Corrosion - the bane of all the industries

Corrosion is the journey of an element from its most active form to its most stable form.  The birth At the place of its birth, inside the earth, an element such as iron comes into contact with atmospheric oxygen, chlorides, sulphate, and moisture. and is quite happy to remain in peace with them in the form of Fe 2 O 3 , Fe 3 O 4 , FeCl 3 and such. The growth It is then extracted and made to go through a number of processes which separate it from the ions and bring it to its elemental form. It is then put into use to make steel, where it coexists with carbon, manganese, chromium, and other alloying elements. The interaction However, iron has three electrons that it desperately need to give away. That is exactly what it does the moment the steel is brought out from the factory and put outside in the shed. Iron is more than happy to reunite with its old buddies - oxygen and moisture. It gladly gives away its electrons to them and returns to its peaceful state of Fe 2 O 3...

Types of MARINE corrosion

Types of MARINE corrosion The marine environment is one of the most corrosive environments.  Its corrosivity is due to the ionic concentration of the seas and oceans, temperature variations, wind velocities, depth of the sea, and biological elements. As a result, the corrosion on marine structures such as ships, FPSO, and offshore platforms, appears in multiple forms. Hence, it is important to learn about the basic types of corrosion as applicable to the marine environment. Some of these types of corrosion in a marine environment are - Uniform corrosion due to sodium, magnesium, and calcium salts Uniform corrosion is characterized by the removal of the material all over the surface. It leads to thinning of the walls. Pitting in active-passive alloys such as aluminium Active-passive alloys have a thin oxide film on the surface. A small break due to the chlorides in the seawater allows the penetration of the water and ions, leading to pit formation. Crevice corrosion in fixtures and ...

Need of 'CORROSION PLANNING'

Need for 'CORROSION PLANNING'  The importance of material selection cannot be stressed enough. With the equipment comes the material of the equipment, and every material is prone to corrosion in some way. For most fields such as defence, oil and gas, automotive, and marine, the qualification tests for the material selection begin and stop with the mechanical properties and composition. There is not even a mention of the possible corrosion phenomena for that particular material. This results in 'surprises' when there is a serious failure. Only after that are the corrosion investigations carried out and modifications done. However, by that time, it may be too late for some. Hence, it is necessary that the concerned personnel in the industries do not cut costs where corrosion is known to be an issue. What is Corrosion Planning? It is critical to begin a "CORROSION PLANNING" to ensure that the corrosion risks of every material that is qualified, and every componen...
