    摘要: The invention concerns a method which consists in: providing a protective treatment against corrosion to the initial sheet metal using an aqueous emulsion containing colloids based on acrylic and/or methacrylic polymer; a step which consists in applying a coat of liquid enamelling composition comprising an enamel frit capable of being vitrified; a baking step adapted to vitrify said frit. The invention is characterised in that said method does not comprise a step for degreasing said surface subsequent to the protective treatment. The invention provides the advantages of improved adherence of the enamel and a simpler process.

    摘要: A process and product are disclosed relating to the preparation of a metallic substrate of a workpiece for a subsequent deposition of a ceramic coating, such as porcelain enamel, in which the metal of the substrate is one that is not sufficiently electrochemically active to be coated by electrophoresis, for example, stainless steel or those alloys containing principally nickel and/or chromium. In one form, the metallic substrate is first covered with an oxide, and preferably a thermally decomposable compound, of a transition metal selected from Groups IIIB through Group IIB of the Periodic Table of The Elements. The workpiece is then heated to alloy the transition metal with the substrate of the workpiece, after which a ceramic coat may be applied. When the transition metal is present as a thermally decomposable compound, the compound must decompose prior to reaching an alloying temperature.

    摘要: An improved surface on sheet steel having a carbon content below 0.01%, preferably below 0.003%, for subsequent porcelain enameling or the deposition of a metal or organic, e.g., paint, coating thereon or in preparation of the sheet steel for a subsequent laminating operation, is provided by subjecting the sheet steel having a carbon content below about 0.1% by weight to oxidation in the presence of air under conditions to build up on the surface of the sheet steel undergoing oxidation an oxide layer having a thickness in the range 0.1-1.5 mils and such that the oxidized sheet steel exhibits a gain in weight of at least about 0.5 grams per square foot of oxidized surface, followed by subjecting the resulting oxidized sheet steel to reduction in an atmosphere consisting essentially of nitrogen and hydrogen, preferably at a temperature isothermal with the aforesaid oxidation temperature, such as at a temperature in the range 1000*-1500*F., to reduce substantially all of the oxide layer to metal and then subjecting the resulting oxidized-reduced sheet steel to decarburization at a temperature in the range 1000*1500*F. in an atmosphere consisting essentially of nitrogen, hydrogen and water vapor.
