One of our readers had a suggestion for getting a stronger bond between electroless nickel and the titanium substrate. The suggestion is to add a bake step after the deposition of the electroless nickel. The original question and answer is repeated below with the bake step added.
How can we deposit electroless nickel on titanium parts? F. A.
The key to getting a good adhesive layer of electroless nickel on titanium is proper preparation of the titanium substrate. In the book, Electroless Nickel Plating, Wolfgang Riedel, ASM International, www.asm-intl.org, the following procedure is suggested:
The important thing to remember is that titanium forms a rather tenacious oxide on the surface almost instantaneously when exposed to the atmosphere. Hence, the steps in the above process must be performed rapidly.
