Baking needed after nickel plating of neodymium?

2004

I'm looking for an opinion on whether nickel electroplated neodymium magnets need to be baked for relief of hydrogen embrittlement. The material is already brittle, so does it need it. Also, I don't think SAE spec AMSQQN290 would apply because the base material is not steel, copper, or zinc.

Thanks in adavance for any help.

Your customer is the only one that can answer that question. A small part would possibly depend on the exact plating cycle needed. Is there any reason to not bake?

As a customer, I would like to see some results of notch bar testing with the bars made out of the identical material with a base line from unplated bars.
