GGs, I was admiring a nickel plated iron plane on the 'bay the other day. It was in generally nice condition and was advertised as not having been cleaned and showed light rust in some places. My initial thought was the rust would likely clean off pretty easily. Thinking more, or perhaps over thinking, I tried to do some googling for the color of nickel oxidation and couldn't find a satisfactory answer. I think oxidized nickel is simply dull nickel looking. Anyway, I'm thinking the presence of rust on a nickel-ed plane indicates plating loss and rust of the underlying iron. Perhaps there is a metallurgist out there who can confirm my conclusion. Bill W.

I have an older #90 (Stanley small rabbet plane, Jeff) that per B&G is nickel plated, and this one looks like nickel rather than chrome. There are some areas where the nickel is gone, and the surface underneath has a dull reddish-brown color. Rather than rust, this looks more like a plating applied prior to the nickel. The surface is smooth and the color doesn't rub off on my hands. I seem to remember that for some materials, copper is applied prior to the final plate to help the final plate adhere, but I can't point to a reference now. FWIW, Norm - Madison, WI |

FWIW, modern nickel will not stick to steel. Norm is right, there is copper plating underneath. I don't know if the historic nickel alloy will stick directly to steel. Maybe someone like M of A can help us. Gary K Albion NY, USA ---- Norm Wood |

Some (if not all) of the later Millers Falls tools have chrome instead of nickel, and you can pick it out right way on comparison. The chrome has a blue tinge to it. Cars used to have nickle bumpers too. Ed Minch |

The rust can work its way under undamaged nickel and destroy the connection with the substrate, leaving the plating weakly attached to the rust. A surface that looks almost solid plating may have almost none of it adhered properly. I once picked up a plated center punch in the street. It was badly nicked and battered from being run over by cars, but it looked like almost all of the plating was still in place, with just small spots of visible rust. After an our or two in citric acid, most of that plating was at the bottom of the solution, and there was almost none left on the punch. Each pinprick hole in the plating had caused rust under the plating the size of a pin head, and there were so many that they joined up. Not the only case I've encountered, but the most dramatic.

Nickel is always plated over top of copper plating. Nickel itself is not easy to plate and needs a foundation. The old recipe for chrome was copper, nickel, chrome You had to plate 3 times to get chrome, since it practically doesn't stick to anything else but nickel. Of course they are chrome plating pot metal and plastic now, and I have no idea how. just the old stuff maam lol yours Scott -- ******************************* Scott Grandstaff Box 409 Happy Camp, Ca 96039 scottg@s... http://www.snowcrest.net/kitty/sgrandstaff/ http://www.snowcrest.net/kitty/hpages/index.html |

Hi All On the rusty nickel issue I worked for a few months in a plating shop in the 70's during my engineering apprenticeship, there they would degrease the part, copper flash, a few 10ths I think, then nickel plate and finally chrome plate prior to polishing the nickel, the copper is there to aid adhesion of the nickel to certain materials, all a bit vague now though due to the time passed. Hope this helps. Regards Steve, in good ol UK. |
