A method of applying a laser metal formed build layer on a surface (16) of an article (12) is disclosed. A laser deposition head (10) including a light source (17) and a nozzle (18) is positioned relative to the surface of the article by a distance that is about normal to the surface. The surface (16) of the article is melted locally using the laser light source to form a melt pool (26). Powdered metal (30) is injected into the melt pool (26) using the nozzle (18). The melt pool (26) is solidified to form the build layer (36F) having a desired microstructure on the surface (16) of the article (12). |
