  • Multilayer nitride hard coatings
    Patent number: 11453063
    Abstract: In one aspect, coatings are described herein employing composite architectures providing high aluminum content and high hardness for various cutting applications. For example, a coated cutting tool comprises a substrate and a coating comprising a refractory layer deposited by physical vapor deposition adhered to the substrate, the refractory layer comprising a plurality of sublayer groups, a sublayer group comprising a titanium aluminum nitride sublayer and an adjacent composite sublayer comprising alternating nanolayers of titanium silicon nitride and titanium aluminum nitride.
    Type: Grant
    Filed: February 6, 2020
    Date of Patent: September 27, 2022
    Assignee: KENNAMETAL INC.
    Inventors: Vineet Kumar, Ronald Penich, Chen Chen, Zhenyu Liu, Nicholas F. Waggle, Jr.
