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 …

Oil lubricating tribology And additives for lubricating oil
Abstract: Numerous goods that are characterised by hundreds of basic chemicals and additions fall under the umbrella phrase "lubricating oil." Lubricating oils can either be synthetic or mineral-based. This article focuses on petroleum-based lubricating oils, which are composed of 80–90% petroleum hydrocarbon distillates and 10–20% additives and are used to lubricate a variety of internal combustion engines. Lubricating oil exposure occurs mostly through inhalation and skin contact in both occupational and …
