  • Publication number: 20110257054
    Abstract: The present disclosure describes compositions and a method for forming such compositions. More specifically, inorganic microparticles and surface modified silica nanoparticles are mixed to form a composition. The surface modified silica nanoparticles are present in the composition in an amount sufficient to decrease the coefficient of friction relative to a comparable composition that is free of surface modified silica nanoparticles.

  • Patent number: 7959891
    Abstract: The present invention provides a process for obtaining fullerene-like metal chalcogenide nanoparticles, comprising feeding a metal precursor selected from metal halide, metal carbonyl, organo-metallic compound and metal oxyhalide vapor into a reaction chamber towards a reaction zone to interact with a flow of at least one chalcogen material in gas phase, the temperature conditions in said reaction zone being such to enable the formation of the fullerene-like metal chalcogenide nanoparticles product. The present invention further provides novel IF metal chalcogenides nanoparticles with spherical shape and optionally having a very small or no hollow core exhibiting excellent tribological behaviour. The present invention further provides an apparatus for preparing various IF nanostructures.

  • Patent number: 7867330
    Abstract: The present invention relates to a metal treatment composition including Tin (II) Chloride and processed montmorillonite clay. The addition of Tin (II) Chloride to the composition provides Tin for forming a ceramic-metal layer on the surfaces of the friction pair. Tin (II) Chloride provides Chlorine ions for forming Chloric films for protecting juvenile surfaces which form in the friction zone. The clay is heated and pulverized to produce a powder comprising both particles having crystalline layer structure and salts and oxides. The layered crystalline structure of the clay contains slip planes that transversely shift when tangential pressure from the friction pair is applied thereby lubricating the friction pair. The salts and oxides contribute to the formation of the ceramic-metal layer.

  • Publication number: 20100263422
    Abstract: There is provided a lubricant for hot plastic working, which contains 20 to 40 mass % of iron oxide and 10 to 30 mass % of sodium silicate, wherein impurities are 3 mass % or less, and the lubricant contains 40 to 60 mass % of water. By virtue of combined action of these components, the lubricant exhibits excellent lubricity and suppliability and does not adversely affect the corrosion resistance of product. The lubricant is suitably used for lubricating a guide shoe in piercing-rolling, for example, a high-Cr steel and achieves a great effect of preventing a seizure flaw from occurring on the outer surface of product by being applied directly to the outer surface of a workpiece just before piercing rolling, preferably, within one second before starting piercing rolling.

  • Patent number: 7763573
    Abstract: The production of solid lubricant agglomerates by combining solid lubricant powder, an inorganic binder, other fillers if optionally desired, and a liquid to form a mixture, and driving off the liquid to form dry agglomerates which are subsequently classified by size or milled and classified by size to yield agglomerates of a desired size range. These agglomerates are then treated to stabilize the binder, thereby strengthening the binder and rendering it nondispersible in the liquid. The treated agglomerates are then blended or clad with a metal, metal alloy or a metallic composition, to produce a composition suitable for thermal spray applications.
