Patent number: 7939181Abstract: A PVD layer system for the coating of workpieces encompasses at least one mixed-crystal layer of a multi-oxide having the following composition: (Me11-xMe2x)2O3, where Me1 and Me2 each represent at least one of the elements Al, Cr, Fe, Li, Mg, Mn, Nb, Ti, Sb or V. The elements of Me1 and Me2 differ from one another. The crystal lattice of the mixed-crystal layer in the PVD layer system has a corundum structure which in an x-ray diffractometrically analyzed spectrum of the mixed-crystal layer is characterized by at least three of the lines associated with the corundum structure. Also disclosed is a vacuum coating method for producing a mixed-crystal layer of a multi-oxide, as well as correspondingly coated tools and components.Type: GrantFiled: October 11, 2006Date of Patent: May 10, 2011Assignee: Oerlikon Trading AG, TrubbachInventors: Jürgen Ramm, Beno Widrig, Michael Ante, Christian Wohlrab

Patent number: 7939180Abstract: A resin product (e.g., a millimeter-wave radar device cover) comprises a plate-like resin substrate, a base film formed on the resin substrate, and a metallic gloss film having a discontinuous structure formed on the base film, a top coat, a block coat, or the like being formed as a protective film on the metal film. The metal film contains a first film having a discontinuous structure obtainable by vacuum deposition of a first metal, a modified surface obtainable by modification of the surface of the first film by bringing the surface into contact with air, and a second film having a discontinuous structure obtainable by vacuum deposition of a second metal on the modified surface.Type: GrantFiled: November 21, 2006Date of Patent: May 10, 2011Assignee: Toyoda Gosei Co., Ltd.Inventors: Tetsuya Fujii, Chiharu Totani, Hiroshi Watarai, Takayasu Ido

Patent number: 7935428Abstract: The invention relates to a component made from a substrate with a coating, whereby that coating forms a surface of the component with reduced wettability. The invention further relates to production of said component. The coating which forms a surface with projections and recesses, brings about a reduction in wettability, in particular, by means of an effect based on the properties of lotus blossom. According to the invention, a metal with antimicrobial properties, in particular silver is provided under the coating, which is not fully covered, in other words, regions remain free of the coating in which the surface of the component is formed by the antimicrobial properties.Type: GrantFiled: January 31, 2006Date of Patent: May 3, 2011Assignee: Siemens AktiengesellschaftInventors: Christian Doye, Ursus Krüger, Manuela Schneider

Patent number: 7910219Abstract: A cermet armor material for highly effective ballistic performance which is comprised of a layer of base metal in which is deposited a layer or layers of ceramic and a compatible metal such that the deposited metal in combination with the base metal forms a continuous matrix around the ceramic particles. The body has a structure which is continuously graded from a highest ceramic content at the outer surface (strike face) decreasing to zero within the base substrate, and contained no abrupt interfaces.Type: GrantFiled: June 28, 2007Date of Patent: March 22, 2011Assignee: Materials & Electrochemical Research Corp.Inventors: James C. Withers, Roger S. Storm, Vladimir Shapovalov, Loutfy Raouf
