  • Diamond Silicon Carbide Composite Powder Description:
    Abstract:

    Fully dense, diamond-silicon carbide composites are prepared from ball-milled microcrystalline diamond/amorphous silicon powder mixture. The ball-milled powder is sintered (P=5–8 GPa, T=1400K–2300K) to form composites having high fracture toughness. A composite made at 5 GPa/1673K had a measured fracture toughness of 12 MPa·m1/2. By contrast, liquid infiltration of silicon into diamond powder at 5 GPa/1673K produces a composite with higher hardness but lower fracture toughness.X-Ray diffraction patterns and Raman spectra indicate that amorphous silicon is partially transformed into nanocrystalline silicon at 5 GPa/873K, and nanocrystalline silicon carbide forms at higher temperatures.

  • Diamond Silicon Carbide Composite Powder Typical Applications:
    One of the highest single costs in oil drilling is drill-bit wear and breakage. Ultrastrong diamond silicon carbide composites should yield impact tools with significantly longer functional lives. Furthermore, harder materials could be cut faster, which would reduce drilling time and expense. Mechanical parts in other applications would wear longer and require less maintenance.
