All of us corrosion people head out of the house to work on coatings. And yet, we leave so many types of coatings behind in our house. The most commonly seen commodity is an electric box with switches. Usually they are coated.  This is an example of such an electric box. It shows blisters formed in the white coating. Such blistering occurs when water penetrates the pores in the coating.  Usually such parts do not come under the 'critical' category. Hence, the coatings are not very thick. Moreover, there is no coating inspector involved during the application. As a result, they are prone to early degradation. However, their position plays an important role in determining this time frame. Those boxes present outside the hose are exposed to the heat and cold. Usually they will be in a shaded area. So, they may not face the rain directly. Some boxes are inside the house in rooms. Those face the least coating damage. The image above is from an electric box in a bathroom...

Practice, practice, practice... and you shall gain the certificate! So here goes a new series, where I will post quizzes on various corrosion and coating topics. This is for anyone who likes quizzes, and ESPECIALLY for those attempting exams! So here goes the first one!  Subscribe to this blog for updates!  Loading…

I am someone who loves to study. This may sound 'nerdy'. In fact, someone called me that once. I was almost 22 and even then I was OFFENDED. Hah! This is something so many of us have struggled with. In fact, just to not be a 'nerd', there are people who have simply stopped studying as much as they used to. After all 'OMG, you study so much!' is not really 'cool' after a certain age. Not anymore! I have learned that everyone is 'nerdy' in their own way, even those who pride themselves of being 'laid back' and proceed to call others 'nerds'.  So, here's to you, the sports lover. YES, I am looking at you. If you can mouth off the statistics for your favourite team, you are a nerd, only a sports one. In fact when I get hold of a magazine for corrosion, I have to take a deep breath and choose which article to read. Obviously, I want to read all the articles at once! There is so much to learn, especially in terms of scie...

When I began to conduct online courses for corrosion and coatings, I had participants who eagerly attended them. However, there were many who could not find the time due to their professional and personal commitments. On my end, I was unable to conduct sessions for more than one hour everyday due to my commitments.      As a result, I was left with a feeling that I should do something more to share corrosion with others. This led to me to starting my website.      After numerous difficulties, I was able to get it up and running.      I am pleased to announce that https://corrospective.com is LIVE!      This website is based on two main qualities -EASE and FLEXIBILITY EASE of access and learning FLEXIBILITY of time and requirements Here are a few FAQS below- What is it? It is a website with online courses available for purchase. When I access them? Once you buy a course, you can access it anytime! How do I know if it is good ...

Corrosion in daily life - Steel frames Looking at LinkedIn, corrosion may feel like an extremely intricate issue seen in large industries. However, looking around, we can see corrosion everywhere! Where was this photo taken? The photo above is of a steel frame attached to a balcony.  The part shown here is the bottom part of the frame. The coatings for such steel parts usually serve the purpose of moderate corrosion protection and more of aesthetics. If you observe, the thickness of the coatings also does not seem to be a lot. Why did the coating degrade? When it rains, the rainwater collects on the bottom of the frames.  This degrades the coating. At the places where it is not perfect anyway, the underlying steel is free to corrode. Most importantly, corrosion is more severe at the edges. It is severe enough to chip off the material entirely. That point is a prime site for crack formation and breaking of the frame. Have you seen such corrosion in your balcony fram...

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...
