The right procedure to get a perfect electroless (autocatalytic) nickel is to buy a proprietary formula from a reputable vendor of chemicals for plating. Self-made chemistries (home brew) are always short in performance, stability, life and quality of plate they produce. They also lack adequate technical advise. Another wise step is to get a technical book on the subject to be able to better understand what's going on in your baths.

Thomas,

What an obsure and abstract question!

We have no idea what you are trying to plate, what finish you are looking for, what properties you are looking for or if you are working from self-formulated or proprietary chemistry.

To be quite honest, with so little information I would be surprised if anyone could do a good job. Is this supposed to be to a specification (e.g. AMS, MIL spec, ISO, BS etc)?

Give us an idea of what you really want and someone can probably give you a reasonable answer.

Guillermo's advise is the best answer going. The rest of that story is to follow the instructions and the tech service help that they give you. You have no need to reinvent the wheel or electroless plating. If it is a major or a reputable vendor.

Hi, Thomas. Yes, Mallory & Hajdu's "Electroless Plating" [link is to book review on finishing.com] is a very well received book, and there is an excellent chance you will have a high opinion of it as well. We have linked to a few places where you can find it. Plating books are usually quite expensive because they require a lot of work and few copies are printed. So it would be best take a look at it in a library first if you can. Good luck.
