Spark Plasma Sintering (SPS) also known as Pulsed Electric Current Sintering (PECS) or Field Assisted Sintering Technique (FAST) is a process used in materials engineering to create solid materials with special properties from powders, sometimes called nanomaterials.
The process of Spark Plasma Sintering is as follows: powdered material is placed in the sintering chamber and compressed while a pulsed DC current is passed directly through the compacted powder via a graphite die.
Materials which can be sintered with this method include metals and ceramics.
Many industries utilize materials produced from Spark Plasma Sintering including, military, medical, industrial, automotive, and computer.
The process time with Spark Plasma Sintering is dramatically reduced compared to other sintering methods. Process temperature is also reduced compared to other sintering methods. No binders are necessary which increases finished material hardness and strength and decreases process time. Operating expenses are lower than traditional sintering methods mainly due to the shorter cycle time.
