“…Unfortunately, ℃ in the gas turbine engines, the high-velocity, highpressure, and high-temperature gas stream contains ~10 vol% of water vapor [339]. Under such harsh environment conditions, the CMCs are subject to active oxidation and recession owing to the formation and volatilization of Si(OH) 4 , leading to catastrophic degradation [71,89,283,341,342]. Accordingly, the SiC-based CMCs also need protective coatings, namely environmental barrier coatings (EBCs).…”

“…The glass phases produced by the oxidation of SiBCN matrix made contribution to the high strength retention ratio. The tensile creep property of SiC/(SiC-SiBCN) x was further investigated at 1200 ℃ in an atmosphere of 12 kPa H 2 O:8 kPa O 2 :80 kPa Ar, and the applied stress was 90, 100, and 120 MPa [138]. The creep curves of specimens tested at 90 and 100 MPa exhibited two-stage characteristic, and one-stage behavior can be seen when tested at 120 MPa.…”

“…In the report of Jiang et al [ 10 ], 3D SiC/SiC composites, with different interfaces, were placed under static oxidation at 1100 °C for 400 h, and their flexural properties and fracture modes were compared. Sun et al [ 11 ] compared two different SiC/SiC-SiBC composite materials against static air oxidation at 800, 1000 and 1200 °C for 100 h. Luan et al [ 12 , 13 ] studied different SiC/SiC-SiBCN composite materials at different temperatures (1200–1400 °C), their long-term static oxidation in different atmospheres, and their creep behaviors under certain environments.…”
