Spark plasma sintering system
With this new sintering technique the tool and the component are directly heated by DC current pulses to reduce cycle times to a few minutes. The use of DC current pulses causes an additional increase in sintering activity in various materials due to the processes that occur at the points of contact of the powder particles (Joule heating, generation of plasma, electro migration etc.). Therefore, a significantly lower temperature as well as significantly lower mould pressure is needed than is used for conventional hot pressing and sintering.
