摘要： A method of making a ceramic matrix composite (CMC) brake component may include the steps of applying a pressure to a mixture comprising ceramic powder and chopped fibers, pulsing an electrical discharge across the mixture to generate a pulsed plasma between particles of the ceramic powder, increasing a temperature applied to the mixture using direct heating to generate the CMC brake component, and reducing the temperature and the pressure applied to the CMC brake component. The ceramic powder may have a micrometer powder size or a nanometer powder size, and the chopped fibers may have an interphase coating.

摘要： A method is disclosed for forming a blended phosphor composition. The method includes the steps of firing precursor compositions that include europium and nitrides of at least calcium, strontium and aluminum, in a refractory metal crucible and in the presence of a gas that precludes the formation of nitride compositions between the nitride starting materials and the refractory metal that forms the crucible. The resulting compositions can include phosphors that convert frequencies in the blue portion of the visible spectrum into frequencies in the red portion of the visible spectrum.

摘要： The present invention provides an Al2O3 coated Si3N4 cutting tool comprising a Si3N4 based substrate body and a coating layer on the substrate body, wherein the coating layer has at least one Al2O3 coating layer consisting of amorphous Al2O3 or nanocrystalline α-, γ-, or κ-Al2O3. The hard and wear resistant refractory coating is deposited onto the Si3N4-based substrate body by reactive sputtering using bipolar pulsed DMS technique or dual magnetron sputtering method at substrate temperatures of 300-700° C. During the deposition, preferably, the substrate temperature is controlled to achieve the desired crystal structure of the coating. To form amorphous Al2O3 coating on the surface of the substrates, the deposition temperature can be controlled from 300 to 500° C.; on the other hand, to form nanocrystalline α-, γ-, or κ-Al2O3, the deposition temperature can be controlled in the range of 500-700° C. The coated cutting tools of the present invention are suitable for high-speed machining of metals by turning, milling, drilling or by other similar chip-forming machining methods.
