Hi,

Problem is that irons (and indeed chondrites) actually contain a
[mixture] of metals and there therefore is an electronic potential
between different metals which is aggravated by water. In a vehicle/car
which is nearly all the same type of steel, electronic protection will
probably work ok, since all surfaces are nicely earthed to the auto/car
chassis. But I doubt if it would work on the dissimilar metals such as
those in meteorites because you could never even out all the charges.

Vapor Corrosion inhibitors' or VCI's are chemical emmiters that stop
rust they work in a much different way, they emit a molecular coating
which settles on the meteorite / metal surface just a few atoms thick,
and stop the air/water from reaching the surface thus stopping rust. The
coating is so thin that it is not even noticeable but it really does
work and is used extensively for this purpose.

Here's a bit of info while I was investigating anti-rust..
=20
The vapor emitters are fascinating, but how about for our open-air
specimens on displays?? This may be prohibitively costly...I'll have to
await their reply to my inquiries. =20

This system is for 4WD's, SUV, auto's, but I imagine it might be
adaptable for our larger meteorites. Anyone out there with rusty 300 lb
Campo's??

The CounterAct electronic rust prevention system uses a process called
'capacitive coupling' to apply a measurable current to every metallic
component of a vehicle that's earthed to the battery. A small unit,
usually mounted on the firewall, detects the amount of power required to
create an electrostatic field that will keep the metal structure
electron-rich and then provides that power, reducing the ion mobility
that's the basis of the corrosion process, The unit is fed from the
vehicle's battery, drawing about as much current as an LCD clock.
So the system operates by applying one of the principles of
electrochemistry - that an oxidation reaction can be slowed or retarded
by creating a surplus of electrons to the metal from a supplementary
source.
