Sustainable Corrosion Mitigation Using Aqueous Spent Coffee Grounds Extract: Comparative Performance in Different Acidic Media

This study investigates the efficiency of green corrosion inhibitors derived from spent coffee grounds (SCGs) for OL 37 carbon steel in 0.5 M H2SO4 and 1 M HCl environments. The aqueous extracts, labeled K1 and K2, were obtained through specialized extraction techniques and chara...
