Abstract: The present invention pertains to a method for producing a black-plated steel sheet capable of being blackened in a short amount of time, and exhibiting an excellent ability to maintain a black appearance after processing. As an original sheet, the sheet used is a Zn-plating steel sheet which contains molten Al and Mg and has a Zn-plating layer containing molten Al and Mg, containing Al in the amount of 1.0-22.0 mass %, inclusive, and containing Mg in the amount of 1.5-10.0 mass %, inclusive. The plating layer is blackened by causing the molten-plating steel sheet to contact water vapor inside a tightly sealed container. When doing so, the concentration of oxygen inside the tightly sealed container is 13% or less.

Abstract: A process for passivation of strip steel plate, having the following steps: electrochemical treatment of the black plate by passing the black plate through an electrolyte to form an inert steel surface; rinsing the black plate; and application of an aqueous chromium-free treatment solution to at least one surface of the black plate to form a conversion layer that protects against corrosion and an adhesion layer for paints and organic coating materials. The black plate treated in accordance with this process is characterized by high corrosion resistance and has good bonding capacity for paints and organic coatings and therefore is very suitable as a substitute for tin-free steel (TFS or ECCS) and tinplate for the production of packagings, in particular cans. In contrast to the traditional manufacturing and passivation processes for tin-free steel and tinplate, no chromium VI, which is environmentally hazardous and hazardous to health, is used in this process.

Abstract: Aqueous compositions useful as pretreatments prior to painting and to prevent the formation of white rust in the uncoated condition include an organopolyphosphonic acid or salt thereof, an organosilane, and a trivalent chromium compound. A method for treating a surface of a zinc-containing metal includes contacting the surface with an aqueous composition including an organopolyphosphonic acid or salt thereof, an organosilane, and a trivalent chromium compound. The composition may also include an agent for reducing hydrophilicity, such as a polyacrylic acid. The aqueous composition has been found to be particularly well-suited for treating a zinc-containing metal to passivate the surface, improve paint adhesion, and/or improve corrosion resistance.
