The Technology

Ceramic materials have a polycrystalline microstructure possessing superior mechanical properties and in particular strength, wear resistance and stability in aggressive and high temperature environments.
Nanocomposites are defined as a ceramic matrix that is reinforced with sub-micron particles of a secondary phase. The submicron or nanometer length-scale reinforcing particles are typically randomly located within the ceramic matrix. However, lack of control of the reinforcing nano-particles location can result in poor strength and wear resistance properties.
This technology demonstrate the ability to control of the relative velocity of the grain boundaries and the sub-micron particles during sintering which is critical to engineering the microstructure of ceramic matrix nanocomposites with desired properties.

Advantages

  • Enhanced mechanical properties, including fracture strength and hardness.
  • Control of the location of sub-micron reinforcing particles within an evolving polycrystalline ceramic matrix during sintering.

Applications and Opportunities

  • Cutting tools
  • Milling tools and grinding tools
  • Capillaries for wire-bonding
  • Ballistic armor
  • Break-pads for cars
  • Wear resistant fittings for abrasive liquids.
