Hardcoating for deep vacuum application


I'm looking for a process where hardcoating can withstand deep vacuum (10Ø5) without "outgasing".

Any help appreciated !

It would seem logical to use vapor deposited coatings, since they are deposited in hard vacuums. There are many commercial companies offering physical vapor deposition or chemical vapor deposition of TiN, ZrN, et al. None of these should outgas at your pressure level.
