Synthesis of a Sustainable Acidified Metallic Halide Solution with Aluminium Oxide for Brass Corrosion Inhibition

Abstract:

This study proposes the use of an innovative acidified metallic halide solution to address brass corrosion. The research identifies key parameters that contribute to corrosion and demonstrates that the new solution can effectively restore oxidized brass surfaces, serving as a simple and safer alternative corrosion inhibitor. The formulated solution consists of a metallic halide, an organic acid, and alumina as an abrasive. The metallic halide functions as an oxidation inhibitor, preventing the formation of copper (I) oxide (Cu₂O) and zinc oxide (ZnO). Analytical results confirmed the effectiveness of the treatment solution. FTIR spectroscopy showed reduced oxide formation, while EDX revealed a lower oxygen signal and the presence of iodine, indicating successful corrosion inhibition and surface modification. SEM images demonstrated significant surface improvement after treatment, with reduced pitting and oxidation compared to the corroded sample. Contact angle measurements confirmed that treated surfaces transitioned from hydrophilic to hydrophobic states, indicating successful restoration. This process offers a practical, efficient, and safer corrosion mitigation method for brass, addressing a critical need for metal manufacturers and suppliers.
