Abstract
A method of forming a textured surface layer along a substrate that includes disposing a plurality of polymer spheres on a surface of the metal substrate, and electroplating the metal substrate at a current density to deposit a metal layer along a body of each of the plurality of polymer spheres disposed on the surface of the metal substrate. The metal layer does not extend above a top surface of the plurality of polymer spheres. The method further includes removing the plurality of polymer spheres from the metal layer to form the textured surface defined by a size and shape of the plurality of polymer spheres.
