Comparative study of corrosion behavior of Aluminum, Zinc and Babbit coatings deposited by Value Arc Technique for protection of subsea structures

Steel structures are significantly degrades owing to corrosion especially in sea water environments. To mitigate the corrosion problem of steel used in sea water environments by the application of sacrificial metallic coatings (such as Aluminum, Zinc and alloys). In the current study, the corrosion behavior of Al, Zinc and Babbit coating deposited by value arc technique was observed by electrochemical measurements and immersion of coatings for 10 weeks in 3.5% NaCl solution. The results show that zinc and aluminum coatings are best solution for protection of steel structures from corrosion in submarine environments being utilized as sacrificial anodic coatings.
