Description
Technical Field
[0001] The invention relates to the technical field of spark plasma sintering, in particular to a spark plasma sintering device based on a pulse current generator. Background Art
[0002] Spark plasma sintering mainly uses the electric field formed by an external pulsed strong current to clean the surface oxides and adsorbed gases of powder particles, purify materials, activate the powder surface, and improve the diffusion capacity of the powder surface. Then, the powder is heated for a short time by a strong current under a relatively low mechanical pressure for sintering and densification. The electric energy consumed by spark plasma sintering is only 1 / 5 to 1 / 3 of that of the traditional sintering process (hot pressing sintering, hot isostatic pressing). It has many advantages such as fast heating rate, short sintering time, high density, uniform grains and controllable organizational structure, energy saving and environmental protection, high efficiency and low energy. It can be used to prepare metal materials, ceramic materials, composite materials, nano-bulk materials, amorphous bulk materials and gradient materials. The spark plasma sintering process is to load the raw material powder into the cavity of the mold, and apply the pulse current to the sintered raw material powder through the pressure rod and the energized electrode, and a certain pressure must be applied during the sintering process. Therefore, spark plasma sintering must be used in conjunction with a special mold.
[0003] The existing spark plasma sintering device will cause the electrode surface to wear or damage during long-term use or high-intensity discharge process. If pits, cracks or obvious wear appear on the electrode surface, it will affect the stability of discharge and processing quality. At this time, it is necessary to consider replacing the electrode. The installation and replacement of the electrode are fixed by bolts, which makes the disassembly process more cumbersome. In addition, after long-term use, the vacuum box of the sintering device needs to be cleaned and inspected. The disassembly process is also cumbersome, which affects the convenience of using the spark plasma sintering device. Therefore, a spark plasma sintering device based on a pulse current generator is proposed to solve the above-mentioned problems. Summary of the invention
