  • Coated cutting tool
    Patent number: 12390861
    Abstract: The present invention relates to a coated cutting tool including a Cr-containing cemented carbide substrate having WC, a binder phase and a gamma phase. The cemented carbide includes a gradient surface zone with a thickness of between 2 to 100 ?m, which is binder phase enriched and depleted of gamma phase. The cemented carbide includes M7C3 carbides in an amount of between 0.5 to 7 area % measured in the bulk, where M is elements being Cr, W and at least one binder metal. The coated cutting inserts shows an improved edge line toughness.
    Type: Grant

    Date of Patent: August 19, 2025
    Assignee: AB Sandvik Coromant
    Inventors: Susanne Norgren, Bartek Kaplan
  • Cemented carbide with alternative binder
    Patent number: 11850663
    Abstract: A cemented carbide including an eta phase and a Ni—Al binder is provided. The Ni—Al binder includes intermetallic y?-Ni3Al -precipitates embedded in a substitutional solid solution matrix of Al and Ni. A weight ratio Al/Ni of between 0.03 to 0.10, wherein a total amount of Ni and Al is between 70 to 95 wt % of the total binder A method of making a cutting tool is also provided.
