METHOD FOR PRODUCING BLACK-PLATED STEEL SHEET, AND METHOD FOR PRODUCING MOLDED ARTICLE OF BLACK-PLATED STEEL SHEET |
摘要 |
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 0.1-22.0 mass%, inclusive, and containing Mg in the amount of 0.1-1.5 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. |
