A method for applying a coating ( 4 ) on a substrate ( 1 ), includes: -scanning a laser beam ( 2 ) along a line on the surface of said substrate. The method also includes supplying a coating forming material from a supply system ( 3 ), the 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. Substantially no physical contact occurs between the laser beam and the coating forming material. Preferably, the method further includes a second step of scanning the surface a second time with the laser beam, without adding coating forming material during the second step. |
