  • Cutting insert having ceramic coating
    Patent number: 7887935
    Abstract: A cutting tool insert has a multilayer ceramic coating. The multilayer ceramic coating is a stratified structure of alternating sub layers of an oxide material and interfacial layers of a second material having good adhesion with the oxide material. The ceramic coating is deposited by chemical vapor deposition; each subsequently deposited interfacial layer serving to terminate a previously deposited oxide material sub layer and to serve as a surface for deposition of a subsequent oxide material sub layer. The second material is a solid solution of at least one element of the oxide material in a hard material.
    Type: Grant
    Filed: March 4, 2008
    Date of Patent: February 15, 2011
    Assignee: Iscar, Ltd.
