  • Publication number: 20150119302
    Abstract: Embodiments of the present invention may provide textured surfaces to be lubricated, the texturing to enhance the effectiveness of the intended nano-lubrication. The texturing may make asperities and depressions in the surface to be lubricated. This texturing may be executed, for example, by chemical etching, laser etching, or other techniques. This texturing may create locations in the lubricated surface to hold or anchor the intended nano-lubricants, to facilitate the creation of a tribo-film on the surface when the lubricated surface is used under pressure, and resulting in delivery of multiple chemistries from the nano-lubricant.

  • Publication number: 20140308511
    Abstract: A physical configuration of multiple-layer coatings formed with at least one layer of coating containing cubic born nitride (cBN) particles with one or more layers in composite form containing cBN particles may have a thickness of each individual layer as thin as in the nanometer range, or as thick as in the range of a few microns and even up to tens of microns. The chemistry of the composite layer consists of any individual phase of (a) nitrides such as titanium nitride (TiN), titanium carbonitride (TiCN), and hafnium nitride (HfN); (b) carbides such as titanium carbide (TiC); and (c) oxides such as aluminum oxide (Al2O3) or any combination of the above phases, in addition to cBN particles. The coating or film can be stand-alone or on a substrate.

  • Publication number: 20140302995
    Abstract: In one aspect, the present invention relates to a method of forming a reworkable, thermally conductive and electrically resistive material as a bonding structure in a module and application of the same. In certain embodiments, a homogeneous solution is prepared with an anisotropic structure, such as single-wall carbon nanotubes (SWCNTs), and an epoxy resin. The homogeneous solution is applied between a carrier and a chip of the module, and cured at a curing temperature for a curing time period to form a reworkable epoxy bonding layer, which has an anisotropic structure loading factor of about 0.1%-1.0% such that the reworkable epoxy bonding layer is thermally conductive and electrically resistive. When the chip is identified as a faulty chip, the module may be heated at a debonding temperature for a debonding time period such that the reworkable epoxy bonding layer debonds, and the chip becomes detachable from the carrier.

  • Publication number: 20140215925
    Abstract: A method for forming a stand-alone wafer or a coating on a substrate uses a composite of cubic boron nitride (cBN) particles and other materials, such as nitrides, carbides, carbonitrides, borides, oxides, and metallic phase materials. The wafer or coating may be formed of a thickness up to about 1000 microns for improved wear life. The density of material within the wafer or coating may be varied according to desired parameters, and a gradient of particle sizes for the cBN may be presented across the thickness of the material.

  • Publication number: 20140212232
    Abstract: A cutting tool formed by a coating layer on a substrate has cutting edges that feature serrations. The linear dimensions of the serrations may vary from a few nanometers up to 10 microns. The serrations result in a smoother cut edge on the workpiece, particularly when the workpiece is formed of certain materials that are seen as particularly difficult to cut, such as hardened steels.

  • Patent number: 8758863
    Abstract: Methods for creating coatings composed of a single material or a composite of multiple materials, beginning with ESC to deposit the base layer and then using other methods for the binding step beyond CVI. Also, for certain materials and applications, some pre-processing or pre-treatment of the coating materials is necessary prior to deposition in order to achieve a satisfactory coating. This application discloses methods for pre-deposition treatment of materials prior to ESC deposition. It also discloses methods for post-processing that provide additional functionality or performance characteristics of the coating. Finally, this application discloses certain apparatus and equipment for accomplishing the methods described herein.

  • Publication number: 20140005085
    Abstract: Embodiments of the present invention may include a macro-composition with a special structure. The structure includes a layered macro-composition made of a nanoparticle as an inner nucleus, an intermediate layer around the nucleus, and an outer layer intercalated with the nucleus or encapsulating the nucleus and the intermediate layer. A plurality of the layered macro-compositions is bonded together by bonds, so that each layered macro-composition is bonded to at least one other such layered macro-composition. Embodiments include a macro-composition made of three 3-layered macro-compositions joined in a chain by two bonds. These macro-composition assemblies may take the shape of layered macro-compositions bonded together in chains, or forming other shapes, such as rings. The layered macro-composition may be no more than about 100 nanometers in size, for example. The bonds of the complex macro-composition may have an average length of no more than about 100 nanometers, for example.

  • Publication number: 20130216777
    Abstract: A coating for carbide substrates to produce cutting tool inserts employs a lower nanostructured layer in conjunction with a non-nanostructured layer. The nanostructured layer is produced by the addition of a refining agent flow, particular hydrogen chloride gas, during deposition. The combination of a nanostructured layer and non-nanostructured layer of coatings is believed to produce a cutting tool insert that exhibits longer life, particularly in conjunction with particularly difficult cutting applications such as the cutting of hardened steel with severe interruptions.

  • Publication number: 20130216806
    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.
