Abstract

To improve the ablation resistance of graphite, ZrB₂-SiC/SiC coating was prepared by pack cementation. Ablation resistance of the coating was investigated by oxyacetylene torch. After ablation for ∼200 s, the linear and mass ablation rates of ZrB₂-SiC/SiC coated graphite at center area were 4.647 μm/s and 1.216 mg/s, respectively. During ablation process, chemical erosion and particle denudation occurred at the same time were the main factors leading to ablation.
