Rhodium - Is it Really Necessary? - My View

In a word NO!

Expand?

As a lot of you may know a number of Gillette Aristocrat Models were Rhodium plated. What you may not know is that (at least on the ones I've come across) it's only the handle and not the head that is Rhodium plated. The head is just plain old Nickel.

Steve (WPD111) sent me an English Aristocrat model and asked if I could replate it in Nickel. The razor had flaking on the Turning Knob and the Silo Doors and a bit of wear to the head. Now the turning knob is Rhodium plated (over nickel) so you would think that being harder (more wear resistant) that it shouldn't have worn and flaked.

The other big problem with Rhodium is that it is an absolute nightmare to remove. The only way I could remove it without damage to the razor was to steep it in a chemical solution that quickly removes nickel - the Rhodium required around 2 days and regular wire brushing with a brass brush (steel would have scored the finish on the razor) to lift the underlying nickel and the rhodium with it. The razor could then be polished and finally plated in nickel.

Here are the results of my labour and hopefully you will see that the shine and finish of the razor replated in bright nickel is every bit as bright as the Rhodium. In the future (after another 50 years) if it does need replating, it will be a damned sight easier to remove the nickel for replating.

Some will say that the razor isn't original any longer, OK, it isn't, but it looks identical to the original plating and a lot more pleasing to the eye than the flaked and worn 'original'

So, yes, Rhodium is harder and in theory more wear resitant than nickel, but in my humble opinion, it's not at all necessary for a razor - OK for a wedding ring that is constantly worn, but as many will know it does wear and correcting the problem is a lot more difficult due to the removal.

Gillette probably needed a marketing 'edge' for their upmarket model, so specifying 'Rhodium' plating probably provided that edge.

Gillette will take this under advisement. Who knows, they might listen and stop using rhodium plating.

Nice work on the replating.

Thanks Mark,

I suppose Gillette don't have that problem any more - Rhodium on top of plastic or cheap pot metal (as used in their latest offerings) just won't have the same ring to it. They could specify 'Latest 6 blade Rhodium Platinum coated blades with triple lubricating strip and built-in LED' to illuminate the job :)

Would you happen to know what Gillette used for the gold plating? Was it gold plating over nickel?

Don't give them any ideas. :biggrin:

When the plating material is much harder than the metal underneath it cannot deform enough when the basic material gets a dent or is bended too much. So when the turning knob drops or gets a hit and deforms a bit the rhodium cannot 'follow' and will flake off. This is why nickel plating gives less problems than rhodium or chrome. On the other hand can nickel cause allergy problems so every kind of plating has its drawbacks.
 
I know razors such as the Aristocrat were gold, over nickel, over brass. Are you sure about older razors like the New and Old types? If you polish the gold off their caps, you reveal brass or copper, not nickel. Or, are you polishing the nickel off too?

I think that why the gold comes off so easily, if they'd nickel plated the brass or copper 1st they'd have a much stronger bound.

+1 if you want a good gold plating on copper or a copper alloy start with nickel. Gold plating directly works ok on gold and silver as base material (and probably on platinum too; never seen it though). For most platings starting with nickel lifts the quality of the end product dramatically.
 
Indeed as Bob indicates, the 'New's etc were gold plated directly onto the copper or brass, which doesn't bond as strongly as onto Nickel, so these are often found to be worn through to the brass/copper which oxidises and further lifts the gold until you are left with a green mess that you wouldn't want to put anywhere near your face.

It's a straightforward job to clean, polish and then nickel plate to give a shiny 'new' razor though - or even gold plate over the nickel to provide what should have been done in the 1st place.

While it is true that as brilliant a shine can be presented on a nickel razor as with a rhodium razor, the true difference is in the tint. There is something about the tint of rhodium that is more pure than the yellowish tint of nickel. Even the whiter tint of silver doesn't quite match up to rhodium. Chromium probably comes closest as far as a semi-standard razor plate.
