  • Method and apparatus for providing a conductive, amorphous non-stick coating
    Patent number: 6270831
    Abstract: A conductive, non-stick coating is provided using a ceramic material which is conductive, flexible and provides a surface which exhibits the property of lubricity. A room or near room temperature manufacturing process produces a coating of titanium nitride on a substrate, where the coating is amorphous if the substrate is a solid material including plastics, composites, metals, magnets, and ceramics, enabling the substrate to bend without damaging the coating. The coating can also be applied as a conformal coating on a variety of substrate shapes, depending upon the application. The coating is bio-compatible and can be applied to a variety of medical devices.
    Type: Grant
    Filed: April 30, 1998
    Date of Patent: August 7, 2001
    Assignees: MedQuest Products, Inc., University of Utah Research Foundation
