A Study of Natural Coatings as Corrosion Inhibitors for Metal Surfaces

This study investigates the effectiveness of natural coatings derived from turmeric, ginger, aloe vera, and curry leaves, individually mixed with carboxymethyl cellulose (CMC) as a binding agent, in reducing corrosion on metal surfaces. The coated metal samples were air-dried and exposed to hydrochloric acid (HCl) to analyse their corrosion resistance properties. The observations, including weight loss measurements and visual inspections, demonstrate the efficiency of these natural inhibitors. The findings contribute to the development of sustainable and environmentally friendly corrosion prevention techniques.
