Effect of heat flux on ablation behaviour and mechanism of C/C–ZrB2–SiC composite under oxyacetylene torch flame

Effect of interlayer on the ablation properties of laminated HfC–SiC ceramics under oxyacetylene torch

“…The formation of silica glass layer may provide an efficacious protective oxidation barrier due to its low oxygen permeability. This process is similar to what has been reported for SiC-containing materials [32,38,39]. In this stage, the ablation rate was mainly controlled by the oxidation of HfC and SiC.…”

Microstructure and oxidation behavior of C/C–ZrB 2 –SiC composites coated with SiC coating at high temperature

“…By adding SiC ceramics, the oxidation resistance and high temperature strength of ZrB 2 -based ceramics can be further increased [13][14][15][16]. But most of the work focused on improving the ablation resistance of C/ZrB 2 -SiC composites in the previous research [17][18][19][20]. Little work has been done about the long-term oxidation resistance of C/C composites modified by UHTCs at high temperatures.…”

Effect of Monolithic LaB6 on the Ablation Resistance of ZrC/SiC Coating Prepared by Supersonic Plasma Spraying for C/C Composites

“…simulated under oxyacetylene environment with high heat flux of 4.18 MW/m 2 ) was the main ablation behavior, relative to oxidation (relatively primary at heat flux of 2.38 MW/m 2 for oxyacetylene ablation [19] [20] , in this study, monolithic LaB 6 was attempted to dope ZrC coating by SAPS. The ablation resistance of the doped coating was evaluated at high heat flux of 4.18 MW/m 2 .…”
