I'd give way too much for a NOS rear brake disk for my 1985 1300. Unfortunately, "Way too much..." doesn't seem to be important, they're aren't any.

Years ago I interviewed for a couple of jobs that involved using some sort of plasma system to spray metal onto worn aircraft parts to allow them to be remachined and reused.

Foward thirty years: Why can't I just weld em up?

Probably because they'd warp unpredictabally.

The real question is hasn't any one figured out a way to resurface brake disks?

Been awhile since I've done any real technical reading on the process you're referring to - metallizing.

Used to be done to high-buck value industrial machinery - shafts, trunions, high-wear pieces that would be extraordinarily expensive to replace - and as an anti corrosion treatment to items like jet engine compressor stages.

Still can be done, but I think the process has been bypassed technologically by solid-state lubricant bonding with teflon and ceramics.

Mostly done for corrosion control now, it seems...

Anyways, my guess is that between the deposition alloy, the area involved and the machine processes necessary to spec out a disc, it just ain't cost effective - easier and cheaper to get a 12" steel rod blank and machine a new disc.
