摘要
Preparation of the metal surface of an object, notably a steel sheet, for subsequent direct enamelling, comprises: (a) a preliminary pickling or degreasing operation; (b) amorphous phosphating to form a layer of at least 0.2 g/m2 on the metal surface; and (c) nickel-plating. In a complete sequence for the fabrication of an object formed from an enamelled steel sheet it is possible to form the object after the pickling stage, notable after the phosphating stage and before the final nickel-plating stage.
