Hello,
I found a sealable aluminum vessel that seems perfect for a vacuum chamber.
However, the aluminum on the inside is anodized and coated with BR127.
This coating is supposed to be corrosion and heat resistant, but I wonder if the BR127 can handle Deuterium plasma without dirtying it up.
Has anyone ever worked with this coating in a chamber?
Thanks,
Jonathan

For low vacuum you will probably be ok, if you were going to high vacuum I would say no, the anodizing is porous and will outgas for a long time. I have no idea what the primer will do, I would try to remove it somehow.

Thanks.
I will clearly be in the high vacuum range before I add the Deuterium.
I might try to sand-blast it down then if I don't find another chamber.

Re: Working with a coated chamber
You can send back to an anodizer to have it etched again which will completely remove the anodize (and it's generally not expensive either), but I think the damage is already done and will only get worse upon removal. Again, the process is called "etching". As Jerry already said, anodizing (first etching step) creates a porous surface, removes corrosion, etc in preparation for anodize. Not an ideal surface for vacuum.
