Corrosion - the bane of all the industries

Image
By

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 Fe2O3, Fe3O4, FeCl3 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 Fe2O3 and Fe3O4.

And that is how the corrosion of steel begins.

What is a Corrosion Loop - PART 2 - EXAMPLE

By
How to prepare a corrosion loop? To prepare a corrosion loop, the person in charge will look at the overall picture and answer the following questions - 1. What is the process? 2. What are the components? 3. What are the materials for each component? 4. What are the common features among them? 5. Where does the commonality end? -  This is important as that will mark the beginning of a new corrosion loop. 6. Can I use the same inspection procedure for all of them? 7. Do they corrode/get damaged in the same manner due to the same reasons? WATCH THE VIDEO FOR A DETAILED EXPLANATION -       Read part 1 here! https://corrospective.com/ 😀Happy learning! 😀

Need of 'CORROSION PLANNING'

By
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...

Thesis flowchart...aka...How to decide what to write first in your thesis?

By
It was that moment in my thesis writing when I had received a terrible feedback and was asked to overhaul the entire document. It was time to take a break from the screen and go back to basics. I printed out my document and went home. Then I took a break that evening, because it is one of the most underrated but essential things to get everything into perspective. The next day I proceeded to lay out the pages of my thesis chapter-wise on the table. Then I took a blank paper and pad. I thought, "How will I explain my work to my family members in my native language?" So I decided to write down my work in my native language in the form of an algorithm and then rearrange my thesis. I answered the following questions to do so - What is the issue? Where is it encountered? Is it very common? What makes it so very important? What are the steps that people have already taken to solve it? Why have they not been that effective? What is it that I did to solve the issue? How did I do it? ...
