Title (EN) LASER COATING PROCESS
(FR) PROCEDE DE REVETEMENT AU LASER
Abstract:
(EN) This invention embodies the process and apparatus for applying a fluorocarbon coating or film to a metal or other material surface of a substrate (S), and particularly for applying such coating (C2) 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 (S) from virtually any environmental or man-made hazard. This process utilizes a laser (7) that generates an infrared laser beam (L) 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 (C2) to a prepared substrate surface (S).
(FR) L'invention se rapporte à un procédé et à un appareil servant à appliquer un revêtement ou un film au fluorocarbone sur une surface de métal ou d'un autre matériau d'un substrat (S) et servant plus particulièrement à appliquer un tel revêtement (C2) sur la coque d'un bateau ou sur tout autre objet devant être immergé dans de l'eau douce ou de l'eau salée afin de protéger leur surface de la corrosion et/ou du fouling créés par les microorganismes marins de façon à améliorer le glissement dans l'eau du bateau pendant la période où l'objet est exposé aux agents aqueux, aux agents atmosphériques ou aux autres agents ambiants, et afin de protéger virtuellement toute surface de substrat (S) de tout danger ambiant ou créé par l'homme. Ce procédé utilise un laser (7) produisant un rayon laser à infrarouges (L), tels qu'un laser de type à gaz dérivé du carbone, destiné à faciliter la préparation d'un film ou d'un revêtement (C2) et sa fixation sur une surface de substrat préparé (S).
