Has anyone ever done or seen this?

I have a permitted hard chrome plating shop and would like to learn more about how this is done.

I recall reading somewhere that this is done by vaporizing a thin chrome wire that is suspended down the center of the bore.



A quick Google search only gives a parkerizing like home chrome plating setup: Yahoo Link

That's decorative chrome, a common misconception.
Decorative chrome is a multistep process.
Usually nickle plate over a flash of copper, and finally a trivalent (soft) chrome finish, buffed in between.

Hard chrome is a different animal entirely.

For the first post;
There is mostly misinformation and in correct assumptions here.
Vapor deposition is not the method used.

For the second;
The government has been trying without success to find replacements for hard chrome for some years now.
Mostly because of pollution issues, however modern plants like ours emit little to no pollutants.
