Abstract

Ta0.8Hf0.2C exhibits excellent thermal protection properties， making it well-suited for high-temperature ablation environments. MoSi2， an outstanding sintering agent， is frequently employed in anti-ablation coatings. To investigate the impact of MoSi2 content on the ablative performance of Ta0.8Hf0.2C-SiC-MoSi2 coatings， we employ the slurry-sintering method to prepare coatings with varying MoSi2 concentrations on C/C composites， which are pre-coated with SiC transition layers. We conduct a comprehensive analysis of the phase composition， micromorphology， and ablation behavior of these coatings. The findings reveal that， at a MoSi2 content of 10% （mass fraction）， the coating exhibits optimal ablative properties， with a mass ablation rate of 1.24 mg·s-1 and a line ablation rate of 0.02 μm·s-1. This superior performance is attributed to MoSi2 ability to hinder the active oxidation of SiC， thereby reducing its consumption. Additionally， the high-viscosity liquid layer formed during ablation effectively resists the erosion of high-temperature flames， further preventing the diffusion of oxygen.
