Title:
SURFACE-TREATED STEEL SHEET MANUFACTURING METHOD
Document Type and Number:
WIPO Patent Application WO/2014/132735
Kind Code:
A1
Abstract:
Provided is a manufacturing method of a surface-treated steel sheet provided with a metal oxide-containing film, characterized by involving a step for immersing a steel sheet for 0.1-10 seconds in a treatment liquid which contains at least fluoride ions and has a pH of 2-5, and a step for electrolytically treating the steel plate in the treatment liquid by creating a direct current between the steel sheet and an electrode to form a metal oxide-containing film on the surface of the steel sheet. By this means, it is possible to provide a surface-treated steel sheet manufacturing method which, when an organic resin layer is formed on the metal oxide film, can improve adhesiveness to the organic resin layer.
