ABSTRACT:
A combination thermally sprayed antifouling metal coating and seal coat on a marine surface and a method of preparing the same. The method comprises the steps of applying a resin coating on the marine surface, and thermally spraying molten metal particles on the resin coating to impinge and interlock with the resin coating and form one or more metal layers. The resin may be wet during the thermal spraying or be filled with hollow beads and spheres which are ruptured after curing to form locking sites for the metal coating. A seal overcoat is applied to the last one of the one or more metal layers. The seal overcoat when applied has low surface tension to permit wetting and penetration of the outer one of the one or more metal coatings, leveling and flattening properties to produce a smooth finish on the more metal coatings, thixotropic properties, abalative properties, and a high copper oxide content for antifouling.
