Eco-Friendly Roselle (Hibiscus Sabdariffa) Leaf Extract as Naturally Corrosion Inhibitor for Cu-Zn Alloy in 1M HNO3
نویسندگان
چکیده
The eco-friendly compounds especially plant extracts have emerged as green corrosion inhibitors for metals and alloys. inhibiting impact of Roselle extract on Cu-Zn alloy in 1M HNO3 solution was studied by weight loss, electrochemical impedance spectroscopy (EIS), potentiodynamic polarization (PDP). It found that acts a good mixed-type inhibitor acid solution. rate decreases with increasing the concentration increases raising temperature. formation protecting film surface presence confirmed scanning electron microscopy (SEM), energy-dispersive X-ray (EDX). high inhibition efficiency 94.89 % recorded 80% There are agreements between results from all techniques.
