Do any of you guys know of someone that re-coats the surface of flywheels?
Thanks,
John

John, the only coating I'm familiar with is the copper plating on a 67S flywheel and clutch,,,,is this what you mean?? but i don't know of any where that does that either.

You might call Bob Barnes at Verne's Chrome Plating, (323) 754-4126. Like any good chrome plater, they start with copper.
Bob may have enough of a metallurgy background to know what you need. He started at TRW.

I don't think it looks like electroplate as the surface condition appears incorrect. I would also worry about hydrogen embrittlement which can even occur during electroless copper plating.
I believe it is more likely to have been flame sprayed which now would tend to be replaced by a Plasma technique or even cold spraying.

The only reason that I can think of for applying this coating is to improve the surface contact between the clutch plate and flywheel as an aid to heat transfer.
I have some flywheels that I got from Dave White some years ago that are aluminum with a plasma spray coating applied. The plasma spray replaces the usual metal insert that is used on aluminum flywheels. I don't have any that will work with the early (pre 1970 engines). Whatever the coating is/was works very well, we have used them on many race engines with no problems.
Wasnt the copper faces a failure and discomtinued fairly soon?
The RSR had a Clutch with an aluminium pressure plate that was flame spayed with Tungsten Carbide and I think KEP make them in this format.
I would tend to agree that the copper plating is not the greatest idea as it isn't something that would make good engineering sense.
If anything a copper coating is likely to reduce friction.
