Synthesis and consolidation of TiN/TiB2 ceramic composites via reactive spark plasma sintering

Effect of SPS parameters on densification and properties of steel matrix composites

“…SPS process also guarantees uniform and homogenous microstructure in the whole volume of sintered materials. These benefits make SPS suitable for the development of many innovative materials difficult to be produced by traditional methods, such as ceramics [15,16], nanocrystalline materials [17,18], functionally graded materials [19] and composites [20][21][22] Ceramic materials, such as carbides and borides, are candidates for advanced strengthening phase in steel matrix composites due to their exceptional hardness and stability with the steel matrix. Titanium diboride (TiB 2 ) also exhibits many unique physical properties such as high hardness, good electrical and thermal conductivities, high melting point, chemical stability, and high wear resistance [23,24].…”

Low temperature sintering of ZrC–SiC composite

“…High-energy plasma can bring about some phenomena that can enhance densification such as particle surface activation, local melting, and evaporation on the surface of the powder particles [12,13]. High-energy ball milling (HEBM) is usually adopted to enhance the sinterability of raw powders.…”

Synthesis of B₆O powder and spark plasma sintering of B₆O and B₆O–B₄C ceramics

“…This can be attributed to the formation of the B 13 C 2 phase, which has a slightly lower 2ª for the main diffraction line. It has been reported that no variation in lattice constants for B 6 O or B 4 C, and no formation of a solid solution or new compound under high pressure (3 5 GPa) 11) and high temperature (17001900°C) 23) conditions are observed, but they may have occurred during SPS processing. Moreover, no other diffraction lines were observed (Fig.…”
