QPQ vs. Black Zinc

[joelande]

I am looking for a direct comparison between the corrosion resistance of black zinc vs. ferritic nitrocarburizing. I can't find anything relating to QPQ that will give hours to white or red rust. I have some info that shows black zinc without a sealer at 72 hours to white rust.

I would suggest you contact Kolene for that information.
