Study and Computational Simulation of Nanomaterial Coating to Reduce Crevice Corrosion

The crevice correction is a common type of localized corrosion which costs multibillion dollar losses in many different fields including aerospace, automobile, and building structures. The crevice geometry can easily catch moisture and impurity which accelerates the chemical corrosion. It is one of the dangerous corrosions that can cause sudden failure of the products and involve the human injury in some cases. Nanomaterial coating can disperse extremely tiny platelets into the crevice geometrical surfaces and make much strong and durable material coating to significantly reduce the crevice corrosion. This paper focuses on reducing the crevice corrosion damage by introducing the computer-aided modeling and simulation of nanomaterial coating on crevice structure to verify the nano-coating performance. The sample experiment to prove the strong anti-corrosion of nano-coating on crevice structure has also been performed to compare with the computational simulation results. Both results show that the nano-coating has much strong anti-corrosion performance over currently existing anti-corrosion coating techniques.
