Seeking knowledge of Nickel strike



(-----) 2004

Dear Sir/Ms.

I would like to get your advices about how to do " Nickel strike " on top of a nickel coated metal plate.

The purpose of the additional nickel layer ( nickel strike) is just to achieve better adhesiveness when the nickel striked metal is glued with another metal plate ( Zn coated)

Many thanks.

Doing a nickel strike on top of old nickel plating is a workable process sometimes used on items like truck bumpers. In today's environmentally attuned times, it is sometimes deemed better to rectify some plating defects by adding a second layer than by stripping the original layer and having to deal with the waste from the stripping solution.

Personally, I've only heard of this being used as a workaround for defective parts in that way, not as a design strategy for new parts. For new parts, it's perhaps better to try to keep the nickel plating active rather than trying to re-activate it with a nickel strike.

A conventional Wood's Nickel Strike is suitable for the purpose of reactivating nickel plating.

I would try using some time of acid salt with current to reactivate the nickel.

If glue is the next step on top of the original nickel, probably no chemicals are needed. A thorough dry or wet/dry scrubbing with Pumice [affil. link to info/product on Amazon] or Scotch-brite might be all you need.
