I understand mild steel is very bad at out gassing so is never usually considered for hard vacuum applications. But if the decision was constrained by other factors would it be possible to apply a surface treatment or coating to the internal walls of the vessel - am I correct in assuming that as long as the chambers structure is up to the task of withstanding the external pressure any internal surface skin only needs to withstand the small non-accumulative forces of individual atoms 'attempting' to out gas from the inner thickness of the walls?
The 'other factors' constraining my decision to use mild steel is I have an old fire safe with 0.23 m3 internal space that I would like to turn into some sort of vacuum deposition chamber Oh and this thing is located on the second floor of my building and probably weighs in at a tonne so it's not like I can send it to get plated ;).
