Translation in Greek

Electrolysis is the phenomenon by which metals are exchanging ions among them when immersed into the sea water or other liquids. All metals are loaded either negative or positive (static electricity) according to the amount of positive or negative ions they have (over and free) at their atoms.

When two or more dissimilar metals are immersed and in permanent contact with sea water or other liquids they exchange their ions trying to create a balance electrical field. The negative ions (cathode) are pulled by the positive (anode) and this movement of the ions goes with the lights speed (300.000 Km/sec). This is to say the negative ions are bombing the metals whose atoms have more positive ions with the result that these metals deteriorate.

When a 'zinc/aluminium/magnesium or other metal alloy' (called as well 'anode') are placed close by, these positive loaded metals (anodes) pull towards themselves the free moving negative ions and thereby protect other metals from being deteriorated.

Cathodic protection is one of the most effective ways of reducing or eliminating the corrosion damage that inevitably affects metals (iron in particular) that are in permanent contact with sea water or other liquids.
It also provides effective protection for buried metal structures, which are equally affected by corrosion in situations that are often worsened by stray currents from fixed dc systems (railway lines, power transmission lines, etc.).
Paint provides only limited protection over time for ship’s hulls, port structures, sea lines, platforms, etc. This means effective cathodic protection system must be implemented using sacrificial anodes, impressed currents, or systems combining both.
The fundamental parameters in sizing sacrificial anode or impressed current cathodic protection system are:
• calculation of the surface to protect
• surface geometry
• expected life-cycle of the structure
• environmental conditions
• structure operating conditions
