#28410, "RE: zinc vs. cadmium coated rotors??" In response to Reply # 0
Hmm. Correct me if I'm wrong, but don't you think the coating would wear off quickly on a part that sees so much friction? Now, if the rotor were MADE of different metals, I would think that it might make a difference, but just a coating? I know that my rotors get corroded on the face after a rain storm, but a minute or two of driving takes care of it.

PS. I've heard that cryogenically (sp?) treating them affects rotors. I'd be interested if someone has some insight on coatings like zinc or cadmium.

yea but what i mean is not the surface of the rotor that touches the pad, but the rest of the rotor like the edges and the such....

typically cadmium is better than zinc as far as corrosion properties. But of course that always depends on more specifics of the actually plating/process/thickness used to plate.
It could be .001 thick cadmium vs .004 thick zinc,etc...
