Abstract:
A method of treating a metallic surface of an article including the steps of providing an article having a metallic surface; texturizing the surface using a laser to create a controlled pattern across the surface; and anodizing the surface. The controlled pattern may include a series of pits etched in a predetermined repeating pattern across the surface, such as an array of dots or a grid. The controlled pattern may also include a series of pits etched in a predetermined pseudo-random pattern across the surface.
