Abstract
Laser ablation behaviors of carbon/carbon composites with an underlying SiC layer and a surface ZrC layer were investigated using a continuous wave CO2 laser. The laser powers varied from 100W to 2000W. The results indicate that the two-layer SiC-ZrC coating can improve the laser ablation resistance of the carbon/carbon composites. Three ablation regions can be identified. The ablation mechanisms in different ablation regions are proposed.
