Corrosion control is a costly and persistent problem across every class of surface ship, and as ships age, the maintenance costs and effort required to extend their service lives increases. Paint coatings have holidays, low abrasion resistance and poor bond strength. Corrosion initiated at scratches and holes easily lifts the paint film, accelerating attack of the underlying steel. Paint over corrosion only masks an ongoing problem. In contrast, metallic zinc coatings have excellent abrasion resistance and superior bond strength. Furthermore, metallic zinc coatings offer both barrier protection and cathodic protection to steel. The ultimate corrosion protection is to use a metallic zinc base layer with a paint topcoat. The paint adds an extra layer of barrier protection to the zinc, while the zinc protects the paint from underfilm corrosion at scratches and holes. Effective corrosion control significantly reduces maintenance costs and provides the lowest cost of ownership for a vessel. Application of metallic zinc coatings for steel ships will be presented with case studies.

Key words: Duplex coatings, Hot dip galvanizing, Thermal sprayed zinc, Corrosion, Ships
