Corrosion is a major danger to any metal (including ships) that comes into contact with the soil, whether by air, water, or land. In this post, we will look at the three-step procedure for stopping marine corrosion on a ship: identifying marine corrosion, understanding the source, and eliminating the cause. The technique is the same for all metals in all settings.
Step 1: Determine Marine Corrosion
Marine corrosion can manifest itself in a variety of ways.
Step 2: Recognize the Cause The Science of Marine Corrosion
Metal corrosion is caused by the following factors:
Rust
When compared to electrolytic corrosion, rust has a very low aggressiveness. It is only present when there is moisture in the air (10% humidity or above). Rust can be easily avoided by painting or plating after all electrolytic causes have been eradicated.
Galvanic
Galvanic corrosion is likewise relatively low in aggressiveness when compared to electrolysis corrosion. Anodes can reduce galvanic corrosion, but only after electrolysis has been abolished. Sacrificial anodes can then function as intended.
Step 3: Remove the Source of Corrosion
An electrochemical reaction causes metal corrosion. Electrolysis is eliminated when the electric current is removed. This is accomplished by connecting every metal to the ground via an electrically open circuit (disconnected). Then no current can go in or out, and there will be no electrolysis for the rest of the time. It just takes ten days of stray current over the course of a year to create visible electrolytic deterioration.
Cortec Middle East provides high-quality rust primers, rust preventative lubricants, marine corrosion protection, and metal rust removers. Steel tools, metal parts, cast iron, offshore, long-term indoor and outdoor protection, and marine and tropical climates all benefit from it.
