Minimum service temperature for electroless nickel plating

A. Hi James. I see no warnings against low temperatures for electroless nickel in such references as "Electroless Plating" [on eBay , Amazon, or AbeBooks affil links] , Dini's "Electrodeposition" [on AbeBooks, eBay, or Amazon affil links] , or Gawrilov's Chemical (Electroless) Nickel Plating ⇦[this on on Amazon, ... on AbeBooks affil links]. And -79 °C isn't much colder than dry ice, whereas electroless nickel has been used at -183 °C to protect titanium from liquid oxygen.

So the question will probably not be whether electroless nickel can reliably endure -80 °C, but whether you can get sufficient adhesion to aluminum to withstand the high coefficient of expansion of aluminum vs. the low coefficient of expansion of electroless nickel. Hopefully some reader will volunteer some practical experience but, pending that, it would seem to me that if the temperature difference from -80 °C to room temperature is 100 °C, and if you can use electroless nickel plated aluminum at 100 °C higher than room temperature, then you should be able to use electroless nickel in this application.

Luck & Regards,

Make sense Ted. Thank you very much for your valuable input!
