Patent number: 9434003Abstract: A molding is produced with a disk-shaped or plate-shaped basic body having a large number of knob-like and/or web-like elevations which merge into the basic body with inclined side surfaces. The molding is produced by pressing and sintering powdery raw materials close to the final shape. First, the boundary surfaces of the basic body are pressed to final shape as far as the transition regions of the elevations and the elevations are pressed to an oversize. The projection height of the elevations from the basic body is greater than the projection height in the finally pressed state. Their side surfaces form an angle of inclination in the range from 90°-150° with the respectively adjacent boundary surface of the basic body. Then the elevations are pressed to near final shape while the angle of inclination is enlarged to a greater value.Type: GrantFiled: March 30, 2012Date of Patent: September 6, 2016Assignee: Plansee SEInventors: Gebhard Zobl, Wolfgang Glatz, Wolfgang Kraussler, Robert Oberbreyer

Patent number: 9269525Abstract: A high-temperature-resistant composite body is formed by joining over an area of a first, nonmetallic section via a bonding solder layer to a second, metallic section composed of Mo, an Mo-based alloy, W or a W-based alloy. A first arrangement composed of the first section, a first Zr solder and an intermediate layer is firstly soldered together in a first soldering step. A second arrangement of the resulting partial composite body, a second solder adjoining the intermediate layer and the second section is subsequently soldered together in a second soldering step. The intermediate layer at least 90 atom % of at least one of the elements Ta, Nb, W. The second solder is formed by precisely one material selected from Ti, Ti-based solder combination, V-based solder combination, Zr or Zr-based solder combination and it melts at a lower temperature than the first Zr solder in the second arrangement.Type: GrantFiled: November 22, 2012Date of Patent: February 23, 2016Assignee: Plansee SEInventors: Thomas Mueller, Klaus Ennemoser, Wolfgang Glatz, Andreas Menhard

Patent number: 9031202Abstract: A rotary anode for a rotary anode X-ray tube has an anode disc with a supporting portion. A focal track is located in the vicinity of an outer diameter of the anode disc. The supporting portion has inhomogeneous material properties along a radial coordinate of the anode disc to provide a high mechanical load capacity in the area of an inner diameter of the anode disc and a high thermal load capacity at the focal track. These measures provide for a rotary anode for a rotary anode X-ray tube that meets the extreme thermal and mechanical loads during operation. Further, a method for manufacturing such a rotary anode is described as well.Type: GrantFiled: August 10, 2010Date of Patent: May 12, 2015Assignee: Plansee SEInventors: Ulrich Hove, Zoryana Terletska, Christoph Bathe, Peter Rödhammer, Jürgen Schatte, Wolfgang Glatz, Thomas Müller

Patent number: 8243884Abstract: An X-ray anode includes a coating and a support body. In addition to a strength-imparting region, the support body has a region formed of a diamond-metal composite material. The diamond-metal composite material is formed of 40 to 90% by volume diamond particles, 10 to 60% by volume binding phase(s) formed of a metal or an alloy of the metals of the group consisting of Cu, Ag, Al and at least one carbide of the elements of the group consisting of Tr, Zr, Hf, V, Nb, Ta, Cr, Mo, W, B, and Si. The highly heat-conductive region can be form-lockingly connected at the back to a heat-dissipating region, for example formed of Cu or a Cu alloy. The X-ray anode has improved heat dissipation and lower composite stress.Type: GrantFiled: September 25, 2008Date of Patent: August 14, 2012Assignee: Plansee SEInventors: Peter Rödhammer, Wolfgang Glatz, Bernhard Tabernig, Hannes Wagner

Patent number: 8173063Abstract: The invention relates to a process for producing a molding, comprising a disk-like or plate-like basic body -5- having a large number of knob-like and/or web-like elevations -4-3- which merge into the basic body -5- with inclined side surfaces, by means of pressing and sintering powdery raw materials close to the final shape. According to the invention, the pressing is carried out in a two-stage pressing operation. In the first stage the boundary surfaces of the basic body -5- are pressed to at least the approximate final shape as far as the transition regions of the elevations -3-4- and, at the same time, the elevations -3-4- are pressed to an oversize. The projection h? of the elevations -3-4- from the basic body -5- is greater by 10%-150% as compared with the projection h from the basic body -5- in the finally pressed state. Their side surfaces form an angle of inclination ?? in the range from 90°-150° with the respectively adjacent boundary surface of the basic body -5-.Type: GrantFiled: July 30, 2003Date of Patent: May 8, 2012Assignee: Plansee SEInventors: Gebhard Zobl, Wolfgang Glatz, Wolfgang Kraussler, Robert Oberbreyer
