Does anyone know much about this technique? 30 years ago, the company I worked for used to use ENP as part of an in-house test procedure. We just needed small bits of all kinds of metal plated very quickly, so we did it in-house using a solution made by the Cannings company (Birmingham) and called Niffoss (bought in 25 litre tubs). It was amazing stuff; most of the time you just heated it to 60'C and threw your item in. I once saw a pair of leather shoes, belonging to someone's baby, very nicely plated as keepsakes! Most of the real work were samples which were heavily oxidised, but that did not seem to matter. Very rarely, a sample seem slow to respond, but we had some tricks and it very rarely (if ever) failed. The plating that formed was quite hard and quite corrosion-resistant.
Some time later, and at another employer, I tried to buy Niffoss, only to find that Cannings were no longer in business. I think they had been taken over by an American company and they offered their own plating solutions, and when I said I only needed "small" quantities, they "hung up".
Anyone doing ENP? Seeing some of the problems being described with galvanizers, this process might be an interesting alternative.
