When you think of corrosion, you probably imagine a smelly process and something unsavoury. The reality is much different than what we had imagined. Instead, we now know that this happens all of the time and is an essential process. We just did not know that it was called corrosion until now. Still, it is surprising to see just how much of an impact this has on our lives. Take a look at these 7 Facts About Corrosion that You Should Know to get an idea of this invisible and essential process.
What Causes Corrosion?
Corrosion, also called electro-chemical corrosion, is a process in which one material reacts with another through an electrical charge. It is the result of an electrochemical reaction that occurs at the interface between dissimilar metals. Electrochemical corrosion occurs in water, air, soil and other media. There are three steps to corrosion: a biological or chemical reaction at the interface between the dissimilar metals, a transfer of electrons at the interface, and a change in the macroscopic properties at the interface.
What is Salt corrosion?
Salt corrosion occurs in aqueous media and is caused by the reaction of a soluble salt with a metal. Salts, such as sodium chloride (NaCl), react with metals, such as iron and steel, to form insoluble salts that are called chloride compounds. These are generally soluble in water and will attract more water. This process creates a film of salt on the metal surface which then acts as a catalyst for further corrosion. Because the chloride ions are not soluble in the polymer of plastics, they cause an electrochemical reaction that causes the polymer to break down, yielding a black surface layer that interferes with the polymer’s optical properties and mechanical properties.
How does rusting happen?
When iron is exposed to oxygen and moisture, it rusted. The rusting process occurs when oxygen combines with the carbon in the iron, giving off heat as a byproduct. The heat causes the iron to expand and contract, causing it to lose electrons. The iron becomes an anode, and the oxygen combines with the carbon in the iron to form carbon dioxide and water.
The Role of Electrolytes
During galvanic corrosion, an anode (such as a metal wire) and a cathode (such as a metal to which water is attracted) are connected. When two different types of metals are connected in this fashion, an electrical current is generated and the two metals are oxidised. In this case, iron and steel are the anode and cathode, respectively. Oxygen from the air is attracted to the anode, combining with it to form the compound hydroxide. This compound, in turn, attracts water, which combines with the rest of the compound to form a solution called electrolyte.
Corrosion in Everyday Life
Corrosion problems may take place in many different places: in bridges, boilers, pipes, turbines, ships, cars, homes, and many other places. It has been estimated that an average of 30% of the United States’ infrastructure is affected by corrosion. This may be due to the fact that corrosion problems may take place in many different places: in bridges, boilers, pipes, turbines, ships, cars, homes, and many other places. It has been estimated that an average of 30% of the United States’ infrastructure is affected by corrosion. This may be due to the fact that much of our infrastructure is made from steel and iron, which are metals that are susceptible to corrosion.
Weird but True: Corrosion in the Ocean
During a study in the South Pacific, researchers dropped a steel ball into the water and watched as it sank in. The ball was resting on a sea bed of rust. The bottom of the sea bed was covered with rust, and the researchers believed that it was the rust that was keeping the ball in place. The rust prevented the steel ball from pushing into the sea bed. This is an example of salt-loving steel. The steel likes the presence of salt and will arise along coasts that have a large amount of salt in their soil.

Conclusion
There you have it, these are some of the most surprising facts about corrosion that you need to know. Corrosion occurs in all sorts of places, from bridges to boilers, and even in the ocean. It is an essential process that we just didn’t know about. Despite how surprising it may be, corrosion plays an important role in our everyday lives. Now you know just how essential it is.
