Title:
ELECTROPLATING BATH, METHOD FOR FORMING ELECTROPLATING COATING, AND ELECTROPLATED PRODUCT
Document Type and Number:
WIPO Patent Application WO/2012/053283
Kind Code:
A1
Abstract:
The present invention provides an electroplating bath with which an electroplating Fe-W alloy coating may be formed. The elemental composition of the electroplating coating (energy dispersive X-ray spectroscopy, same hereafter) is W: 2 to 70%, Mn: 0.05 to 1.0%, S: 0.1 to 8%, and Fe: the remainder. The electroplating coating contains a water soluble S-containing compound along with 1) water soluble Fe (II, III) salt, 2) water soluble W (VI) acid salt, and 3) water soluble Mn (II) salt. An electroplating coating (15) is formed on a base material (11) on which an underlayer plating (13) has been applied, after which heating treatment (post processing) is performed at a temperature of 200 to 1000°C to form an electroplating coating (15A).
