Graphite Used As A Corrosion Inhibitor
Graphite Used As A Corrosion Inhibitor
(OP)
Has anyone ever heard of adding a small quantity of graphite to an automotive cooling system to inhibit corrosion?
I discovered the attached link, which describes it, but can find no other references to the practice anywhere.
I wouldn't expect the idea to be much of a money maker for any company, considering the price of graphite and the quantities involved, so that's not much of a motivation.
It does seem that their 'research' is purely anecdotal, does anyone think it makes any scientific sense?

RE: Graphite Used As A Corrosion Inhibitor
it seems that the mechanisms of corrosion prevention is that the graphite will coat the entire internal surface preventing oxygen to reach the surface.
I don't understand how graphite added to the fluid will reach and coat the entire surface...

Also, anitfreeze already contain corrosion inhibitors which coat the surface of the metal...

I love materials science!

There were claims that these products also help prevent corrosion to the cooling system, also lubricated the water pump.
I have two of these cubes in a box in my shop desk.
