This disclosure provides systems and methods for improved electro-enhancement of surfaces of workpieces. The systems and methods can include immersing a metal workpiece in a salt bath and applying a time-varying electric current that has periods of high current with periods of lower current between. The systems and methods provide borided metal workpieces that contain preferred borides on the surface and lack less preferred borides. For example, the systems and methods can provide borided steel having Fe_(2)B and substantially lacking FeB on the surface.
