Abstract
Official abstract text for this publication.
An oxide superconducting wire includes a superconducting laminate including an oxide superconducting layer disposed, either directly or indirectly, on a substrate, and a stabilization layer which is a Cu plating layer covering an outer periphery of the superconducting laminate, and a Vickers hardness of the Cu plating layer is in the range of 80 to 190 HV.
First claim
Opening claim text (preview).
The invention claimed is: 1. An oxide superconducting wire comprising: a superconducting laminate comprising an oxide superconducting layer disposed, either directly or indirectly, on a substrate; and a stabilization layer which is a Cu plating layer covering an outer periphery of the superconducting laminate, wherein a Vickers hardness of the Cu plating layer is in a range of 70 to 195 HV, and an average number of grain boundaries per 100 μm length of the Cu plating layer is 80 or more. 2. An oxide superconducting wire comprising: a superconducting laminate comprising an oxide superconducting layer disposed, either directly or indirectly, on a substrate; and a stabilization layer which is a Cu plating layer covering an outer periphery of the superconducting laminate, wherein a Vickers hardness of the Cu plating layer is in a range of 70 to 195 HV, an average crystal grain size of the Cu plating layer is in a range of 0.52 to 1.25 μm, and an average number of grain boundaries per 100 μm length of the Cu plating layer is 80 or more.
