Corrosion Inhibitation

One of the solutions to prevent corrosion or mitigate the effects of this phenomenon is to use superhydrophobic surfaces. Superhydrophobic surfaces are surfaces with contact angles larger than 150° and low contact angle hysteresis, which are highly regarded recently, due to their unique properties, such as rapid drop slip on them, which reduces the corrosion effect. Using surface nano-engineering we can produce these surfaces. Upon formation, drops on these surfaces slide. So the duration of exposure to corrosive drops (e.g. water or sulfuric acid) reduces greatly. Also, because of nano structures and air filled cavities on these superhydrophobic surfaces, the solid-droplet contact area can be reduced up to 90%. So these two effects (low contact duration and low contact area) with super-hydrophobic coatings on metal surfaces, can increase corrosion resistance to a considerable extent.

The final output of the project is to achieve a specific method for the use of these technology to reduce the corrosion of metals. It is also possible that studies and experiments are focused on a specific application (Like corrosion of carbon steel used in the power plant equipment). Therefore, the achievement that comes at the end of the project, is utilization of superhydrophobic surfaces technology that one of its applications is to reduce corrosion.
