Removing nickel plating from aluminum

Recently, nickel was plated onto a circular surface made of aluminum by means of Selectron Process. However, the surface has became rough and flaky. I'm looking for a way to remove the nickel plating without removing the aluminum, because the diameter of the circular surface is very critical.
