Effect of reaction melt infiltration temperature on the ablation properties of 2D C/C–SiC–ZrC composites

Effect of ZrB2 and SiC distributions on the ablation of modified carbon/carbon composites

“…4(b), (c), (e) and (f), it can be found that a lot of white phases covers on the front surface of sample and forms a layer of ablation products. This phenomenon was also reported in other works [24,25]. Some defects could be observed on this white layer of SZ-2 while that layer of SZ-1 is relatively integrated.…”

SiC nanowire toughened ZrB2–SiC ablative coating for SiC coated C/C composites

“…High temperature during ablation and fast cooling after ablation would lead to a large temperature gradient in the edge region of the coated samples [25,26]. Macrocracks(as seen in Fig.…”

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

“…A C C E P T E D ACCEPTED MANUSCRIPT 2 Zirconium carbide (ZrC) has attracted increasing interest due to its high melting point (3540 o C) [1], great hardness (25.5 GPa) [2], relatively low density (6.64 g cm −3 ) and good ablation resistance [3][4][5][6], which make it attractive for aerospace applications such as hypersonic flight, atmospheric re-entry and rocket propulsion [7,8], where the operating temperature can be in excess of 3000 o C [6]. However, monolithic ZrC ceramic is very brittle and not practical for many applications [9,10].…”
