Why the device is needed: The Acor electrochemical protection device allows you to forget about the expensive anti-corrosion treatment of the body. The installation operation of the device will take only 30 minutes, so you will forget about rust forever. The formation of corrosion is prevented on new cars, and the spread of already formed corrosion is stopped on used cars. 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 Humphrey Davy in a series of reports submitted to the Royal Society of London for the Advancement of Nature Knowledge in 1824. After lengthy tests, cathodic protection was first applied in 1824 on the HMS Samarang. Iron anode protectors were installed on the copper hull of the ship's hull below the waterline, significantly reducing the rate of copper corrosion. Copper, corroding, releases copper ions, which have an anti-fouling effect. Due to the excessive fouling of the hull and a decrease in the efficiency of the ship, the Royal Navy of Great Britain decided to abandon the tread protection in order to benefit from 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 an electrolyte (water, dirt from a road containing salts) gets onto the surface of an alloy, an electrochemical reaction begins between the molecules of iron and carbon, accompanied by dissolution of the anode (iron) and its transition into hydrates and then to oxides.
The principle of operation of the Acor 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 current source, using a tread anode made of metal more electronegative relative to the car body. At the same time, the body surface becomes equipotential and only the cathodic process proceeds in all its parts. The anode process causing the corrosion has been transferred to auxiliary electrodes. The disadvantage of the method of cathodic protection without an external current source is: less efficiency, shorter range, it is necessary to clean the car body.

ELECTROCHEMICAL CATHODIC PROTECTION of metals from corrosion, based on the dependence of the corrosion rate on the electrode potential of the metal. Actually, electrochemical protection includes cathodic protection, in which the metal potential is specially shifted from the region of active dissolution to a more negative region relative to the corrosion potential.
The potential shift of the metal is carried out using an external DC source (cathodic protection station) or by connecting to another metal that is more electronegative in its electrode potential (the so-called tread anode). In this case, the surface of the protected sample (structural details) becomes equipotential and only cathodic processes occur in all its areas, and the anodic ones that cause corrosion are transferred to auxiliary electrodes.
Cathodic protection is widely used to protect against marine corrosion. Civilian vessels are protected by A1-, Mg- or Zn-tread anodes, which are placed along the hull and near the propellers and rudders. Cathodic protection stations are used in cases where protection is required to be turned off to eliminate electrical problems. field of the ship, while the potential is usually controlled by silver chloride electrodes. There are automatic cathodic protection stations located on the ship or on the shore (during parking or repair). Anodes are usually made of platinum-plated titanium, linear or round, with near-anode non-conductive screens to improve the distribution of potential and current density along the hull.
Especially important is the use of cathodic protection for stationary oil and gas facilities, pipelines and storage facilities for them on the continental shelf. Such structures cannot be inserted into the dry dock to restore the protective coating; therefore, electrochemical protection is the main method of preventing corrosion. An offshore oil derrick is usually equipped with tread anodes in its underwater part (up to 10 tons and more tread alloys per one derrick).
Methods of cathodic protection of the bodies of transport equipment (cars) are being developed.
Protective anodes are used to protect det. decorative elements of the body, while electronic devices provide direct or pulsed current. To increase the protection coverage, it is necessary to place the anodes in the naib. corrosive spots or use conductive paint. The device generates currents to control the cathode electrodes (included).

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 when the vehicle’s general electrical equipment is turned off. The blue wire connects to one or two electrodes.
In general, the device consumes no more than a car’s watch and guarantees long-term effective operation even with a very low battery.
We recommend installing the electrodes in the following places:
