ABSTRACT:
A metallic coating is applied to a metallic substrate by directing a laser beam on to the substrate and simultaneously directing a gas stream containing entrained particles of the coating material on to the area of laser impingement on the substrate. The particles are melted by the laser beam to form a pool of molten coating metal. Relative movement is effected between the laser beam and substrate so that a pool of molten coating metal traverses the substrate to form a solidified metallic coating which is fused to the metallic substrate.
