Publication number: 20140061034Abstract: The invention relates to a method for coating work pieces in a vacuum treatment system having a first electrode embodied as a target, which is part of an arc vaporization source. Using the first electrode, an arc is operated with an arc current and vaporizes material. A bias voltage is applied to a bias electrode, which includes a second electrode that is embodied as a work piece holder, together with the work pieces. Metal ion bombardment is carried out either to pretreat the work pieces or in at least one transition from one layer to an adjacent layer of a multilayer system, so that neither a significant material removal nor a significant material buildup occurs, but instead, introduces metal ions into a substrate surface or into a layer of a multilayer system.Type: ApplicationFiled: November 8, 2013Publication date: March 6, 2014Applicant: Oerlikon Trading AG, TrübbachInventors: Helmut Rudigier, Jürgen Ramm, Beno Widrig, Troy Vom Braucke

Publication number: 20140061030Abstract: The invention relates to a magnetron sputtering process that allows material to be sputtered from a target surface in such a way that a high percentage of the sputtered material is provided in the form of ions. According to the invention, said aim is achieved using a simple generator, the power of which is fed to multiple magnetron sputtering sources spread out over several time intervals, i.e. the maximum power is supplied to one sputtering source during one time interval, and the maximum power is supplied to the following sputtering source in the subsequent time interval, such that discharge current densities of more than 0.2 A/cm2 are obtained. The sputtering target can cool down during the off time, thus preventing the temperature limit from being exceeded.Type: ApplicationFiled: March 30, 2012Publication date: March 6, 2014Applicant: OERLIKON TRADING AG, TRUBBACHInventors: Siegfried Krassnitzer, Kurt Ruhm

Publication number: 20140054165Abstract: The invention relates to a method for operating a pulsed discontinuous spark discharge. The spark is fed via a capacitor. Between the pulses there are switched-off time intervals during which no spark current flows. Within the pulses, that is to say during the switched-on time intervals, the supply of charge is stopped upon a current threshold being reached and is restarted, with the result that subpulses occur within the pulses. The time intervals and subpulses are chosen according to the invention such that when the capacitor is switched on again, the spark discharge readily ignites again.Type: ApplicationFiled: March 26, 2012Publication date: February 27, 2014Applicant: OERLIKON TRADING AG, TRUBBACHInventors: Jürgen Ramm, Beno Widrig, Kurt Ruhm

Publication number: 20140048209Abstract: The present invention relates to an ignition device for igniting a high-current discharge of an electrical arc evaporator in a vacuum coating system. Ignition is performed by means of mechanically closing and opening a contact between the cathode and the anode. Contact is established by means of an ignition finger that can move on a forced path. On account of the forced path, the ignition finger can be moved by means of a simple mechanical drive to a park position, which is protected against coating, and said ignition finger can also be used to ignite a second target.Type: ApplicationFiled: August 9, 2013Publication date: February 20, 2014Applicant: OERLIKON TRADING AG, TRUBBACHInventors: Siegfried Krassnitzer, Oliver Gstoehl, Juerg Hagmann

Publication number: 20130344256Abstract: The present invention relates to a method for effective spark detection during a process for treating workpieces with a vacuum treatment installation, For this purpose, in the case of a bias voltage applied to the workpieces, the discrepancy between the current flowing through the workpieces and a mean value is measured and, in the event of a threshold value being exceeded by this discrepancy, the process is stopped.

Patent number: 8541105Abstract: This invention concerns a method of producing subsurface marking in a transparent body. According to the invention, the marking is done less than 500 ?m below the surface by applying a layer system with a high destruction threshold, compared to the substrate, to the surface of the substrate. If the layer system is designed as an anti-reflection coating system for the reading wavelength, it increases the contrast for reading. If the layer system is designed as a mirror for the writing wavelength, the writing can be done in reflection at a lower intensity.Type: GrantFiled: August 18, 2006Date of Patent: September 24, 2013Assignee: Oerlikon Trading AG, TrubbachInventors: Philipp Smole, Michael Lanker, Claus Heine-Kempkens

Publication number: 20130240373Abstract: The invention relates to a process for electrochemically removing a coating from coated workpieces by means of a voltage applied in an electrolyte bath between the workpiece and a counter-electrode. According to the invention, a rising voltage profile is selected during the coating removal process. This has the effect that the voltage applied at the start is low, and therefore the workpieces are not damaged, but nevertheless the rise in the voltage prevents the coating removal process taking an uneconomically long time.Type: ApplicationFiled: September 22, 2011Publication date: September 19, 2013Applicant: OERLIKON TRADING AG, TRUBBACHInventors: Mirco Elias Kostner, Udo Rauch
