On the Preparation of Advanced Materials via Pulsed Electric Current Sintering Procedures
Příprava pokročilých materiálů s využitím technik slinování elektrickým proudem
Streszczenie
A general overview on the processing of a series of advanced engineering materials,
synthesized via pulsed-electric-current-sintering related techniques, and the similarities in between
those techniques are introduced in this work. This paper is focused on two major techniques; namely,
the Spark Plasma Extrusion (SPE) and Current Assisted Infiltration Sintering (CAIS), which in turn are
derived from the Spark Plasma Sintering (SPS) technique, all widely used by this research group. Not
only the geometry but also the microstructure of thus prepared specimens might vary depending on the
selected technique. The resulting specimens can be under the forms of discs (flat or thick coin-like),
rivets (enlarged cylindrical bars)-like and/or disclosing interpenetrated periodic networks with regular
or irregular (either coin or rivet/screw)-like specimens, respectively. As for the CAIS technique, either
3D printed ceramic frameworks or naturally synthesized porous substrates (such as bone-like
structures), can be infiltrated with virtually any metal or alloy. Among the series of produced materials
we can include, for example: biomaterials such as: Ti- and Mg-hydroxyapatite, pure hydroxyapatite
HA, composites, e.g., Al5083-CNT´s, just to name a few. The expanding possibilities of SPS, SPE and
CAIS techniques are briefly indicated here.
