Method and apparatus for providing a conductive, amorphous non-stick coating
TLDR
In this paper, a conductive, non-stick coating (62) is provided using a ceramic material which is conductive and flexible and provides a surface which exhibits the property of lubricity.Abstract:
A conductive, non-stick coating (62) 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 biocompatible and can be applied to a variety of medical devices.read more
