As in will not fall off?


As in will not stop working?

The former makes a lot of sense, and is quite obvious. The latter is an interesting claim. Is it really difficult to damage the etching's properties? Can I take a sharp knife to the finish over and over again without damaging the finish?

Also, is it oil proof? Most of what I cook has some of that too. IF its impervious to water souluble messes and sucks at oil, well thats better than nothing, but not worth much.

It won't fall off: it is the metal material itself, and it won't stop working until there has been enough abrasion to the outer structure and that would normally take a long time. Vigorous knifing probably would damage it but not all that much, it might not even be noticeable, metal files, sandblasting, acids (if they manage to touch it), and severe oxidation (same disclaimer) would wipe it out completely and the only question is how fast.

I hope they make a few small RC boathulls of this material to test that. If that works it should reduce drag a lot and save a lot of energy/money. Next up would be submarines lol :D If it works it's like supercavitation without the supercavitating, without any gas/air.

I wonder if barnacles are able to stick to this? Unpainted of course, painting this stuff is out of the question and it might be tricky to get it in any color but black (the color it already has) using nanopattering since that would impact the nanopattering they're already doing for hydrophobicity.
