“…Graphite and carbon exhibit unique properties such as low density, high specific strength, high elastic modulus, low coefficient of thermal expansion and excellent thermal shock resistance [1,2]. Especially owing to the retention of strength at high temperatures, they are regarded as one of the most outstanding candidates for high-temperature structural materials and thermal protection systems in aerospace applications [3-7].…”

In this research, the high-duration ablation resistance of SiC-gradient coating was investigated. SiC coating was prepared on graphite by reactive melt infiltration method at 1873 K under the argon atmosphere. Formation of the SiC layer with gradient distribution of Si and C elements was confirmed by X-ray diffraction patterns and scanning electron microscope micrographs. The results of the ablation test showed that SiC-graded coating with a proper adhesion could protect the graphite substrate up to 2073 K. The mass ablation rate for the SiC-graded coating after the 60 and 360 s ablation test under supersonic flame were −0.346 × 10 −3 g/ cm 2 s and −0.022 × 10 −3 g/cm 2 s, respectively. The results indicated that the ablation mechanism of the SiC coating under supersonic flame is the SiO 2 scouring from the central ablation region to the outer ablation region in the layer by layer form.

“…However, some weaknesses include low hardness and unsatisfied strength, which may limit the potential application of Ti 3 AlC 2 as a high-temperature structural material [9][10][11][12]. Some conventional ceramics such as SiC [13], BN [14], TiC [15], Al 2 O 3 [16][17], TiB 2 [18] et al have been taken as a second phase to overcome drawbacks of Ti 3 SiC 2 or Ti 3 AlC 2 [19][20] for their high hardness, good wear resistance and excellent chemical stability.…”

Ti 3 AlC 2 /Al 2 O 3 composite materials were successfully fabricated from TiO 2 /TiC/Ti/Al powders by the in situ reactive hot pressed technique. The microstructure, mechanical and oxidation properties of the composites were investigated in the paper. Vickers hardness increased with the Al 2 O 3 content. The relative density of Ti 3 AlC 2 /Al 2 O 3 composites exhibits a declining tendency with Al 2 O 3 content especially exceeds 10 vol. %. The Ti 3 AlC 2 /Al 2 O 3 composites show excellent electrical conductivity. The flexural strength and fracture toughness of Ti 3 AlC 2 /10 vol. % Al 2 O 3 are 461 ± 20 MPa and 6.2 ± 0.2 MPa m 1/2 , respectively. The cyclic oxidation behaviour of resistance of Ti 3 AlC 2 /10 vol. % Al 2 O 3 composites at 800-1000°C generally obeys a parabolic law. The oxide scale of sample consists of a mass of α-Al 2 O 3 and TiO 2 , forming a dense and adhesive protect layer. The result indicates that the Al 2 O 3 can greatly improve the oxidation resistance of Ti 3 AlC 2 .
