Have any of you good people done any plating with Nickel or Chrome?
The background is that we are making some prototypes for a consumer product. As part of this we are making magnetic flux guides as part of a magnetic latch for an indoors consumer product. Basically the flux guides need to survive fingerprints without rusting.
Any advice would be welcome.

Zinc plating is cheaper and easier. But not as shiny looking. Plenty of kits available. I've a mate who does it on old motorbike parts with great success. He has done nickel at home too, but not chrome. All seems to go well with no great problems.

the home kits for nickel work very well if the instructions are followed exactly. i found it very time consuming as the parts to be plated have to be highly polished and free of any scratches, you can also control the thickness of the nickel by the time it is left in the tank.

Did quite a few motorcycle parts , kits from Gateros. Extremely pleased with the results.

A few years ago but I replated a 1930's motorcycle at home using a Dynic kit that was available in the 70's and 80's, agree with Gary that it is very time consuming. The kit I had only did the old fashioned dull nickel which had to be polished after plating, The results were very good and although I sold it a long time ago I know it still looks good today, There is a copy of " the vintage motorcyclists workshop " by Radco available free somewhere on the internet which has full practical instructions, I followed these to the letter. Only problem I had is that sometimes it is very difficult to get the plating to get into internal corners. I imagine that the Gateros kit is much the same as my old Dynic, I used their Zinc plating kit with very good results, if that is suitable it seemed slightly easier to use than the nickel. I enjoyed the whole thing found it a very satisfying process, almost magical!

I've done bright nickel and zinc plating using home kits successfully. Chrome plating is a no no for home use because of the cyanide content. However, there are substitutes called "Copy Chrome" and "Replica Chrome" if you Google them, though I haven't tried them myself.
Just to repeat what has already been said, the metal prep. can be time consuming if a high polished finish is needed. Even without a polished finish the metal must be absolutely clean before plating.

A good few of my motorcycling friends use the DIY kits and have plated things for my bikes.
I believe they are now finding it harder to obtain the battery acid that is used in the process.

All plating needs super clean surfaces. Nickel plating (and nicasil dipping) is straightforward. Chrome plating isn't and requires toxic chemicals. I did a little, 40 years ago when the toxic items were to be had Would not recommend it now, even if you could get the chemicals. Horrendous problems in disposing of the solutions afterwards, as well. Leave it to the professionals!

As this is a prototype I guess that extreme hard wearing and longevity aren't so important. Many years ago we used "Niculoy" to electroless plate on aluminium, actually to make it solderable but the finish was very bright and corrosion resistant. It is still available, I think we got it from RS but they don't stock it now. Google is your friend.
As the name implies the plating is nickel.

I've used this nickel acetate method with success. I do however use a laboratory type variable DC power supply (only because I've got one)

Years ago I did the nickel plating on the 1929 Morris Cowley shown in my album. I used a recipe that I found in a book from the University chemistry department. Unfortunately I no longer have the recipe. It used some nasty chemicals which were easy to obtain from an industrial supplier at the time. All was done on brass items. For it to adhere properly and last on steel you must copper plate first and you need a cyanide bath to do that well.
If I was doing it now I think I would go to a commercial plating firm.

I have had a handfull of parts bright nickel plated by a local plater for "tea money", just go and ask them if there is one nearby.

I agree with KWIL. Try a local plater. I have sent small batches of items to be bright nickel plated to a company near me and the cost was relatively low.

Austenitic stainless steel is non magnetic and is what most people recognise as rust proof Stainless Steel ( althouigh some grades can rust stain). Martensitic Stainless Steel does have magnetic properties, how ever it is at best a corrosion resisting steel and will rust in the correct conditions.

If you are anywhere near Arlsey in Bedfordshire I have used these people before.
Very happy with the results on all my motorcycle chrome.
PS they really really will not do exhausts!!!!!!!!

The stainless you want is that used for cutlery - go check your spoons with a magnet, It uses chromium up to a certain hardness. Then you have to add Nickel to balance the atomic level stucture. Non magnetic austenitic Stainless "18-8" is so common now it is hard to find other versions (it used to be extra expensive so only used where strength was needed as in nuts and bolts).
