| description | A metal surface comprising iron is contacted with an aqueous phosphating solution comprising nickel ions and having a pH in the range 4.0 to 5.5, to form a coating comprising iron phosphate and nickel phosphate. An enamel frit is subsequently applied to the coated surface and is fired. The phosphating solution may contain an accelerator such as a fluoride in an amount up to 0.5 g/l and the nickel ions are preferably present in an amount 0.1-2.0 g/l and the phosphate ions in an amount 1-12 g/l. The enamel may be concentrated and is applied by conventional methods. A particular solid composition for use in forming the phosphating solution when dissolved in water comprises a mixture of an alkali metal or ammonium dihydrogen phosphate and a water-soluble inorganic nickel salt and optionally an alkali, a surfactant and/or an accelerator. |
