  • Coated hard alloy blade member
    Patent number: 6093479
    Abstract: A coated hard alloy blade member is disclosed which includes a substrate formed of a hard alloy of a WC-based cemented carbide or a TiCN-based cermet, and a hard coating deposited on the substrate. The hard coating includes an inner layer of TiCN having unilaterally grown crystals of an elongated shape and an outer layer of Al.sub.2 O.sub.3 having a crystal form .kappa. or .kappa.+.alpha. wherein .kappa.>.alpha.. The resulting blade member is highly resistant to wear and fracturing, and possesses cutting ability of a higher level.
    Type: Grant
    Filed: December 14, 1998
    Date of Patent: July 25, 2000
    Assignee: Mitsubishi Materials Corporation
