摘要: In this work, we develop an instrument to study the ablation and oxidation process of materials such as C/SiC (carbon fiber reinforced silicon carbide composites) ultra-high temperature ceramic in extremely high environment. The is integrated with speed cameras filtering lens, infrared thermometers water vapor generator for image capture, measurement, humid atmosphere, respectively. thermal shock well on both sides specimen can be situ monitored. results show clearly dynamic liquid oxide flowing. addition, algorithm post-processing captured images obtain deformation specimens, order better understand behavior subjected temperature.
