Title:
PLATED MEMBER AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2024/075513
Kind Code:
A1
Abstract:
The present invention provides a nickel-plated aluminum member (plated member) which has improved uniformity and adhesion of plating and can be produced through a pretreatment for plating performed by a dry process. The present invention provides a plated member which is obtained by forming a nickel plating film on an aluminum base material that is formed of aluminum or an aluminum alloy, and which comprises, on the surface of the aluminum base material, an aluminum member that sequentially comprises, in the following order, a hydrophilic primer layer comprising at least one film that is selected from the group consisting of an oxide hydrate film containing aluminum oxide hydrate and an oxide film containing aluminum oxide, and a catalyst layer containing a plating catalyst that is composed of a metal or a metal oxide, and the nickel plating film that is formed on the catalyst layer of the aluminum member. The aluminum base material, on the surface of which the hydrophilic primer layer is formed, has a surface roughness Rz of 3 µm to 15 µm.
