PERFORMANCE OF SELECTED METALLIZED COATINGS AND SEALERS ON LOCK AND DAM FACILITIES

An evaluation of the performance of eight metal coatings and sealers used in the maintenance of lock and dam structures in the Ohio River is reported. The criteria used to select coatings and sealers for the evaluation are outlined, and the application procedures for each material are explained. The field evaluation of the materials used, and the results of the evaluation procedure are discussed. The coating and sealer systems studied are as follows: four thermal spray materials including aluminum bronze; stainless steel; zinc-aluminum; and pure zinc; three sealer systems including corps Specification V-766E, vinyl acetate-vinyl chloride copolymer; specification Mil-P-24441, epoxy polyamide; and Steel Structures Painting Council Paint 27 vinyl butyral wash primer, SSPC Paint 9 vinyl intermediate coat, and V-766E topcoat, and SSPC Paint27 vinyl butyral. It was concluded that coatings anodic to mild steel appear to offer an alternative to conventional paint coatings for use in abrasion-corrosion environments. Coatings cathodic to mild steel such as stainless steel and aluminum-bronze, should not be used in fresh water immersion, where exclusion of water to the substrate cannot be guranteed.
