| Abstract: |
Metallic zinc coatings are recognized as environmentally friendly, sustainable, and low maintenance, providing the lowest life cycle cost corrosion protection. Various case studies illustrate that the corrosion protection of steel bridges with thermal spray zinc (TSZ) duplex coating are very good in the environmental corrosivity of class 4 or 5 without any maintenance for a long time. Meanwhile, TSZ coatings on the exposed surface of the concrete of reinforced concrete structures can be electrically connected to the steel reinforcement and provide corrosion protection to the steel. The lives of iconic bridges have been successfully extended by using TSZ coatings for use as anodes in ICCP systems. |
