Methodological aspects of experimental studies of the influence of electric current on the interaction between metals during spark plasma sintering

Spark plasma sintering (SPS) has become a very popular method of powder consolidation and materials synthesis. The processes of SPS of metallic systems are actively studied, including issues related to the reactive formation of alloys and composites. In the present work, the methodological aspects of experimental studies of the influence of electric current on the processes of interfacial interaction in metallic systems during SPS are considered. Examples showing the possibilities of experimental observation and validation of effects pertaining to SPS are given. Recommendations are formulated to set the experimental studies of the related phenomena.
