Microstructure and properties of C/C-ZrC composites prepared by hydrothermal deposition combined with carbothermal reduction
چکیده انگلیسی
Carbon fiber reinforced carbon matrix containing ZrC (C/C-ZrC) composites were prepared by hydrothermal deposition combined with carbothermal reduction. The submicron ZrC particles (100-300 nm) were dispersed in the matrix. The stress-strain curves of the composites presented a typical pseudo-plastic fracture behavior. The mass and linear ablation rates of the composites were 3.7 × 10−3 g/s and 4.2 × 10−3 mm/s, respectively. The formation of ZrO2 glass layer reduced erosion of the composites in the ablation center. The continuous C-ZrC-ZrO2 skeleton layer generated from the oxidation of ZrC can protect the composites from erosion at the ablation brim region. The obtained C/C-ZrC composites present a promising potential as ablation resistance materials.
