Abstract
A method for surface roughening a metal work piece includes disposing a region of the workpiece to be roughened proximate to a counter electrode. The region of the workpiece to be roughened and the counter electrode are subsequently disposed together in an electrolyte. An electric potential with current flow is applied between the work piece and the counter electrode to roughen the metal surface to a desired roughness.
