Abstract

A process of protecting a ferrous article comprises treating the article with a solution to cause the formation of a phosphate coating on the surface thereof, the resulting phosphated surface being subsequently coated with a fused polyester resin. After the formation of the phosphate coating, the article is dried and heated, and the heated article is immersed in the dense phase of a fluidised bed of polyester resin particles whilst the article is at a temperature high enough to cause fusion of the contacting resin particles whilst being below the decomposition temperature thereof, the heated article being kept immersed until a layer of resin of desired thickness is formed on its surface, the coating of resin particles being allowed to fuse to form a continuous resinous coating before the coated article is cooled. The resin may also be applied by the electrostatic powder coating process, the cyclone process or the flame spraying process. The phosphate coating may be zinc phosphate in amorphous or microcrystalline form. The article having the phosphate and fused resin coating may be made electronegative with the respective surroundings and may be caused to form an electrode of an electrolytic cell or may be connected to an external source of electromotive force. The article may be of iron, iron alloy or steel, and may take the form of a pipe, sheet, rod, or casting. The polyester may be a fusion blend of ethylene terephthalate-neopentyl terephthalate copolyester and a copolyester of ethylene glycol, neopentyl glycol, terephthalic acid and sebacic acid, polyesters and copolyesters of terephthalic acid, bibenzoic acid, the naphthalene dicarboxylic acids with glycols such as polymethylene glycols. The surface of the metal may be cleaned by grit blasting, vapour degreasing, alkali cleaning or pickling, or a combination of these methods. A primer coat of, for example, rubber, plastics, epoxy resin, may be applied after the phosphate treatment and prior to the application of the polyester resin.
