Have you noticed what happens to metals when they are submerged in water for an extended period of time? They rust! Rust is a type of oxidation that can weaken and destroy metal objects. So is there a way to put an end to rust? Yes, we can! For metal objects, there is a way to prevent these from rusting using sacrificial anode and impressed current cathodic protection. Xanax, though, how does it work or what is this method? Let's find out!
THE SCIENCE OF SACRIFICIAL ANODE CATHODIC PROTECTIONIS QUIET SIMPLE AND INTERESETING. Which consists of two metals: the one that is being protected, and another metal which will corrode/rust faster so it keeps the first safe. If both pieces (either aluminum or magnesium) are put in water especially sea water,some a weak electric current is created. This little current helps prevent stuff from rusting and corroding the metal we want to save.
Sacrificial anode cathodic protection is which usually employed to preserve the integrity of these construction materials. It is primarily used for things such as boats, oil rigs, pipelines, bridges and so many other metal objects. This is because if any metal meets water, it will start to rust over time especially without the proper protection.
This method employs two different type of metals; the metal we would like to protect and a sacrificial anode. A sacrificial anode is an anode that is the intended target of destruction instead of the metal it serves to protect. The sacrificial anode may get rusted sometimes, and at that point, it gives off small particles named electron. These electrons travel to the metal we wish to protect and aid in its safekeeping. This process is very good because it does not break the material by itself and keeping the strength of the metal.
Essentially instead of putting zinc on your metal, you are mating it with another more reactive metal that will rust away before your object. This is the basics behind a sacrificial anode cathodic protection system. Metals love to rust so they attract one another; however, the sacrificial anodes are metals that are meant to rust first before anything else begin to ever get rust.
Now, if the wants to protect metal of both of them is put inside water, the one needing the protection will start rust from now. Sadly, though they would just rust even faster than the sacrificial anode. So, the anode helps to attract the rust away from the metal we are hoping to preserve. Rather than key metal corroding, the anode itself corrodes. This is a method of cathodic protection at work, and it works very well in most cases, particularly if the metal structure is submerged in water.
The use of sacrificial anode cathodic protection is not only a smart idea to protect metals but also very cost-effective. It helps metal structure to have longer life due to which the repairs and maintenance become expensive. Doing that could save an expensive shutdown or stoppage of work the metal structures were to fail, and that can particularly benefit businesses.
