Electronic Vechicle Corrosion Control, Are You For Real?

[Kinks]

I did my apprenticeship on shipping, There are guys who specialise in this area (those blocks are Zinc) and get an iron block with sea cooling to have zero corrosion, They use small zinc anodes inserted into the motor cooling passages and an electrical current to protect the inner sufaces. Of course the annodes wear away reguarly and require yearly checks.

In that case you have an easy complete circuit though.. The zinc and iron block are your two electrodes and the coolant is the electrolyte.

The only electrolyte I can see with this "rust stop" thing is rainwater.. which would do a marginal job at best even if the car (and zinc rust stop device) was covered in a film of water (which it wouldn't be).

You'll find alot of 4wd uses those device, been a 4wd owner who frequent fraser Is. alot, for it to works properly the protected item has to get wet from time to time, otherwise, it's as useful as tits on a bull. It uses the same voltage correction technology as steel ship. The navy runs steel vessel and has a much more complex abeilt same theory set up.

if it's an M3, would washing the car, say once a week, be a regular enough dosing of "electrolyte" ie water?

saw one in a brand new pajero i did a service on..

heh anodes will crode before any other solid material under salt water. Considering you run salt water throught your engines on boats.

I think rust or corosion is caused by ferons (excuse spelling) leaving the metal.

I think the electric current can restore the ferons in the metal salt water takes out.
