Adhesion of Ni to Ti Substrate


I'm looking to plate nickel onto titanium parts that are very sensitive dimensionally speaking (satellite applications). At the same time I'm concerned about the etching and pickling procedures that some literature calls for, as far as being too aggressive. What can I do to avoid dimensional instability (i.e., actual loss of substrate) while making sure that we have adhesion of the nickel finish to the part? Also to be considered is the complex geometry of the part in question.

Thanx in advance,

ASM Metals Handbook Vol. 5, "Surface Engineering" has a great chapter on preparing titanium and refractory metals for plating, Florin. Good luck.
