Abstract
Ferrous strip is phosphated by treatment with an aqueous acidic zinc phosphate solution containing, by weight 0.05-1.5% zinc 0.12-7.5% calcium, 0.4-2.5% phosphate (as PO4), and an oxidizing agent other than chlorate in an amount sufficient to produce a uniform coating weighing at least 50 mg/sq. foot in not more than 10 seconds, and is then cold rolled. The process is applied to pickled hot-rolled strip. Suitable oxidizing agents are nitrates, nitrites, sulphites, hypochlorites, iodates, periodates, bromates, hydrogen peroxide, t-butyl hydroperoxide, quinones, and organic nitro-compounds such as picric acid, nitroguanidine, nitromethane, nitrourethane, nitraniline, nitrophenol, m - nitrobenzene sulphonate and dinitrobenzene sulphonate. The coatings may be rinsed with a dilute aqueous solution of chromic acid, borax, sodium nitrite or soda ash. The strip is preferably activated after pickling and prior to coating by treating it with an aqueous solution of oxalic acid; tetrasodium pyrophosphate; a mixture of tetrasodium pyrophosphate and a metaphosphate; a dialkyl metal phosphate containing lead, tin or arsenic; or tetrasodium pyrophosphate and/or disodium phosphate containing titanium or zirconium: suitable titanium compounds are the chloride, hydroxide, nitride and titanium potassium oxalate.
