Pretreatment of Elgiloy Wire for Nickel Plating

I am seeking pretreatment cycles to allow nickel electroplating on elgiloy wire. I have tried various versions of Wood's strikes, but the adhesion is not consistent.

Elgiloy Co 39-41 Cr 19-21 Ni 14-16 Mo 6-8 Chromium is very soluble in hydrochloric acid, so you might be eating away at the alloy as fast as you are laying down a thin layer of nickel in that strike. I would try less acid, or change to a low pH Watts or nickel sulphate strike.
