Patent ID: 10753008

Abstract:
In a method of manufacturing a Ni plated coating that includes at least one Ni plated layer, an agitation intensity of a plating bath is changed while the Ni plated layer is being electrodeposited to change potential of the deposited Ni plated layer in a deposition depth direction. A Ni plated coating including a D-Ni plated layer and a B-Ni plated layer adjoining the D-Ni plated layer has, other than an interface voltage changing region at an interface between the D-Ni plated layer and the B-Ni plated layer, an in-layer voltage changing region in which, in the D-Ni plated layer or in the B-Ni plated layer, potential is changed in a deposition depth direction at an average rate of 1 mV/0.1 μm or greater.
