Black oxide classification
I'm master of science student and I'm currently working with a project about black oxide. Are there any quantitative (or qualitative) methods to classify properties of the oxide layer like the ability to attach to the steel or the ability to crack?
Grateful for any help!

Hi, Maria. We have an FAQ on line here comparing
Hot Black Oxide vs. Cold Blackening. The cold blackening is proprietary selenium compounds which you could investigate with the vendors, but true black oxide is a special kind of "rust" and is only millionths of an inch thick, so I don't think adhesion and cracking are ever issues with it. Good luck.
Regards,
