  • Coated extrusion tool
    Patent number: 10675665
    Abstract: Provided are extrusion tools such as extrusion dies or portions thereof having a surface with at least one coating thereon, and methods of forming the same are disclosed. The at least one coating is formed from a composition that is a metal aluminum nitride or carbonitride with particular characteristics such that the amount of aluminum varies within the coating between a coating outer surface and an intermediate thickness within the coating. The resulting coatings have tailored physical and performance characteristics that result in improved wear and extrusion performance.
    Type: Grant
    Filed: December 7, 2016
    Date of Patent: June 9, 2020
    Assignee: IHI Ionbond AG.
    Inventors: Michael Auger, Hristo Strakov, Vasileios Papageorgiou, Stylianos Vogiatzis, Val Lieberman

  • Chemical vapor deposition reactor for depositing layers made of a reaction gas mixture onto workpieces
    Patent number: 9297070
    Abstract: The invention relates to a CVD-reactor for depositing layers made of a reaction gas onto workpieces. Said reactor comprises an elongate, vertical reaction chamber that is defined by a reactor wall and a reactor base, an inlet line for guiding the reaction gas into the reaction chamber, entering into the region of the reactor base in the reaction chamber, a central outlet line that guides the used reaction gas out of the reaction chamber and that extends out of the reactor chamber in the region of the reactor base, a tier-like workpiece receiving element that is arranged in a central manner in the reaction chamber and can be rotated about the central axis thereof.

  • Coated cutting tool, cutting member or wear part
    Patent number: 8703245
    Abstract: A coated metal substrate has at least one layer of titanium based hard material alloyed with at least one alloying element selected from the list of chromium, vanadium and silicon. The total quantity of alloying elements is between 1% and 50% of the metal content, the layer having a general formula of: (Ti100-a-b-cCraVbSic)CxNyOz.
