Black Chrome ZR1's
On ebay, at the AFS store, I saw some ZR1's that were called 'Black Chrome'. What exactly is black chrome? And why the heck is it way more expensive than regular chrome? Also, does anyone else sell black chrome ZR1's? I really liked the way the looked but they seem real expensive to me. Thanks for any help!

Re: Black Chrome ZR1's
At the Indy dealer expo for powersports there was a quad set up with what I called "black chrome".The owner explained that it is a black nickel finish.The chroming process is actually a few different steps before any chrome is adheared to to the surface,and 1 of those steps is the nickel coating.I don't know if this helped or not.

Re: Black Chrome ZR1's
Found this..
Black Chrome is a semi hard, non-reflective, abrasion-resistant, heat and corrosion resistant coating (approximately .0002” thick). The Black Chrome finish can be rendered very lustruous for consumer decoarative applications; and clear coated for a functional use. The Black Chrome process has poor throwing power; and conforming anodes are necessary for coverage on intricate shapes. This coating is applied after heat treating and all mechanical operations are performed.
The Black Chrome surface may be waxed or oiled to darken the surface. Coating provides limited corrosion protection, but added protection can be obtained by specifying underplate such as nickel or copper.
The coating color is a dull dark gray, approaching black; and becomes (black) pearl-like when polished. It shall approximate color plate 37038 of Fed. Std. No. 595. Steel parts with Rockwell hardness in excess of Rc 40 shall be stress relieved prior to plating by baking one hour or more at 300° F to 500° F and baked after plating 375 F° ± 25 F° for 3 hours minimum for induced hydrogen embrittlement relief.
