N2 - Improving the corrosion resistance of carbon steel is of great importance to realize widely use in various industries. The anti-corrosion coating is a significant protective strategy. Therefore, uniform aluminum coatings (AlOx-CS), electrodepositing in ionic liquid electrolyte at room temperature, was developed to enhance corrosion resistance of carbon steel. The lower part of the electrode has a better distribution uniformity than the upper part of the electrode, and the distribution of a line has the lowest variance. The uniform AlOx-CS coating is the most corrosion resistant due to sealed Al2O3 layers. The corrosion rate of the AlOx-CS coating is 0.4 mm a−1. The self-corrosion current density of AlOx-CS coating is 34.4 μA cm−2, nearly 2 times compared with pristine carbon steel. The impedance value with AlOx-CS coating is increased by nearly 300 times compared with pristine carbon steel. The morphology and composition of aluminum-based reinforced coatings had no significant changes in atmospheric exposure, 3.5 pct NaCl salt spray and 3.5 pct NaCl immersion environments. The aluminum-based reinforced coatings can enhance the lifespan of carbon steel materials, while also reducing economic losses and safety hazards.
