Abstract

Mo–57Si–10B (at.%) coating was prepared by the spark plasma sintering (SPS) technique on a 2D woven C_f/SiC composite, and the oxidation behavior of the bare and the coated C_f/SiC samples at 1300 °C were investigated. The coating was composed of a fine MoSi₂/MoB/SiO₂/Mo₂B₅ out layer and the inner SiO₂ interface layer. The mass gain percentage was approximately 0.25% after oxidation at 1300 °C for 100 h. The coated C_f/SiC substrate was effectively protected, owing to the rapid formation of the dense and protective borosilicate layer on the coating, the excellent microstructure stability of the coating and the inner SiO₂ interface layer.
