A Comparative Study of Neem Oil and Mahogany Oil as Corrosion Inhibitors for Mild Steel Exposed to Hydrochloric Acid
Abstract: Corrosion is essentially an oxidation process, wherein the oxidizing agent itself undergoes reduction due to the influence of corrosion agents like salt, air, or moisture. Metals and their alloys naturally tend to react spontaneously with their surroundings, leading to a detrimental impact on their mechanical and physical properties. This project aimed to evaluate the effectiveness of two different oils, namely neem oil and mahogany oil, as agents to prevent acid …
