Rust is a naturally occurring electro-chemical reaction.

The iron, steel, etc. is trying to revert to its natural state, i.e. iron ore. A good example: A hunk of iron ore, freshly mined, and an old engine block left out in a paddock for about thirty years – look similar.

In an electrochemical reaction (rusting for example), a substance is said to be oxidized if it gives up one or more electrons when combining with another element. Conversely, a substance is said to be reduced if it takes one or more electrons when combining with another element.

Rust occurs in two forms:

  • Surface rust occurs when bare metal is left in moist air. This type of rust is a direct reaction between the oxygen and water in the air and the bare steel and in most cases will be nothing more than a harmless surface coating.
  • The second form of rust that occurs involves an electrochemical process much like a battery. Ferric ions are formed at some weak point in the metal a crevice, dint or heat stressed area, etc.

Fe (solid) => Fe2+ + 2e

This becomes the anode or negative terminal of our battery and begins to pump electrons into the car body. At a region remote to this where the water-air surface meets the metal a second reaction occurs. The electrons from the anode are combined with oxygen in the air and the water to produce hydroxide ions.

O2 + 2H2O + 4e ==> 4OH

These Hydroxide ions combine with the ferric ions produced earlier and solidify as rust. Because this form of rust favours removal of metal in pits, it is very destructive. Electrochemical rusting is responsible for eating holes into panels and causes rust to bubble underneath the paint.

Understanding the rust process helps to illustrate just how CAT does work.

If the paint of a motor vehicle is damaged then the metal can become exposed to a number of elements that combine to damage or rust the metal.

The CAT SYSTEM Rust Protection protects your car by an impressed current producing negative electrolysis.

Should the metal of your car become exposed to the elements (paint weakness or scratch.) the “field” provides the electrons sought by the water and salts that are “attacking” your vehicle, thereby leaving your car intact and rust free.
