Abstract

Numerous failures and losses in the manufacturing and chemical industries have been attributed to corrosion processes. Chemical inhibitors can be used to combat failures brought on by metals that can no longer support the designed load due to corrosion problems. Synthetic inhibitors work well, but they come with drawbacks, including toxicity, disposal issues, lawsuits, and exorbitant costs. To safeguard people, the environment, and money, green inhibitors have gained popularity as partial and full replacements for chemical inhibitors. However, more investigation into the metal-inhibitor-media combination that yields the best results is needed because inhibitors are environment-specific. There are many effects of corrosion, and they are frequently more severe than a mere loss of metal mass when it comes to the equipment's or a structure's ability to work safely, dependably, and efficiently. The purpose of this study is to evaluate the Neem leaf's anticorrosion capacity against mild steel corrosion. The experimental work was done using the weight loss method. According to the weight loss values obtained, the corrosion rates drastically increased for the controlled experiment (acidic media without leaf extract), but there was a corresponding drop in corrosion rates when different doses of the leaf extract were added to the acidic medium, indicating that the neem leaf extract was protecting the metal. Corrosion rates tend to decrease as inhibitor concentration rises, with a dose of 0.5g/L achieving the highest level of 86% inhibitory efficiency. The Azadirachta Indica Leaf Extract showed favorable inhibitory effects on mild steel, demonstrating that when used in the proper proportion, it will increase the service life of mild steel in sulphuric acid environments.

There are many effects of corrosion, and they are frequently more severe than a mere loss of metal mass when it comes to the equipment's or a structure's ability to work safely, dependably, and efficiently. The purpose of this study is to evaluate the Neem leaf's anticorrosion capacity against mild steel corrosion. The experimental work was done using the weight loss method. According to the weight loss values obtained, the corrosion rates drastically increased for the controlled experiment (acidic media without leaf extract), but there was a corresponding drop in corrosion rates when different doses of the leaf extract were added to the acidic medium, indicating that the neem leaf extract was protecting the metal. Corrosion rates tend to decrease as inhibitor concentration rises, with a dose of 0.5g/L achieving the highest level of 86% inhibitory efficiency. The Azadirachta Indica Leaf Extract showed favorable inhibitory effects on mild steel, demonstrating that when used in the proper proportion, it will increase the service life of mild steel in sulphuric acid environments.
