  • Patent number: 6521349
    Abstract: The invention relates to a tool, especially a cutting insert for cutting metallic materials, consisting of a hard metal, cermet, ceramic or steel base body and at least one coating deposited thereon. This single coating or in the event that there are several layers, the outer layer or the layer below the outer layer, consists essentially of molybdenum sulphide. The invention also relates to a method for producing the molybdenum sulphide coating by chemical vapour deposition. According to the invention, the molybdenum sulphide coating contains a mixture of the sulphide phases MoS2 and Mo2S3 with an essentially random orientation (isotropic orientation) of the phase crystals. The coating is applied by means of a chemical vapour deposition procedure.

  • Patent number: 6521350
    Abstract: The invention is a method of bonding a ceramic part to a metal part by heating a component assembly comprised of the metal part, the ceramic part, and a very thin essentially pure interlayer material of a compatible interlayer material placed between the two parts and heated at a temperature that is greater than the temperature of the eutectic formed between the metal part and the metal interlayer material, but that is less than the melting point of either the interlayer material, the ceramic part or the metal part. The component assembly is held in intimate contact at temperature in a non-reactive atmosphere for a sufficient time to develop a homogeneous and strong bond between the ceramic part and the metal part. The bonded component assembly is optionally treated with acid to remove any residual free nickel and nickel salts, to assure a biocompatible component assembly for implantation in living tissue.

  • Patent number: 6514605
    Abstract: A method for producing a durable, non-stick, diamond-tiled implement and the diamond-tiled implement thereby produced. Diamond particles are distributed on a surface of a workpiece containing a ceramic binder. The ceramic binder on the surface of the workpiece is heated to above its glass temperature to fuse the diamond particles in and onto the workpiece. The workpiece is then cooled so that the diamond particles are bonded to and at least partially embedded in the ceramic binder at the surface of the workpiece to produce durable, non-stick, diamond-tiled implements including cookware, bakeware, hot-presses, ski surfaces, skid surfaces, marine articles, and mechanical polishing wheels. Other implements of this invention utilize a high diamond content to produce thermally conducting and electrically insulating coatings for heat spreaders, or conversely, heaters.

    Abstract: A new capping multilayer structure for EUV-reflective Mo/Si multilayers consists of two layers: A top layer that protects the multilayer structure from the environment and a bottom layer that acts as a diffusion barrier between the top layer and the structure beneath. One embodiment combines a first layer of Ru with a second layer of B4C. Another embodiment combines a first layer of Ru with a second layer of Mo. These embodiments have the additional advantage that the reflectivity is also enhanced. Ru has the best oxidation resistance of all materials investigated so far. B4C is an excellent barrier against silicide formation while the silicide layer formed at the Si boundary is well controlled.

    Abstract: A process for creating surface microporosity on a titanium (or other metal) medical device includes creating a surface oxide layer on the device; placing the device, which is connected to a negative terminal of an electrical power supply, into a calcium chloride bath; connecting the positive terminal of the power supply to an anode immersed in or containing calcium chloride thereby forming an electrolytic cell; passing current through the cell; removing the device from the bath; and cooling and rinsing the device to remove any surface salt. If necessary, the device is etched to remove metal oxide which may have formed during the cooling process. The resulting device has a microporous surface structure. Alternatively, only a designated surface portion of a medical device is made microporous, either by applying a non-oxidizing mask, removing a portion of the oxide layer, or subtracting a portion of a microporous surface.

    Abstract: A substrate is coated with a solar management coating system including at least one infrared (IR) reflective layer. A diamond-like carbon (DLC) inclusive protective coating system (e.g., including at least one highly tetrahedral amorphous carbon (ta-C) inclusive layer having sp3 carbon-carbon bonds) is provided on the substrate over at least the IR reflective layer in order to make the coating system scratch resistant, abrasion resistant, and generally mechanically durable. The DLC inclusive protective coating system may be hydrophobic, hydrophillic, or neutral in different embodiments of the invention. Optionally, at least one fluoro-alkyl silane (FAS) compound inclusive layer may be provided on the substrate over at least one of the DLC inclusive layer(s) in hydrophobic embodiments in order to increase contact angle &thgr; of the coated article.

  • Patent number: 6455167
    Abstract: A coating is described for use on a superalloy substrate comprising a diffusion barrier as an intermediate layer overlying the substrate and underlying a protective coating having a high aluminum content. The diffusion barrier layer is characterized by having low interdiffusivity for elements from the substrate and the coating, a minimal impact on the mechanical properties of the article which is coated, and can be achieved readily using existing coating application techniques or post heat treat processes. The diffusion barrier layer is preferably an oxide ceramic.

  • Patent number: 6455173
    Abstract: A multilayered ceramic topcoat of a thermal barrier coating system is useful for high temperature corrosive applications such as hot section components in gas turbine engines. The ceramic topcoat includes at least two layers, each having generally columnar grain microstructures with different grain orientation directions. A preferred method of producing the multilayered ceramic topcoat includes positioning a superalloy substrate at a first angled orientation relative to a ceramic vapor cloud in an electron beam physical vapor deposition apparatus for a time sufficient to grow a first ceramic layer. The substrate is then reoriented to a second, different angled orientation for a time sufficient to grow a second ceramic layer. The ceramic layers exhibit columnar microstructures having respective grain orientation directions which are related to the first and second substrate orientations.

  • Patent number: 6451443
    Abstract: A corrosion-resistant coating for aluminum alloys preferably includes lithium molybdate and cerium. A conversion coating has been developed for aluminum surfaces that can substitute for the conventional chromate containing conversion coating. This new coating contains compounds such as lithium molybdate and cerium. The initial process consisted of two steps. Coated surface was tested to ASTM B117 requirement for 168 hours, showing little corrosion. Paint adhesion tests were also conducted with good results. Subsequent tests indicated that one step is adequate, but additional tests are needed.
