Patent number: 11535928Abstract: A method for coating substrates in an arc vaporization source for generating hard surface coatings on tools is provided. The method includes providing an arc-vaporization source with at least one electric solenoid and a permanent magnet arrangement including marginal permanent magnets and a central permanent magnet. The method further includes adjusting the position of the central and marginal permanent magnets relative to the target surface in at least three settings, adjusting the strength of the generated magnetic field based on the position of the central and marginal permanent magnets among the at least three settings, and coating the substrates by an ARC vaporization coating process performed by the ARC vaporization source at each of the at least three settings.Type: GrantFiled: February 5, 2020Date of Patent: December 27, 2022Assignee: OERLIKON SURFACE SOLUTIONS AG, PFÄFFIKONInventors: Siegfried Krassnitzer, Juerg Hagmann, Oliver Gstoehl

Patent number: 11264216Abstract: The present invention relates to an arc vaporization source for generating hard surface coatings on tools. The invention comprises an arc-vaporization source, comprising at least one electric solenoid and a permanent magnet arrangement that is displaceable relative to the target surface. The vaporization source can be adjusted to the different requirements of oxide, nitride, or metal coatings. The rate drop during the lifespan of a target to be vaporized can be held constant or adjusted by suitably adjusting the distance of the permanent magnets to the front side of the target. A compromise between the coating roughness and rate can be set.Type: GrantFiled: December 30, 2009Date of Patent: March 1, 2022Assignee: OERLIKON SURFACE SOLUTIONS AG, PFÄFFIKONInventors: Siegfried Krassnitzer, Juerg Hagmann, Oliver Gstoehl

Patent number: 9997338Abstract: This invention relates to an arc-based method for the deposition of insulating layers and to an arc-based method for low-temperature coating processes, in which an electric arc discharge, ignited and applied on the surface of a target in an arc source, is simultaneously fed a direct current and a pulsed or alternating current. The invention further relates to an arc source in which the target is connected to a power supply unit that encompasses either a minimum of one pulsed high-current power supply 18, 18? and an additional power supply 13?, 18?, or a power supply 21, 21?, 22 designed with switchable combinatorial circuitry.Type: GrantFiled: April 8, 2005Date of Patent: June 12, 2018Assignee: OERLIKON SURFACE SOLUTIONS AG, PFÄFFIKONInventors: Jürgen Ramm, Oliver Gstoehl, Beno Widrig, Daniel Lendi

Patent number: 9601316Abstract: 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: GrantFiled: August 9, 2013Date of Patent: March 21, 2017Assignee: OERLIKON SURFACE SOLUTIONS AG, PFAFFIKONInventors: Siegfried Krassnitzer, Oliver Gstoehl, Juerg Hagmann

Publication number: 20160109306Abstract: A force measuring device including a crystalline layer with piezoelectric properties. The layer is arranged on at least part of a surface of a solid state actuator (or carrier). The device also includes at least one wear-protection layer with anti-frictional properties. The piezoelectric layer includes crystalline aluminium nitride having a hexagonal crystal structure with a pronounced crystal orientation (002), at least one electrically conductive layer being applied between the surface of the solid-state actuator and the crystalline aluminium nitride layer. The conductive layer is preferably a metal layer consisting of at least one metal, which when oxidized, forms an electrically insulating oxide that is mechanically and thermally more stable than molybdenum(VI) oxide (Mo03).Type: ApplicationFiled: October 22, 2013Publication date: April 21, 2016Applicant: Oerlikon Surface Solutions AG, TrubbachInventors: Albert Peter Gerhard Janssen, Oliver Gstoehl

Patent number: 8864959Abstract: Planetary carriers (22) for workpieces mounted on a carousel (19) are provided within a vacuum chamber. A source (24) for a cloud comprising ions (CL) is provided so that a central axis (ACL) of the cloud intercepts the rotary axis (A20) of the carousel (19). The cloud (CL) has an ion density profile at the moving path (T) of planetary axes (A22) which drops to 50% of the maximum ion density at a distance from the addressed center axis (ACL) which is at most half the diameter of the planetary carriers (22). When workpieces upon the planetary carriers (22) are etched by the cloud comprising ions material which is etched off is substantially not redeposited on neighboring planetary carriers but rather ejected towards the wall of the vacuum chamber.Type: GrantFiled: April 21, 2009Date of Patent: October 21, 2014Assignee: Oerlikon Trading AG, TruebbachInventors: Siegfried Krassnitzer, Oliver Gstoehl, Markus Esselbach
