The direct economic cost for corrosion mitigation include the costs for labor and preparation of coating or any traditional method of corrosion mitigation while, there are also a large number of indirect economic costs associated with corrosion, which include plant downtime, loss of product, loss of efficiency, contamination and overdesign. These costs are harder to estimate and they may even have a larger impact than direct costs. Besides economic costs, corrosion also takes a significant toll on human life and safety.

Self-healing technologies which heal either autonomously or by applying some external conditions could significantly increase material/system reliability, reduce life cycle costs, and improve operational safety.

Corrosion resistant self healing coating is the best possible way to find a solution for making a coating which prevents rusting & even heals itself upon getting damaged thereby increasing its lifecycle & reducing the overall cost. Microencapsulation is a process for this purpose where capsules of certain sizes are used. The stabilizer is the outermost layer of capsule filled with healing agent which on cracking polymerizes & hence justifying it’s working.

The hypothesis of considering a composite of GO & PF as a stabilizer improves tribological properties. Upon simulation we wished to convey self healing coating without any intervention to heal both surface scratches & mesoscopic damage. Acrolein formation brought about a change in the reaction of coating Various factors like temperature, pH etc. have a specific range to form the desired coating. This cost effective coating finds its applications in spacecrafts, nuclear reactors where it is environment friendly without utilizing a catalyst.
