  • The adverse effects of tungsten carbide grinding on

    Tungsten-carbide burs (6- and 8-blade) are not recommended for zirconia grinding due to the significant reduction of biaxial-flexural strength and observed micro-structural surface and subsurface damage.

    Tungsten Carbide vs. Zirconia :: MakeItFrom

    2020-5-30 · Tungsten carbide belongs to the non-oxide engineering ceramics classification, while zirconia belongs to the oxide-based engineering ceramics. There are 19 material properties with values for both materials. Properties with values for just one material (3, in this case) are not shown.

    The adverse effects of tungsten carbide grinding on

    2020-4-1 · Therefore, there is a need to consider alternate ways to finish tungsten carbide ground zirconia that can remove surface micro-cracks and restore the strength. Polishing is a known method to smoothen ceramics thereby eliminating the defects created by grinding and in turn prevent or minimize wear of the opposing teeth [,,]. It is not known if

    Incongruent reduction of tungsten carbide by a

    2011-1-31 · The reduction of tungsten carbide (WC) to elemental tungsten by reaction with a Zr–Cu melt was examined. Dense WC disks were immersed in a vertical orientation in molten Zr 2 Cu at 1150–1400 °C for 1.5–24 h. Continuous, adherent layers of W and ZrC formed at WC/melt interfaces.

    Comparison of wear and temperature of zirconia and

    The wear of conical burrs made from ZrO2 and tungsten carbide was measured using scanning electron microscopy (SEM) and image processing software. Temperature was measured by an infrared thermometer. As well as 3-dimensional FEA, the temperature and wear of the burrs was predicted with the aid of the Johnson-Cook model for bone material properties.
