Even though corrosion inhibitors come in a variety of ways, natural source-based corrosion inhibitors, also known as green corrosion inhibitors, have acquired reputation due to their low toxicity, availability, and minimal cost of production.

Fremont, CA : Steel is one of the most commonly used alloys because of its first-grade mechanical properties. These properties consist of malleability, ductility, great strength, and mouldability. The most utilized steel alloys are carbon steel and mid steel. The top steel consumers in various forms are process constituents, raw material, and equipment production for cars, shipbuilding, architecture, petrochemical, and metallurgy. Apart from the above, the other biggest user is construction.

What all these areas of application have in common is the risk of steel corrosion. Also, research has shown that corrosion causes vulnerability, changes in surface properties, and reduces the effectiveness of metal usage in industrial processes. Therefore it is suggested to continuously monitor it. Corrosion inhibition and prevention are two different capabilities, with the first one being the more widely used. Corrosion inhibition is a procedure of safeguarding a surface against electrochemical processes by using synthetic or natural chemicals. Corrosion inhibitors are mostly employed in the petroleum industry to hinder corrosion induced by acidic gases. Even though corrosion inhibitors come in a variety of ways, natural sources-based corrosion inhibitors, also known as green corrosion inhibitors, have acquired reputation due to their low toxicity, availability, and minimal cost of production.

In spite of detailed studies being done, some things are still left to be explored. A significant aspect is the study of the impacts of extreme environments such as high temperatures. Additionally, tests such as thermogravimetric analysis should be carried out to demonstrate the feasibility under exothermic settings. Green corrosion inhibitor applications should be investigated in a gaseous atmosphere. In short, sustainable means for avoiding steel corrosion have been the centre of focus for quite some time and the recent study has discussed essential aspects in this regard that would be fruitful in increasing the lifetime of such alloys and defending them from rust and corrosion.
