I am looking for some pointers to information on the subject of
anodic/cathodic(terminology please) system of rust prevention/inhibition.
Preferably, I need technical information on the chemistry involved in
both the sacrificial and non-sacrificial systems. Also on the difference
between gel-cel and solid(metallic ?) systems.
Any opinions on the workability,reliability and general perform-
ance of these systems would be appreciated.
All of the above should reference the automotive industry, although
general information on marine systems would be helpful, also
EMAIL if at all possible.
Thank you in advance.

I do not see how electrolytic protection (cathodic protection) is applicable to automobiles as they are not generally in a conductive or electrolytic environment. The common use for cathodic protection is in ships or underground piping where the material to be protected is surrounded by water or moist soil which is electrically conductive. In any event, the following references should help George any anyone else interested in this form of corrosion protection. "Fundamentals of Cathodic Protection", "Corrosion Cathodic Protection and Common Sense", and "Cathodic Protection - One Way to Prevent Underground Corrosion". These three papers were written by B. Husock of Harco Corporation, Cathodic Protection Division, 1055 West Smith Road, Medina, Ohio 44256. Harco can provide copies of these papers for a small fee. These references are somewhat dated and I do not know if Harco is still in business. If you cannot locate them any other way, I can provide a copy.
