Abstract
The study was an experimental investigation for Time 10 min, 20 min, and 30 min effect of graphene coating in between metallic layers of Copper-Nickel on corrosion behavior for carbon steel in saline water. And Surface finishing for substrates was P320, P600, and P1200 mesh until a mirror shiny surface before coated by metallic layers Cu – Cu – Ni reinforced with concentrations 0.25, 0.5, 1and 2 g/L graphene. First, X-ray diffraction (XRD), electron microscopy (SEM) associated with carbon steel & graphene, and Microscopic test for coated specimens. The techniques were performed to study the effect of saline water (3.5%) on corrosion behaviors. Open circuit potential Eoc, Tafel polarization, cyclic potentiodynamic polarization, and impedance spectroscopy EIS tests.
The types of corrosion were pitting corrosion, where the highest protection against corrosion was at 20 min with concentration 1 g/L graphene coating with P600 and P320 mesh.
The time increasing led to increasing in Protection Efficiency (PE%), decreasing for Corrosion Rates (mpy), increasing for Polarization Resistance (Rp), and decreasing for Porosity Percentage (PP%).Between metallic layers coating reinforced with concentrations 0.25, 0.5, 1and 2 g/L graphene.
