1. A method for electropolishing a manufactured metallic article, the method comprising:
contacting the metallic article with an electropolishing electrolyte; and
electropolishing the metallic article in the electropolishing electrolyte through the application of an applied current regime comprising:
at least two electropolishing regimes, each electropolishing regime comprising a current density of at least 2 A/cm2 and a voltage comprising a shaped waveform having a frequency from 2 Hz to 300 kHz, a minimum voltage of at least 0 V and a maximum voltage of between 0.5 to 500 V,
wherein at least one of: the frequency, current density, or maximum voltage of each electropolishing regime is changed compared to the preceding electropolishing regime.
