  • Patent number: 8921286
    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.

  • Patent number: 6913841
    Abstract: Liquid aluminum is sprayed onto an iron article to produce a thin tenacious non-corrodible layer. In one embodiment, an iron article is heated to at least 400° F. or preferably until cherry red. It is sprayed with a fine aluminum mist generated by heating aluminum in a container and then passing a gas under pressure through the container and out through a heat resistant ceramic nozzle. In another embodiment, aluminum is heated to at least 2000° F. in a container to produce a pool of liquid aluminum. Pressure is applied to the container to project the liquid aluminum in the form of a fine mist through a ceramic nozzle onto the iron article. The aluminum mist produces a tenacious aluminum layer on the iron article that is workable, weldable and non-corrodible. The aluminum layer is a permanent part of the iron article and cannot be removed by conventional means, such as buffing with a wire wheel driven by a electric motor.

  • Patent number: 6908663
    Abstract: A method and composition for providing a colored high performance wear surface for floor coverings is disclosed. Specifically, the floor covering includes a substrate and a high performance layer comprising a radiation cured pigmented composition. The exposed surface of the floor covering has a stain resistance of less than about 150 Delta E units. A pigmented high performance wear layer can be added in register with a printed design on the substrate or in register with an embossed texture of the substrate. Additionally, a high performance topcoat wear layer may be added. The pigmented high performance layer may include a nacreous pigment.

  • Patent number: 6890625
    Abstract: Surface covering components that include a topcoat layer with different gloss levels in various regions on the top coat layer, and methods of manufacturing such surface covering components, are disclosed. The surface covering components include a coating layer that includes regions that have a relatively higher gloss, and regions with a relatively lower gloss. The differential gloss is provided by coating a substrate with a UV-curable coating composition, subjecting a first region of the surface coating to polymerization under a first set of conditions, and subjecting a second region of the surface coating to polymerization under a second set of conditions. The UV-curable coating compositions include UV-curable components and one or more flatting agents. The different polymerization conditions involve applying various photoinitiators, thermal initiators and/or cure altering agents to some regions of the coated substrate, and not applying these components to other regions of the substrate.

  • Patent number: 6881498
    Abstract: A surface processing method and power transmission component includes refining a surface region of a metal from a first roughness to a second roughness less than the first roughness. A solid lubricous coating or a hard coating is then deposited on the surface region. The metal has a surface hardness above 50 Rc to reduce the risk that the metal will deform under the coating and leave the coating unsupported. The surface region of the metal may be transformed into a nitrogen-containing compound or solid solution surface region before the surface refining step and deposition of the coating.

  • Patent number: 6869684
    Abstract: In a method of providing a surface with a protection layer having at least a first surface area (2) and a second surface area (1), which surface areas (1, 2) are distinguishable in that the surface areas (1, 2) differ from each other in at least one visual property, parts of the surface situated outside the first surface area (2) are masked with a mask layer which partially covers the surface, and the surface is subjected to an electrochemical treatment (14, 20), whereby non-masked parts of the surface are treated. As the mask layer provided on the surface is a sol-gel layer forming the protection layer in the second surface area (1), a wear-resistant surface-protection layer having visually distinguishable surface areas is provided in an efficient manner. An object which can be obtained by means of the proposed method is also described.

    Abstract: A body such as a cutting tool coated with refractory single- or multilayers, wherein specific layers are characterized by a controlled microstructure and phase composition with crystal planes preferably grown in a preferential direction with respect to the surface of the coated body. The coating includes one or several refractory layers of which at least one layer is a dense, fine-grained layer of ?-Al2O3 preferably textured in the (104) direction. The coated tool exhibits excellent surface finish and shows much improved wear and toughness properties compared to prior art objects when used for machining steel, cast iron and, particularly, when machining nodular cast iron.
