Boria Effects on the High Temperature Oxidation of …
CMCs are comprised of silicon carbide (SiC) fibers coated with a boron nitride layer eedded in a SiC matrix. SiC and boron nitride will react with oxygen upon exposure to the engine’s high temperature oxidizing environment, forming silica and boria oxidation products, respectively, which together form a borosilie glass.
Nitride Bonded Silicon Carbide (NSiC) is commonly found as a cast refractory for use under severe service conditions in place of alloys or other refractory materials. Near net shapes can be designed to reproduce the metal parts.

ish grinding of hard materials, are diamond dust or boron carbide powder. Aluminum oxidewheels are used for grinding materials of high ten-sile strength. Silicon carbideis harder but is not as strong as alu-minum oxide. It is used for grinding metals that have
Silicon Carbide Ceramics (SiC) belong to non-oxide ceramic, it not only has excellent mechanical properties at room temperature, such as high bending strength, excellent oxidation resistance, good corrosion resistance, high wear resistance and low coefficient of friction, but also the high temperature mechanical properties (strength, creep resistance Etc.) are known to be the best of ceramic
Corrosion characteristics of silicon carbide and silicon nitride
current view of the corrosion of silicon carbide quite well. For silicon nitride, the oxide scale is ac- tually a double or duplex layer in which an inter- mediate phase of silicon oxynitride occurs between the outer silica scale and the silicon nitride sub- strate [14
