ABSTRACT:
This invention embodies the process and apparatus for applying a fluorocarbon coating or film to a metal or other material surface of a substrate, and particularly for applying such coating to the hull of a ship, or to other objects to be submerged in fresh or saltwater, to protect their surfaces from corrosion, and/or from fouling by marine organisms, and to improve the aqueous slip of a vessel during the period the object will be exposed to either aqueous, atmospheric, or other environments; and to protect virtually any substrate surface from virtually any environmental or man-made hazard. This process utilizes a laser that generates an infrared laser beam, such as, but not limited to a carbon derived gas type laser, to assist in the preparation for and attachment of a film or coating to a prepared substrate surface.
