Metals and Another Passion

An unexpected passion

I knew I would like the paper. It’s title signaled to me, answers to questions I have long asked myself and others. My fascination with corrosion and metals stem from a desire to see industrial parts and machinery be a sound investment for islands like my own. When you are surrounded  by  the sea, the salt in the atmosphere clings and leaves its presence on metal surfaces, causing deterioration, rusting and compromised metal integrity. This can cause accidents and losses in equity when equipment purchased, does not ‘stand up’ to the ‘island test’.
The atmosphere in the Caribbean islands will have a higher salt content as our size is not significant when compared to the huge land masses in countries such as the United States of America or Europe and Australia to name a few. It is a familiar sight to see welded joints or machine fabricated points of contact rusting in industrial equipment. Though many motors may come sealed with a protective covering based on acceptable standards, on many occasions,it simply slows deterioration. There are coatings which can be ordered with products but these are add-on’s and will last for a specific period, eventually breaking/ flaking away. From a layman perspective, this means predicting depreciation values based on local conditions and not necessarily on manufacturers warranty as per usage.


I like the look of smooth metal  industrial extractor fans. I like the sound of each surface based on its thickness and iron content. If you give a gentle knock on a metal surface it makes a sound. Some large metal industrial fans can sound dense when tapped. It’s a combination of the product specifications, motor, and the conditions of use together with product design which result in the overall sound. Axial fans tend to have a deep sound, but some can be high pitched in my opinion. The centrifugal fans, based on the shape and location tend to be less noisy, but sound can be controlled based on installation and ancillary products used. Domestic fans for home use tend to be relatively quiet, and are available in beautiful designs, all aesthetically pleasing!
For over 11 years  ventilation and  extractor fans with these beautiful propellers to move air have become significant to me. They extract hot, foul, stale, contaminated air and bring in air from the outside ( hopefully filtered!). Powerful. Dynamic. Strong pieces of engineered ventilation solutions, which can help to enhance the quality of the home or work environment. It is necessary in this industrialized world to think about air quality and its impact on work environments. A follow up post on basic ventilation and its impact in commercial applications will be published soon.
This is a  different world where my passion for adequate ventilation to be available and in all buildings matter. Building safety and building codes are still being compromised in many countries. Sometimes its not deliberate, simply a lack of awareness and understanding. As technology becomes available and incorporated into designs, product integrity and performance will be impacted by research and its improvement on existing products. People, buildings and products need a balanced environment to thrive and breathe! We need fans, pun intended!
I enjoyed the peer reviewed article by Milos Djukic and his colleagues on Hydrogen Embrittlement of Industrial Components: Prediction, Prevention and Models. It took me back to a few years ago, and the excitement of working with ‘fans’ and their effectiveness in commercial settings.  I see things differently, and enjoy learning about findings which will enhance product offerings. This is not a scientific discussion from me, but has added more fuel to a subject area which is fascinating. Understanding ‘why’ is always a great place to start.
Thank you for reading, I hope you enjoy my discovery of this article on corrosion and will check it out.
You can also share with me on Facebook and Twitter. I like hearing from you!
