Web1 apr. 2024 · Parish et al. [15] studied the hydrothermal corrosion behavior of SiC prepared by nano-infiltration by transient eutectic (NITE) process in water with 3.57 ppm H 2 at 330 °C and 15 MPa. For NITE SiC with Y 2 O 3 and Al 2 O 3 as oxide additives, its corrosion was more serious than CVD SiC. WebThe hydrothermal method can be used for producing carbon coatings with thickness up to 2 μm on the surface of silicon carbide fibers. The degrading of the mechanical properties after oxidation and corrosion was controlled by the thickness of the oxide or carbon layer.
