Abstract
Section titled āAbstractāPolycrystalline diamond (PCD) films prepared by chemical vapor deposition (CVD) can improve surface properties of hard materials. In this study, the growth rates of PCD film prepared by hot-filament CVD have been investigated on the influence of CH <sub xmlns:mml=āhttp://www.w3.org/1998/Math/MathMLā xmlns:xlink=āhttp://www.w3.org/1999/xlinkā>4</sub> concentration. Tribological properties of PCD films on sintered SiC substrates were investigated for application on the mechanical seals of pumps. The critical sealing pressure for friction and wear resistance properties of PCD films paired with PCD films were investigated under practical ring on ring sliding test conditions, and compared with conventional materials of mechanical seals. The results show that friction and wear resistance properties of PCD films are superior to that of conventional materials for high sealing pressure.
