摘要
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 similar to 200 s, the linear and mass ablation rates of ZrB2-SiC/SiC coated graphite at center area were 4.647 mm/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.
