C/C–ZrC composite prepared by chemical vapor infiltration combined with alloyed reactive melt infiltration

Effects of Cf/C density on microstructure and properties of 3-D Cf/ZrC composites prepared by liquid metal infiltration

“…Tong et al [16] also fabricated C f /ZrC composites by using Zr-Si alloy as infiltrator. But due to the high melting points of Zr and Zr-Si alloy, the RMI process had to be operated at temperature above 1800 o C which likely caused damage to the fibers [13].…”

“…However, monolithic ZrC ceramic is very brittle and not practical for many applications [9,10]. Introducing continuous carbon fibers is one of the widely used methods to improve the mechanical properties of ceramic [11][12][13][14][15][16].…”

Fabrication and microstructure of ZrB2–ZrC–SiC coatings on C/C composites by reactive melt infiltration using ZrSi2 alloy

“…From the Zr-Si phase diagram [26], it can be known that the melting point of ZrSi 2 alloy is 1620 and at ℃ this temperature the alloy is consisted of solid β-ZrSi phase and liquid ZrSi eutectic. As temperature increases, more β-ZrSi will transfer to Zr-Si eutectic according to lever principle.…”

Low-temperature solution synthesis of nanosized hafnium carbide using pectin

“…chemical vapour infiltration [13], reactive melt infiltration [14], slurry impregnation [15]. However, these processes have some disadvantages of inhomogeneous dispersion in the composites, especially the intra bundle areas of composites.…”
