    Abstract: Method for producing an aluminum foil with integrated security features. An aluminum foil is rolled down to a thickness of less than 150 ?m in a plurality of cold rolling passes, texturing that runs in the direction of rolling being induced simultaneously on both surface sides of the foil. In a final cold rolling pass, the foil is fed to a working roller pair, in which, on at least one roller surface, the relief-like surface structuring generated in the rolling direction by grinding was reduced on the basis of contrast and motif in a region of 10 to 50% relative to the average surface roughness to form a motif for a security feature that is transferred to the surface side of the foil facing the roller surface. The generated aluminum foil has a glossy appearance on both sides such that the security feature rises clearly due to its dull appearance.

  • Patent number: 8920938
    Abstract: With the invention a metallic flat product can be systematically made available with such a fine, stochastic or quasi-stochastic surface texture that after a typical automotive paint application it is only minimally perceptible, if at all, by the human eye. At the same time, in the case of a surface topography constituted according to the invention, the transition between the peak plateaus and the valleys takes place via steep flanks. In this way, it is achieved that the morphology of the sheet metal surface is practically independent of the actual depth of the valleys. As a result therefore, the morphology of the sheet metal surface of a metallic flat product according to the invention is also independent of the skin-pass rate, which is obtained when the fine metal texture is produced by skin-pass rolling.

  • Patent number: 8906733
    Abstract: A method for creating a nanostructure according to one embodiment includes depositing material in a template for forming an array of nanocables; removing only a portion of the template such that the template forms an insulating layer between the nanocables; and forming at least one layer over the nanocables. A nanostructure according to one embodiment includes a nanocable having a roughened outer surface and a solid core. A nanostructure according to one embodiment includes an array of nanocables each having a roughened outer surface and a solid core, the roughened outer surface including reflective cavities; and at least one layer formed over the roughened outer surfaces of the nanocables, the at least one layer creating a photovoltaically active p-n junction. Additional systems and methods are also presented.

  • Publication number: 20140356578
    Abstract: A method for producing a metal or metal alloy surface or metal oxide layer or metal alloy oxide layer on the surface of a workpiece having surface structures with dimensions in the sub-micrometer range, involves scanning the entire surface of the metal or of the metal alloy or of the metal or metal alloy oxide layer on the metal or the metal alloy on which the structures are to be produced and which are accessible to laser radiation one or more times by a pulsed laser beam in such a way that adjacent flecks of light of the laser beam adjoin one another without gaps or overlap one another and a specific region of a predetermined relation between method parameters is satisfied.

  • Publication number: 20140349137
    Abstract: A method for producing a chemically modified metal surface or metal alloy surface or metal oxide layer or metal alloy oxide layer on the surface of a workpiece, which surface or layer includes surface structures having dimensions in the sub-micrometer range. The method involves scanning, one or several times using a pulsed laser beam, the entire surface of the metal or metal alloy, or the metal oxide layer or metal alloy oxide layer on the metal or metal alloy, on which surface or layer the structures are to be produced and which is accessible to laser radiation. The scanning is performed in an atmosphere containing a gas or gas mixture that reacts with the surface, such that adjacent flecks of light of the laser beam adjoin each other without an interspace in between or overlap and a predetermined range of a defined relation between process parameters is satisfied.
