spark plasma sintering furnace advantages
spark plasma sintering furnace advantages:
1. Due to the strong pulse current applied between the powder particles, the spark plasma sintering can produce many beneficial effects for rapid sintering. Compared with conventional sintering technology, spark plasma sintering integrates plasma activation, hot pressing and resistance heating. It has the advantages of fast heating speed, short sintering time, low sintering temperature, uniform grains, favorable for controlling the fine structure of sintering body, high density of materials, simple operation, high reproducibility, safety and reliability, space saving, energy saving and low cost Advantage.
2. However, the basic theory is not completely clear at present, and needs a lot of practice and theoretical research to improve, and needs to increase the multi-function of equipment and the capacity of pulse current, so as to make larger products; especially needs to develop fully automated production system to meet the production needs of complex shape, high-performance products and three-dimensional gradient functional materials.
3. The main feature of the spark plasma sintering furnace is to realize the super fast densification sintering of materials by bulk heating and surface activation, which has obvious advantages. It has the advantages of fast heating speed, short sintering time, low sintering temperature, uniform heating, high production efficiency, energy saving, etc. in addition, due to the comprehensive effect of plasma activation and rapid heating sintering, the growth of grains is inhibited, the microstructure of original particles is maintained, thus essentially improving the performance of sinter, and making the subsequent products have the structure It is fine and uniform, can keep the natural state of raw materials, and has high density.
4. Simple and safe operation.
5. The equipment of spark plasma sintering furnace can work in vacuum or protective atmosphere, with the functions of power-off, water cut-off, under voltage, over temperature alarm and electrical interlock, humanized control software, touch screen full-automatic control and record, with full-automatic program control of vacuumizing, pressurizing and sintering, with real-time digital display and record of pressure, displacement and vacuum degree, so as to facilitate the analysis of sintering process Cheng.
spark plasma sintering furnace application scope:
Rapid and high-grade sintering of metals, ceramics, nano materials, amorphous materials, composite materials, functional gradient materials, etc.
