摘要： Disclosed are DC plasma assisted chemical vapor deposition (DC PA-CVD) apparatus operable in the absence of a positive column, a method for depositing a material by DC PA-CVD in the absence of a positive column, and a diamond thin film fabricated thereby. In the method for depositing a material in the absence of a positive column, a discharge is generated between a cathode and an anode disposed to face each other in a reaction chamber by applying a DC voltage therebetween, and introducing reaction gas into the reaction chamber, thereby depositing a material on a substrate mounted on the anode and serving as a part of the anode, wherein the deposition of the material on the substrate is performed under a state that a cathode glow and an anode glow exist in a form of thin layers coating respectively the surfaces of the cathode and the substrate, while a positive column does not exist or is so small as to be negligible. The diamond thin film fabricated by the method is uniform, contains no impurity, and has excellent crystallinity.

摘要： The present method involves heating a blank, a shank and a welding material in an instantaneous heating process wherein a temperature instantaneously rises at a rate of 500-1000° C./min.; and cooling the blank and the shank at a temperature of 700-1200° C. for a short period of time thus integrating the blank and shank into a cutting tool. The instantaneous heating process is preferably a light heating process by a halogen lamp. A welding chamber for the blank controls both pressure and atmosphere, and is provided with a desired degree of vacuum. In this manner, a thermal deterioration of a diamond blank, a welding metal or a shank material is prevented.

摘要： The present invention is related to an apparatus for forming diamond via a chemical vapor deposition process using hot metal filament based on hydrogen and methane gas, and a method thereof. In particular, the present invention provides an apparatus for using the hot filament repeatedly without breakage, in comparison with the conventional apparatus that the filament is limited in one use, and a method thereof. The apparatus that the filament is limited in one use, and a method thereof. The apparatus includes a base substrate wherein diamond is synthesized by heating filament due to supply of voltage, a pair of electrodes being located above the base substrate, and a plurality of hot filaments being placed over the both electrodes. The top portion of the electrodes has a flat surface that is parallel with the filament, and the side portion has a curved surface. A plurality of filaments is smoothly hanged to both electrodes according to the flat surface and the curved surface without fixing. At the flat surface, the filament does not generate heat, so the breakage of the filament due to carburization is prevented. Furthermore, the end of each filament is weighed with individual weight in order to provide the filament with the tension by only gravitation. Even though the length of the filament is changed by temperature change during the diamond forming, the filament is not slacked between the electrodes by the tension. Therefore, by using the apparatus and the method of the present invention, the filament can be repeatedly used without breakage.
摘要翻译：本发明涉及一种通过使用基于氢和甲烷气体的热金属丝的化学气相沉积方法形成金刚石的装置及其方法。特别地，本发明提供了与常规设备相比，在一次性使用中限制纤维的方法与本发明相反地使用热丝而不断裂的设备及其方法。灯丝在一次使用中被限制的装置及其方法。该装置包括基底，其中金刚石由于电压供应而加热灯丝而被合成，一对电极位于基底上方，并且多个热丝放置在两个电极上。电极的顶部具有与灯丝平行的平坦表面，并且侧部具有弯曲表面。根据平面和弯曲表面，多个细丝平滑地悬挂在两个电极上而不固定。在平坦表面，灯丝不会发热，因此防止了渗碳引起的细丝断裂。此外，每个长丝的端部以单独的重量称重，以便仅通过重力为长丝提供张力。即使在金刚石成形期间灯丝的长度随温度变化而改变，灯丝也不会因电压而在电极之间松弛。因此，通过使用本发明的装置和方法，可以重复使用灯丝而不破裂。
