Title:
APPARATUS AND METHOD FOR FORMING METAL COATING FILM
Document Type and Number:
WIPO Patent Application WO/2014/156310
Kind Code:
A8
Abstract:
Provided are an apparatus and a method for forming a metal coating film, whereby it becomes possible to form a metal coating film having a desired film thickness on the surfaces of multiple bases continuously and it also becomes possible to increase the film formation speed while preventing the occurrence of defects in the metal coating film. A film formation apparatus (1A) is equipped with at least: an anode (11); a solid electrolytic film (13) which is arranged between the anode and a base (B) that serves as a cathode and in which a metal ion solution (L) is arranged on the anode (11) side; and an electric power supply section (E) which can apply a voltage between the anode (11) and the base (B). A voltage is applied between the anode (11) and the base (B) to cause the deposition of a metal from metal ions, which are contained in the inside of the solid electrolytic film (13), on the surface of the base (B), thereby forming a metal coating film (F) comprising the metal of the metal ions. The anode (11) comprises: a base material (11a) which is insoluble in the metal ion solution (L); and a metal plating film (11c) which is composed of the same metal as that constituting the metal coating film (F) and is coated on the base material (11a).
