  • Patent number: 9587089
    Abstract: Conventional toughening agents are typically rubbery materials or small molecular weight molecules, which mostly sacrifice the intrinsic properties of a matrix such as modulus, strength, and thermal stability as side effects. On the other hand, high modulus inclusions tend to reinforce elastic modulus very efficiently, but not the strength very well. For example, mechanical reinforcement with inorganic inclusions often degrades the composite toughness, encountering a frequent catastrophic brittle failure triggered by minute chips and cracks. Thus, toughening generally conflicts with mechanical reinforcement. Carbon nanotubes have been used as efficient reinforcing agents in various applications due to their combination of extraordinary mechanical, electrical, and thermal properties.

    Abstract: The method of increasing the hardness of wurtzite crystalline materials is directed to the production of tool bits and inserts having a hardness approaching that of diamond, while simultaneously providing greater toughness and fracture resistance than diamond. The method includes forming a workpiece of boron nitride having a wurtzite crystal structure (wBN), and optionally combining boron nitride having a cubical crystal structure (cBN) with the wBN material. The workpiece is heat-treated by a defocused laser beam moved across the surface at a rate sufficient to preclude melting or deformation of the workpiece. The heated area is quickly quenched by a water jet, and a gas jet immediately follows the laser path to assure separation of the water from the laser contact area. The result is an increase in hardness of about 88%, from an initial hardness of about 40 GPa to a treated hardness of about 75 GPa.

  • Publication number: 20130101792
    Abstract: The present invention solves numerous problems in state-of-the-art industrial polymer shaping of micro and nanostructures. The problems of high tool polishing requirements, the inability to define an arbitrary topographical structure on an arbitrary free-form (curved) surface, limited durability and replication quality, as well as providing a convenient method for functionalizing the surface. The invention solves these problems by deploying a ceramic material precursor, which may be coated onto a conventional polymer shaping tool, micro- or nanostructured by mechanical contact (embossing), cured into a hard, durable ceramic material comprising the desired structures. The ceramic material is functionalisable by silane chemistry, due to its high surface density of —OH groups. This apparatus may then be used in a conventional polymer shaping process to make nanostructured polymer replicas.
