What the device is for: The "Akor" electrochemical protection device allows you to forget about the expensive anti-corrosion treatment of the body. The installation of the device takes only 30 minutes, so you forget about rust forever. On new cars, the formation of corrosion is prevented, and on used cars, the spread of already formed corrosion is stopped. The effectiveness of the device is confirmed by the results of independent research and many years of operating experience.
Background: Cathodic protection was first described by Sir Humphry Davy in a series of reports presented to the Royal Society for the Development of Knowledge about Nature in London in 1824. After extensive tests, cathodic protection was first applied in 1824 on the ship HMS Samarang. Iron anode protectors were installed on the copper hull of the vessel below the waterline, significantly reducing the rate of corrosion of copper. Copper, corroding, releases copper ions, which have an anti-fouling effect. Due to excessive fouling of the hull and reduced efficiency of the ship, the Royal Navy of Great Britain decided to abandon the sacrificial protection in order to take advantage of the antifouling effect due to the corrosion of copper.
The corrosion process resembles the work of a galvanic cell, since steel is mainly an alloy of iron and carbon, that is, substances with different electrode potentials. When electrolyte gets onto the surface of such an alloy (water, dirt from the road with salt content), an electrochemical reaction starts between the molecules of iron and carbon, accompanied by the dissolution of the anode (iron) and its transition into hydrates, and then to oxides.
The principle of operation of the "Akor" device is based on the creation of a galvanic pair between the car body and additional electrodes.
The potential shift of the protected metal object is carried out using an external stabilized DC source.
There is a method of cathodic protection without an external power source, using a sacrificial anode made of a more electronegative metal, relative to the car body. At the same time, the surface of the body becomes equipotential and in all its parts only the cathodic process proceeds. Corrosive anode process is transferred to auxiliary electrodes. The disadvantage of the cathodic protection method without an external power source is: lower efficiency, smaller radius of action, it is necessary to clean the car body.

ELECTROCHEMICAL CATHODE PROTECTION of metals against corrosion, based on the dependence of the corrosion rate on the electrode potential of the metal. In fact, the electrochemical protection includes cathodic protection, in which the potential of the metal is specifically shifted from the area of active dissolution to a more negative area relative to the potential of corrosion.
The shift of the potential of the metal is carried out using an external DC source (cathodic protection station) or combining with another metal that is more electronegative in its electrode potential (the so-called tread anode). In this case, the surface of the sample to be protected (construction details) becomes equipotential and only cathodic processes take place in all its parts, and anodic processes causing corrosion are transferred to auxiliary electrodes.
Cathodic protection is widely used to protect against marine corrosion. Civilian ships protect with A1-, Mg- or Zn-sacrificial anodes, which are placed along the hull and near the screws and rudders. Stations of cathodic protection are used in cases where the need to disable protection to eliminate the electric. fields of the ship, while the potential is usually controlled by silver chloride electrodes. There are automatic cathodic protection stations located on the vessel or on the shore (when moored or repaired). Anodes are usually made of platinized titanium, linear or round, with near-anode non-conductive screens to improve potential distribution and current density along the hull.
Especially important is the use of cathodic protection for stationary oil and gas facilities, pipelines and storage facilities on the continental shelf. Such structures can not be entered into the dry dock to restore the protective coating, so electrochemical protection is the main method to prevent corrosion. The offshore oilfield rig is usually equipped with tread anodes in its underwater part (there are up to 10 tons or more tread alloys per tower).
Methods for cathodic protection of bodies of transport equipment (automobiles) are being developed.
Protector anodes are used to protect otd. decorative elements of the body, with electronic devices provide a constant or pulsed current. To increase the coverage of the protection is necessary to place the anodes in the naib. corrosive points or use electrically conductive paint. The device generates currents to control the cathode electrodes (supplied).

Electrodes are installed with epoxy glue to the places where corrosion is most likely.
When installing, remember that:
- protective electrodes are installed only on the places protected by a paint and varnish covering. There should be no contact with the mass.
- for bonding electrodes, you can only use epoxy glue or putty based on it
- the outer side of the protective electrodes must not be coated with mastic, paint, glue or other electrically insulating coating
- 1 - front lower part of the rear wing and wheel arch at the junction with the wing;
- 2 - places of fastening of headlights and sidelights;
- 3 - cavities behind the front fenders;
- 4 - internal surfaces of doors and thresholds;
- 5 - bottom.
The electronic unit is installed near the battery, the red wire is connected to the battery terminal "+". That is, the electronic unit remains on even if the general electrical equipment of the car is turned off. The blue wire connects to one or two electrodes.
In general, the device consumes no more than a car clock and ensures long-term efficient operation even with a highly discharged battery.
We recommend installing electrodes in the following places:
