Fabrication of nanocomposite Ti(C,N)-based cermet by spark plasma sintering

Spark Plasma Sintering as a Useful Technique to the Nanostructuration of Piezo‐Ferroelectric Materials

“…[30] SPS has been demonstrated to enable the consolidation of ceramics materials within minutes and the ability to obtain fully dense samples at comparatively low sintering temperatures, typically a few hundred degrees lower than in normal hot pressing. The most commonly compacted materials by this technique are: carbides, for example, SiC, Ti 3 SiC 2 , WC and ZrC; [30][31][32][33][34][35][36][37][38] nitrides, for example Si 3 N and AlN; [39][40][41] oxides, for example, ZrO 2 , [27,28,42] Al 2 O 3 [9,11,43] and several perovskites; [10,[44][45][46][47][48][49] phosphates, for example, Nasicon [50] and Hydroxyapatite; [51,52] metals; [53][54][55][56] intermetallics; [57] and, borides. [58,59] The use of rapid sintering appear to be essential for the fabrication of nanocrystalline ceramics [46,49] and to get special microstructures.…”

Spark plasma sintering of TixTa1−xC0.5N0.5-based cermets: Effects of processing conditions on chemistry, microstructure and mechanical properties

“…Spark plasma sintering (SPS) has been attracting the attention of many researchers [11][12][13] because it is a process by which fine grained materials can be 3 fabricated by sintering powders to their full density at low temperatures within a few minutes [14,15]. The advantage offered by this process is related to its significant features that include the use of high heating rates and high pressures, and the effect of the current or electric discharge on mass transport [16][17][18].…”

“…The advantage offered by this process is related to its significant features that include the use of high heating rates and high pressures, and the effect of the current or electric discharge on mass transport [16][17][18]. There is currently a growing interest in extending these results to non-oxide ceramics and cermets that are difficult to sinter, especially titanium carbonitrides [12,19,20].…”

Effect of VC addition on the microstructure and properties of Ti(C,N)-based nano cermets

“…Ti(C,N)-based cermets reinforced by nano-Si 3 N 4 particles greatly modified microstructures that were beneficial to the excellent mechanical properties [8]. Moreover, The research on the effect of nano TiC and TiN additions in Ti(C,N)-based cermets showed that nano additions played a critical role in determining cermets microstructure and could obviously improve the toughness of Ti(C,N)-based cermets [9][10].…”
