Abstract

To improve the density and ablation resistance of ZrB₂-SiC coatings, TaSi₂ modified ZrB₂-SiC coatings was prepared on C/C composites by low-pressure plasma spraying. Systematical investigations about microstructures of two kinds of ceramic coatings were performed by XRD, SEM, EDS, TEM and X-ray computed tomography. The presence of Ta element in the ZrB₂-SiC-TaSi₂ coating is mainly in the form of fine particles with nanoscale, (Zr_0.8Ta_0.2)B₂, visible fine particles and densification areas. The addition of TaSi₂ is conducive to reducing the porosity of the coatings and improving their mechanical and ablation resistance properties.
