Document Type and Number:
WIPO Patent Application WO/2014/192082
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a supplement that avoids an increase in the HF concentration in a surface-treatment liquid for metal materials, is capable of supplying zirconium ions at high concentration by using the metal material surface-treatment liquid, and has excellent long-term storage stability, in order to continuously chemically convert and/or electrolytically treat a metal material. This supplement contains prescribed amounts of: a zirconium compound (A) not containing fluorine and including at least one type selected from a group comprising zirconium basic carbonate, zirconium carbonate, zirconium hydroxide, and ammonium zirconium carbonate; a fluorine-containing matter (B) including at least one type selected from a group comprising hydrofluoric acid, a hydrofluoric acid salt, fluorozirconic acid, and a fluorozirconic acid salt; and an acid component (C) including at least one type selected from a group comprising nitric acid, hydrochloric acid, sulfuric acid, and acetic acid.
