Patents by Inventor Charles Erik Bauer

Charles Erik Bauer has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Diamond coated cutting tool and method for making the same
    Patent number: 6890655
    Abstract: A diamond coated cutting tool that has a treated substrate and a diamond coating thereon. In the process of making the substrate, the sintered substrate is re-sintered to form a re-sintered substrate and the re-sintered substrate is chemically treated to remove cobalt on the surface of the re-sintered substrate as to form a treated substrate.
    Type: Grant
    Filed: August 6, 2003
    Date of Patent: May 10, 2005
    Assignee: Kennametal Inc.
    Inventors: Yixiong Liu, Joseph M. Tauber, Charles Erik Bauer

  • Method for making diamond coated cutting tool
    Patent number: 6660329
    Abstract: A process for making a diamond coated cutting tool that comprises the steps of providing a sintered substrate, re-sintering the sintered substrate to form a re-sintered substrate, subjecting the re-sintered substrate to a chemical treatment to remove cobalt on the surface of the re-sintered substrate so as to form a treated substrate, and adherently depositing a diamond coating to the treated substrate.

  • Diamond coated tools and process for making
    Patent number: 6287682
    Abstract: A process for making a diamond-coated tool and the tool made thereby. The process includes a sintering step. In that step, the tool substrate is sintered in an atmosphere and for a time and at a temperature so that superficial, exaggerated grain growth is promoted that imparts a surface roughness which may serve as anchoring sites during a subsequent diamond coating step which is performed by a vapor deposition technique. The diamond-coated tool prepared by the process includes a large grain substrate surface, and an high bond strength between the diamond coating and the substrate surface.

  • Process for making diamond coated tools and wear parts
    Patent number: 5648119
    Abstract: A diamond-coated tool and a process for making them. The process includes a sintering step. In that step, a substrate is sintered in an atmosphere and for a time and at a temperature so that superficial, exaggerated grain growth is promoted that imparts a surface roughness which may serve as anchoring sites during a subsequent diamond coating step which is performed by a vapor deposition technique. The diamond-coated tool or wear part includes a large grain substrate surface, and a high bond strength between the diamond coating and the substrate surface.
