Patent number: 7713638Abstract: The invention relates to layer systems having at least one layer comprising titanium aluminum oxide. The layer comprising titanium aluminum oxide may be either a functional layer—with or without interruption by an intermediate layer which is optically inactive—or a functional layer formed from a metal oxide which is interrupted by an intermediate layer comprising titanium aluminum oxide. The layer systems are structurally and thermally stable at operating temperatures of over 600° C. The layer systems may either comprise only one functional layer or may be a multilayer system, preferably an alternating layer system composed of functional layers with high and low refractive indices.Type: GrantFiled: September 13, 2003Date of Patent: May 11, 2010Assignee: Schott AGInventors: Christoph Moelle, Lars Bewig, Frank Koppe, Thomas Kuepper, Stefan Geisler, Stefan Bauer, Juergen Dzick, Christian Henn

Patent number: 7641773Abstract: A method of producing substrates with functional layers which have high optical properties and/or a high surface smoothness, in particular a low turbidity and significantly lower roughness, is provided. The method includes a sputtering process for coating a substrate with at least one functional layer, the sputtering process being interrupted at least once by the application of an intermediate layer with a thickness of less than 20 nm.Type: GrantFiled: September 13, 2003Date of Patent: January 5, 2010Assignee: Schott AGInventors: Christoph Moelle, Lars Bewig, Frank Koppe, Thomas Kuepper, Stefan Geisler, Stefan Bauer

Patent number: 7381469Abstract: The invention relates to a coated object in which coatings remain of a constant and unchanged high quality despite operating temperatures of more than 350° C. This is achieved with interlayers which deliberately interrupt and thereby stabilize the morphology of the coating.Type: GrantFiled: April 21, 2004Date of Patent: June 3, 2008Assignee: Schott AGInventors: Christoph Moelle, Lars Bewig, Frank Koppe, Thomas Küpper, Stefan Geisler, Stefan Bauer, Jürgen Dzick

Publication number: 20060127699Abstract: A scratchproof, temperature-stable protective layer, in particular a scratch-resistant protective layer for cooking hobs is provided. In addition, processes and an apparatus for producing these protective layers are provided. The protective layer includes at least one hard-material layer having a functional layer interrupted by very thin interlayers so that the functional layer has a morphologically dense columnar structure that grows substantially perpendicular to the body surface. The production of layers of this type is achieved by a magnetron sputtering process and a corresponding arrangement, with the tendency of the columnar structures to widen out being reduced by targeted interruption of the growth of the functional layers.Type: ApplicationFiled: September 13, 2003Publication date: June 15, 2006Inventors: Christoph Moelle, Lars Bewig, Frank Koppe, Thomas Kupper, Stefan Geisler, Stefan Bauer, Juergen Dzick, Lutz Klippe, Christian Henn
