Conductive paste used in very low pressure situation

[Semimaker]

This might seem off the wall but does any one have experience with using a metal paste (e.g. Arctic Silver?) in low pressure and dynamic conditions.

I have slightly worn metal plate which metal chucks revolve around the perimeter. The plate is internally cooled by water and the chuck need to be also cool. This is where the thinking for AS comes in, I know it's good in a static situation at normal pressure but what about down to approx 1e10-4 torr? Would it just degas? or would the movement gunge up the chucks and the plate?

Thanks for any feed back, I may have to resort to just trying this anyway!!!

Cheers,

is this chuck gonna be lubricated by the AS??(like, since this chuch moves, are you gonna be putting the AS b/t the chuch and whatever it is moving around) If it is... I wouldn't try it.... AS is made to be a thermal conductor not a thermal conductor/lubricator. The pressure SHOULD have no effect on it... that is SHOULD.....

I agree with buzzman, it sounds like even if U dont want it to, the AS needs to act as a lubricant. I dont think it would work for extended periods of time either

Do you need a conducting paste? Or a lubricant???

For a vacuum lubricant, go here.
I have ordered vacuum stuff from them before, and I like them. Prices are not too bad.

For conducting pastes, I don't know.

AS is formulated to thicken when it heats/cools several times...it would realy gum up your works...

But if you are not realy concerned with that (friction is of little concern except for the heat angle), then i doubt low pressures will have much of an effect...
