Epoxy coating is one of the most common corrosion mitigation methods to protect metal substrates from water, dissolved oxygen, and corrosive ions. However, there is limited research conducted on the coatings on the additively manufactured (AM’d) metals. In this work, the epoxy coating was applied on the surface of AM’d 316L SS samples. To explore the interfacial properties, the bond strength was tested on the interface between the coating layer and 316L SS samples, and the corrosion properties were also explored with both coated samples and AM’s samples. To explore the fracture mechanism of the interfacial bond, a molecular dynamics (MD) model was built to simulate the interface between the polymer and metal. The simulated pull-off test was conducted to evaluate the mechanical properties and failure mechanics on the interface. This study provides important information for extending the AM metals in applications where corrosion resistance is required.
