| Research Abstract |
This research work deals with reactive Laser sintering of boron carbide (B_4C) on a substrate from mixture of graphite and boron powder. The boron carbide (B_4C) is a hard material, therefore, it is expected to apply for polishing powder However, it is difficult to sinter, the material is not used sufficiently. It is expected to become adhesion between the boron carbide and the substrate and expected to produce gradient functional film by the heat of the Laser on the present work.
At first, the mixture of the graphite and boron powder is irradiated by the YAG Laser beam. And the sintered material is analyzed by X-ray diffraction. Boron carbide (B_4C) is composed by this method. Next, the mixture is spread on the substrate, and the YAG Laser beam is scanning on the substrate. The hardness of the boron carbide film is 16 GPa. At last, this method is applied for the producing high aspect ratio micro parts made of boron carbide. The hardness of the film is expected to increase by composing by other ceramics.
