Strengthening of Silicon Carbide Ceramics by Surface …

Surface strengthening of SiC by in situ surface nitridation during post‐hot isostatic pressing (post‐HIPing) in N 2 was investigated. The formation of a thin (5–15 μm) layer of submicrometer β‐Si 3 N 4 on the surface of SiC was obtained at 1850 C and 200 MPa. While

Silicon carbide (SiC) ceramic is an ideal material for mechanical seal because of its super hardness, high strength, low friction coefficient, good thermal conductivity, and resistance to friction and wear. However, due to relatively high resistivity of SiC ceramic, the triboelectric charge caused by rubbing of mechanical seal end-faces could not be released. It is terrible that the
