Remove Cu+Ni Plating From Mild Steel

We have some Mild Steel precision components Cu+Ni Plated. The plating is not uniform and we need to get it replated. We tried replating the plated piece and failed since we are observing peel offs from the surface. I need to know if there is a process to remove the Cu+Ni plating and then do replating to attain uniformity across the surface.

The chrome must be removed in any case, but if the original nickel plating has good adhesion, it may be more economical and environmentally responsible to activate it properly (if possible) and plate on top of it. If it has poor adhesion or is impossible to activate, you must strip the nickel. Proprietary nickel strippers are often the way to go.
