  • Patent number: 10954165
    Abstract: The present disclosure relates to polycrystalline cubic boron nitride (PCBN) with enhanced impact-resistance and wear-resistance and a method for producing the PCBN. According to the present disclosure, producing the polycrystalline cubic boron nitride with one or more kinds of protrusion-shaped borides formed on the cubic boron nitride surface may inhibits the development of cracks along the surfaces of the cubic boron nitride particles and binders, thereby to improve the impact-resistance and wear-resistance. In this way, the life-span of the machining tools may be enhanced. Further, the polycrystalline cubic boron nitride may have at least one kind of a compound composed of at least two selected from the group consisting of BN, Ti, W, Co, Zr, and Si as formed during sintering. This may allow the PCBN to have high bonding strength between the cubic boron nitride and the binder.

  • Patent number: 10245686
    Abstract: The present invention relates to a conditioning method of gas turbine engine components (e.g. compressor blades and vanes) for aerodynamic noise reduction. The gas turbine engine components are plasma treated in a high vacuum environment to generally reach a surface roughness (Ra) below 150 nanometers and in some cases below 25 nanometers. Then during the same process the components are coated using either a metallic or ceramic, hard, thin coating ranging from 100 to 3000 nanometers in thickness depending on desired surface smoothness and non-fouling properties. The same treatment combined with a surface relaxation process, which is part of a smoothing process, allows applying even up to 100 micrometers of hard coating without changes to high cycle fatigue properties and overall performance. Improved surface smoothness of the components and enhanced non-adhesiveness of the contaminants advance the quality of the flow through the gas path and compressor aerodynamic noise reduction.

A polycrystalline diamond compact includes diamond grains bonded by inter-granular bonds and an alloy disposed within interstitial spaces. The alloy includes iridium, carbon, and at least one of copper, silver, and gold. An earth-boring tool includes a bit body and a polycrystalline diamond compact secured to the bit body. Some methods include selecting an alloy that is catalytic to formation of diamond-to-diamond bonds when the alloy is in a liquid phase, but non-catalytic to the back-conversion of diamond to graphite at temperatures of less than about 1,000° C.

  • Patent number: 9889540
    Abstract: A polycrystalline diamond compact (PDC) has a diamond matrix including inter-bonded diamond grains and nanodiamond agglomerates within interstitial spaces in the diamond matrix. A volume percentage of the nanodiamond agglomerates in the PDC may be greater than or equal to a percolation threshold volume of the nanodiamond agglomerates in the PDC, and a remainder of the volume of the PDC may be at least substantially comprised by the diamond matrix. The PDC may be at least substantially free of metal solvent catalyst material. Earth-boring tools include one or more such PDCs. A method of manufacturing a PDC includes mixing diamond grains with nanodiamond agglomerates to form a mixture, and subjecting the mixture to a high-temperature/high-pressure (HTHP) sintering process to form the PDC without any substantial assistance from a metal solvent catalyst material.

  • Patent number: 9691871
    Abstract: Local variability of the grain size of work function metal, as well as its crystal orientation, induces a variable work function and local variability of transistor threshold voltage. If the metal nitride for the work function metal of the transistor gate is deposited using a radio frequency physical vapor deposition, equiaxed grains are produced. The substantially equiaxed structure for the metal nitride work function metal layer (such as with TiN) reduces local variability in threshold voltage.

  • Patent number: 9662712
    Abstract: An adherent coating for carbide and ceramic substrates employs a thin layer between the substrate and a subsequent layer or layers. The thin layer may be employed without thermal cracking due to heat during use, such as for the insert of a cutting tool, because the upper layer or layers provide a gradual transition of material properties to a harder, less thermally conductive material on the outermost layer. A particular arrangement of layers on the carbide or ceramic substrate may be, from innermost to outermost layer, hafnium nitride, titanium carbide, aluminum oxide, and titanium nitride.
