Title (EN) A METHOD AND APPARATUS FOR APPLYING A COATING ON A SUBSTRATE
(FR) PROCÉDÉ ET APPAREIL POUR APPLIQUER UN REVÊTEMENT SUR UN SUBSTRAT
Abstract:
(EN) The present invention is related to a method for applying a coating (4) on a substrate (1), comprising the steps of: - scanning a laser beam (2) along a line on the surface of said substrate, - supplying a coating forming material from a supply system (3), said system moving along the same line as the laser beam but coming up behind the laser beam, so that the coating forming material is deposited on a spot which has previously been heated by the laser beam to a temperature above the melting temperature of the coating forming material, wherein substantially no physical contact occurs between the laser beam and the coating forming material. Preferably, the method further comprises a second step of scanning the surface a second time with said laser beam, without adding coating forming material during the second step.
(FR) La présente invention concerne un procédé pour appliquer un revêtement (4) sur un substrat (1), comprenant les étapes consistant à : - balayer un faisceau laser (2) le long d’une ligne sur la surface dudit substrat, - fournir un matériau formant revêtement à partir d’un système d’alimentation (3), ledit système se déplaçant le long de la même ligne que le faisceau laser, mais se trouvant derrière le faisceau laser, de sorte que le matériau formant revêtement est déposé sur un point qui a été précédemment chauffé par le faisceau laser à une température au-dessus de la température de fusion du matériau formant revêtement, sensiblement aucun contact physique ne se produisant entre le faisceau laser et le matériau formant revêtement. De préférence, le procédé comprend en outre une seconde étape consistant à balayer la surface une seconde fois avec ledit faisceau laser, sans ajouter de matériau formant revêtement lors de la seconde étape.
