carried out through two steps : the first methane concentration was kept at ca. 6% in hydrogen and the second one was maintained at ca. 1% in hydrogen. The first step was important to form a continuous well-adhering diamond thin film. A diamond-coated microdrill was tested to bore holes through a machinable glass ceramics, and as a result, its boring performance was found to be about 7 times higher than that of uncoated one.
