Anti-seize goop works on the principle of sacrificial anodes, but the
anode is powdered. ok.

So does that imply that, just like the zinc on a boat, the goop
eventually is no longer electrochemically protecting the joint?

If yes, should the protection be TESTED on some periodicity?
If yes to that.... how?

Can't speak for what your using, but we used a anit sieze compound
called Silver Goop, while I was in the USAF. It had a shelf life on
it, and we bought and threw lots of that stuff away over the years. I
drug some home and it appears to work fine, but you know how aerospace
vehicles and uncle sam is with policies and tech orders. It was pretty
darn pricey stuff IIRC.

Jo Ann asked Dr. Sooooooooooooooooolow to remind people that while she has retired from selling GF (and sold
the business to Ken Fischer http://dandyorandas.com/) she has NOT retired from
helping people with sick GF and koi FOR FREE. 251-649-4790 phoning is best for
diagnosis. but, can try email put "help sick fish" in subject. Get your fish at Dandy Orandas

I've got a can of "990" high-temp anti-sieze that I got 30 yrs. ago that was
used on P&W 2800 engines on DC-6's. Still good as I broke something loose
from a very high temp. location the other day. It had been on the bolt for
a couple years. I wouldn't worry about shelf life.

Well, the anti-seize compounds I like contain either nickel or stainless
steel. Both, as well as copper, are too close to iron in the
electro-chemical series to be effective anodes, don't you think? So, I
doubt the sacrificial anode theory. Besides the vehicle is oil which is
hardly an electrolyte. I don't think you have to worry about shelf life in
the ordinary commercial anti-seize compounds. I have never seen an
expiration date
on one.

?? Cites, please. Some I've used has had graphite in it, no way that's
going to be an active anode with steel, aluminum or copper.

I assume you're talking about testing the stuff on the bolt or
fastener, not shelf life in the can, and I have no way of knowing how
you'd do that short of loosening every fastener up to see if it would
turn.

I always figured the stuff worked as "insulator", it kept like metals
from welding together under pressure by filling in the microscopic pits
and grooves and the oily carrier kept rust from developing. By keeping
air out of the joint, I think it keeps rust from forming. I don't
think it's an electrochemical thing at all.

In plugs and sockets, they speak of a "Gas Fit" or not. A gas fit
means once mated, gas cannot enter between the two metal contacts. This
increases the lifetime and quality of signal like all out doors.

Gas is simply what is floating around - lots of odd stuff other than Oxygen.
Chlorine gas for example. Gas can aid in the joining of metal by corrosion or
aid in the voltaic nature.

This was an eye-opener for me too. ( I added rec.boats.building to the
list for reference and removed a hobby group. )
