Abstract

The surface defects of the material are difficult to detect and difficult to repair. A big challenge in materials science is to design „smart“ synthetic systems that can re-establish the continuity and integrity of the damaged area. Recent research of the nanocontainers with the process of self-healing materials promises a good avenue for new smart nanocoating interfaces. We use continuum modeling approach to investigate coating substrates that contain nanoscale defects with healing agents. Here we use Finite Element Method (FEM) with different diffusivity and fluxes.  The fitting procedure from simulations is performed to determine diffusion coefficient and the diameter of nanocontainers to match experimental results. We also show the risk map from the calculations of the creepage and coverage.
