Abstract
Official abstract text for this publication.
[Object] To provide a roughened nickel-plated material in which the formation unevenness such as generation of the unevenness or grooves in a roughened nickel plated layer is restrained. [Solving Means] A roughened nickel-plated material including a base material that is a rolled material, and a roughened nickel plated layer formed on at least one surface of the base material, in which SRzjis of the surface of the roughened nickel plated layer is equal to or more than 2 μm, and, letting a maximum height of the roughened nickel plated layer be SRz, a valley region B in a given virtual planer region A as observed at a height position of SRz×0.25 satisfies the following (i). (i) The length of the valley region B in the rolling direction RD of the base material is less than 40 μm in a direct distance.
First claim
Opening claim text (preview).
The invention claimed is: 1. A roughened nickel-plated material a base material that is a metal; and a roughened nickel plated layer formed on at least one surface of the base material, wherein Str of three-dimensional surface property parameters of the surface of the roughened nickel plated layer is equal to or more than 0.1, and wherein brightness of color of the surface of the roughened nickel plated layer is 30 to 50 in L* value. 2. The roughened nickel-plated material according to claim 1 , wherein, further, Sk of the three-dimensional surface property parameters of the surface of the roughened nickel plated layer is 1.0 to 4.0 μm. 3. The roughened nickel-plated material according to claim 1 , wherein, further, Vvc of the three-dimensional surface property parameters of the surface of the roughened nickel plated layer is 0.6 to 3.0 μm 3 /μm 2 . 4. The roughened nickel-plated material according to claim 1 , wherein, further, Vmc of the three-dimensional surface property parameters of the surface of the roughened nickel plated layer is 0.45 to 2.0 μm 3 /μm 2 .
