Mitigating Pipeline Corrosion Using A Smart Thermal Spraying Coating System

Corrosion is recognized as one major reason for the failures of on-shore underground steel pipes, which results in increase in maintenance cost and system downtime. To mitigate corrosion, a common method is to combine cathodic protection and coating techniques such as polymeric and metallic coatings. Polymeric coatings dominate the coating techniques due to their good performance on separating metal from the surrounding corrosive environments. However, corrosion may still develop beneath the polymeric coatings in random locations. In these circumstances, a strong metallic coating from high corrosive resistant materials deposited by thermal spraying techniques can be considered as a potential cost-effective alternative. These coatings can separate pipes from surrounding environments and meanwhile exhibit cathodic protection properties.
