Effect of surface roughness on corrosion behavior for carbon steel was coated by metallic layers Cu- Ni Reinforced with Gr layers. Surface finishing P320, P600 and P1200 mesh used until a mirror shiny surface before metallic coated with Gr layers at consecrations 0.25, 0.5, 1and 2 g/l of Gr. First, X-ray diffraction), electron microscopy associated for carbon steel & Gr and Microscopic test for coated specimens. The techniques were performed to study the effect of saline water (3.5%) on the corrosion behaviors, Open circuit potential, Tafel polarization and impedance spectroscopy tests. At P320 Equivalent Circuit elements were decreasing but, Corrosion reaction’s Rp was increased at 5 min and 0.25 g/l. And also, coating’s Rpore with Electrolyte’s Ru were increasing at 30 min for 0.5 g/l, and also coating’s Rpore and Electrolyte’s Ru were increased at 20 min for 1 g/l, At P600 ECE’s were decreasing but, corrosion reaction’s Rp was increased at 30 min 1 g/l, and also, coating’s Rpore and Electrolyte’s Ru were increased at 20 min for 1 g/l, and At P1200 ECE’s were decreasing but, Coating’s Ccoat was increased at 5 min 0.25 g/l, and also coating’s Rpore and Electrolyte’s Ru were increased at 0.5g/l, 30 min.

The study was an experimental investigation for time 10, 20, 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, scanning electron microscopy associated for carbon steel & graphene and Microscopic test for coated specimens. The techniques were performed to study effect of saline water (3.5%) on the corrosion behaviors. Open circuit potential, tafel polarization, cyclic potentiodynamic polarization and impedance.The results revealed that the types of corrosion were pitting corrosion, where the highest protections against corrosion were at 20 min with concentration 1 g/L graphene coating with P600 and P320 mesh. The results also showed the time increasing led to increasing for protection efficiency, decreasing for corrosion rates, increasing for polarization resistance, and decreasing for porosity percentage. Between metallic layers coating reinforced with concentrations 0.25, 0.5, 1and 2 g/l graphene.

Atomic Layers of Graphene for Microbial Corrosion Prevention

Graphene is a promising material for many biointerface applications in engineering, medical, and lifescience domains. Here, we explore the protection ability of graphene atomic layers to metals exposed to aggressive sulfatereducing bacteria implicated in corrosion. Although the graphene layers on copper (Cu) surfaces did not prevent the bacterial attachment and biofilm growth, they effectively restricted the biogenic sulfide attack. Interestingly, singlelayered graphene (SLG) worsened the biogenic sulfide attack by 5-fold compared to bare Cu. In contrast, multilayered graphene (MLG) on Cu restricted the attack by 10-fold and 1.4-fold compared to SLG-Cu and bare Cu, respectively. We combined experimental and computational studies to discern the anomalous behavior of SLG-Cu compared to MLG-Cu. We also report that MLG on Ni offers superior protection ability compared to SLG. Finally, we demonstrate the effect of defects, including double vacancy defects and grain boundaries on the protection ability of atomic graphene layers.
