In this work, to improve the friction and wear properties of carbon fiber (CF) reinforced resin-based composites (CFRC), silicon carbide (SiC) @ γ-Aminopropyl triethoxysilane (Kh550) was self-asseled on the surface of CF. Compared to the unmodified CFRC, the

Materials | Free Full-Text | Decreasing Resistivity of …

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

Effect of pH on the dispersability of silicon carbide …

1/4/1999· The dispersion behaviour of commercial silicon carbide (SiC) powders of various grit sizes in deionised water was studied over the pH range 2–11. The slips were characterised for the state of their dispersion by employing the various quantitative diagnostic techniques e.g. particle size distribution, sedimentation, rheological behaviour, viscosity and zeta potential.

7/5/2013· Silicon carbide is a polymorphic material with over 250 known crystal structures. Here the authors show that such polymorphism can be used as a degree of freedom for engineering optically

Effects of Surfactants and Surface Treatment on Aqueous …

The effects of the addition of surfactants and of the surface treatment upon the aqueous dispersion of silicon carbide were examined. In the case of β-SiC, the addition of nonionic surfactants having relatively longer lengths of hydrocarbon and oxyethylene chain to the β-SiC treated with a silane coupling agent enhanced the dispersion stability.
