Spark plasma sintering (SPS) also known as pulsed electric current sintering (PECS) or field-assisted sintering technique (FAST), belongs to a class of powder metallurgy techniques. The fundamental of this technique is appeared over last 50 years ago, but modern SPS technique is appeared within the last 20 years depending on this principle. The variation of this factor is so extensive for each material that only a few papers have been devoted to this research. This review paper summarizes the latest research findings with respect to experimental procedures, densification behaviors, microstructural characteristics, and mechanical properties of various materials synthesized using SPS, mainly highlighting the influence of the electric DC pulse current on the relative density, mechanical and tribological properties of various materials during sintering.
