  • Coated cutting tools
    Patent number: 5395680
    Abstract: Provided is a coated cutting tool having a coating and a substrate. The coating includes at least one CVD layer which may have a residual tensile stress and at least one layer having a high residual compressive stress. The outermost layer of the coating is preferably the one containing residual compressive stresses. The substrate is a composite having hard refractory grains.
    Type: Grant
    Filed: July 2, 1993
    Date of Patent: March 7, 1995
    Assignee: Kennametal Inc.

  • CVD and PVD coated cutting tools
    Patent number: 5364209
    Abstract: Provided is a coated cutting tool having a coating and a substrate. The coating includes at least one chemical vapor deposited (CVD) layer and at least one physical vapor deposited (PVD) layer. The outermost layer of the coating is a PVD layer, containing residual compressive stresses. The substrate is a composite having hard refractory grains bonded together by a binder material.

  • Method of machining using coated cutting tools
    Patent number: 5325747
    Abstract: Provided is a coated cutting tool having a coating and a substrate. The coating includes at least one CVD layer which may have a residual tensile stress and at least one layer having a high residual compressive stress. The outermost layer of the coating is preferably the one containing residual compressive stresses. The substrate is a composite having hard refractory grains. The cutting tool has been found to be particularly useful in the machining of titanium alloys and superalloys.

  • Coated cutting insert
    Patent number: 5188489
    Abstract: A coated indexable cutting insert for wet and dry milling of cast irons is provided. The substrate of the insert is composed of a cemented tungsten carbide based composition containing about 5.7 to about 6.4 weight percent cobalt and about 2.9 to about 3.6 weight percent tantalum. The coating includes two coatings of differing composition. The first coating is selected from titanium carbide, titanium carbonitride, and titanium nitride. The second coating is alumina.
