Corrosion behavior of modified nano carbon black/epoxy coating in accelerated conditions

- By using SDS as a surfactant, nano particles of CB were uniformly dispersed.
- CB nanoparticle in the epoxy coating improved the corrosion resistance of the coating.
- By addition of CB nanoparticles to the epoxy diffusion ions and water became limited.
- The dominance of barrier mechanism was proved by calculation of the diffusion coefficients.
