  • Coated cutting insert and method for making the same
    Patent number: 8668982
    Abstract: A coated cutting insert for removing material from a workpiece that includes a substrate is disclosed. A wear-resistant coating on the substrate that includes an alumina layer and a Zr- or Hf-carbonitride outer layer deposited on the alumina layer. The Zr- or Hf-carbonitride outer layer is subjected to a post-coat wet blasting treatment. The wet blasting changes the stress condition of the exposed alumina coating layer from an initial tensile stress condition to a compressive stress condition.
    Type: Grant
    Filed: November 18, 2011
    Date of Patent: March 11, 2014
    Assignee: Kennametal Inc.
    Inventors: Peter Leicht, Mark Greenfield, Volkmar Sottke, Zhigang Ban, Hartmut Westphal, Yixiong Liu, Michael Frank Beblo
  • Coated cutting insert and method for making the same
    Patent number: 8323783
    Abstract: A coated cutting insert for removing material from a workpiece that includes a substrate is disclosed. A wear-resistant coating on the substrate that includes an ?-alumina layer and a Zr— or Hf— carbonitride outer layer deposited on the ?-alumina layer. The Zr— or Hf— carbonitride outer layer is subjected to a post-coat wet blasting treatment. The wet blasting changes the stress condition of the exposed alumina coating layer from an initial tensile stress condition to a compressive stress condition.
