Title:
NICKEL PLATING COATING AND PRODUCTION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2017/145492
Kind Code:
A1
Abstract:
[Problem] To apply a variety of potential difference patterns in Ni plating coatings more easily than in the prior art and provide a highly corrosion-resistant Ni plating coating. [Solution] In this method for producing a Ni plating coating comprising at least one Ni plating layer, the strength of agitation in a plating bath is changed during electroplating of a Ni plating layer in order to cause a variation in the potential of the resulting Ni plating layer in the depth direction of plating. A Ni plating coating comprising a D-Ni plating layer and a B-Ni plating layer in contact therewith has, in the D-Ni plating layer or the B-Ni plating layer, an intra-layer voltage variation region in which the potential varies at an average variation rate of 1 mV/0.1 µm in the depth direction of plating besides an interface voltage variation region at the interface between the D-Ni plating layer and the B-Ni plating layer.
