This may be a bit premature but.... I have a heat treat supplier that performs a process known as "atmospheric nitro-carburizing" on ferrous metals. The process is followed by a molten "salt" quench which oxidizes the surface of the material. The atmospheric portion hardens the surface and the temperatures used are non-critical. What this means is that the substrate material is not annealed. There are several benifits to this process over plating processes. First, the surface is hardened to a shallow case of Rockwell 52-55 on the C scale. Second, the salt quench yields a salt spray corrosion resistance in excess of 200 hours (Zinc is 70-75 hours, if I recall correctly. If I don't I'm sure someone will correct me  ) Thirdly, the surface is very abrasion ressistant. By very what I mean is the rotors *don't* wear. I can have this process performed for a similar cost to "freezing" the rotors. The parts must be clean of rust and plating for the process to work.
If anyone is interested in this process let me know and we can do some experimenting.

If I were to buy a set of stock rotors, how much would it cost to have this done?
