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.
