Abstract: An aqueous bath for imparting a brown surface coating to brass workpieces is provided by an aqueous solution of cupric carbonate; a thiosulfate or hydrosulfite color modifier; an organic color intensifier; and ammonium hydroxide in an amount sufficient to provide a pH of about 10.5 to 12.5. The workpieces are immersed in the bath, preferably at ambient temperature, for a period of time sufficient to develop a uniform brown finish thereon. The color intensifiers may be aliphatic and aromatic carboxylic acids, aliphatic and aromatic aldehydes, aliphatic and aromatic ketones, aliphatic and aromatic amines, aliphatic alcohols, oxidation-resistant hydroxybenzene compounds, aromatic phosphonic and sulfonic acids, and mixtures thereof.

Abstract: A substrate having high absorptance and emittance is produced by roughening the surface of the substrate, immersing the substrate in a first electroless plating bath having a low phosphorus to nickel concentration, then immersing the substrate in a second electroless plating bath having a phosphorus to nickel concentration higher than that of said first electroless plating bath. Thereafter, the resulting electroless nickel-phosphorus alloy coated substrate is immersed in an aqueous acidic etchant bath containing sulfuric acid, nitric acid and divalent nickel to develop a highly blackened surface on said substrate.

Abstract: The invention allows one to obtain a strongly adherent dark grey to black coating, with good corrosion resistance, on aluminium and its alloys. The degreased aluminum is pre-treated in an aqueous solution containing at least one salt of a metal which is less electronegative than aluminium. It is then colored in another aqueous solution containing molybdate ions and at least one fluorine compound and/or a heavy metal chloride, and/or an organic chlorine compound with active chlorine atoms.

Abstract: A method of controlling the iron content of a zinc phosphating process. The processing bath is continuously aerated and agitated to precipitate iron compounds out of solution and maintain the precipitate in suspension. The bath is constantly recirculated through a series of settling tanks or a single compartmentalized tank wherein the precipitate is settled out of solution and from which relatively clarified solution is discharged back to the processing bath. Periodically iron bearing sediment is removed from the settling tanks for disposal as solid waste.

Abstract: Colored coatings are produced by first subjecting an aluminum or its alloys to anodic oxidation in an electrolyte containing mainly sulfuric acid, by supplying an electric current comprising a direct current component and an alternating current component with the alternating current component at least as large as the direct current component, dipping the oxide coating in an aqueous solution containing metallic cations or anions without supplying the electric current and then subjecting the coating to sealing treatment to produce coloring thereof.

Abstract: This invention relates to a method for coloring stainless steel by controlling the potential difference between the surface of the stainless steel being colored and a reference electrode in a coloring liquor, characterized by differentiating a potential-time curve showing the variation with time of the potential difference between the surface of the stainless steel and the reference electrode by time to prepare the differentiation curve thereof and removing the stainless steel from the coloring liquor when the potential difference has changed from the coloring starting point that is the inflexion point on this differentiation curve, at which the variation amount of the potential per unit time changes from a falling tendency to a rising tendency, by a predetermined amount associated with the desired color.
