Anti-corrosion behaviour of barrier, electrochemical and self-healing fillers in polymer coatings for carbon steel in a saline environment
MetadataShow full item record
Coatings serve many purposes on metallic surfaces, including tribological coating, anti-static coating, electromagnetic shielding coating, anti-reflective coating, and anti-corrosion. Polymer coatings for corrosion protection of metallic substrates are mostly related to long-term performance needs. In addition to the barrier effect, thecoating must have the ability to inhibit the corrosion process if the protective barrier is disrupted. Incorporating fillers, such as metallic oxides, layered fillers and conducting polymer, improves long termed anti-corrosion along with barrier, mechanical, ...
