SUPERCONDUCTING JOINT METHOD OF SUPERCONDUCTING WIRE

摘要

The present invention relates to a superconducting joint method which can prevent a defect of a superconducting joint and enhance mechanical strength. For this, the superconducting joint method comprises: a step of removing a protective layer located at a joint of the superconducting wire so as to expose a superconducting layer; a step of arranging the joint which has gone through the step of removing the protective layer; a superconducting powder layer formation step of forming a superconducting powder layer on the superconducting layer of the joint which has gone through the step of arranging the joint; a first heat processing step of heat-treating the joint which has gone through the step of forming the superconducting powder layer by adding pressure; a protective cover layer formation step of forming a protective cover layer on the superconducting powder layer of the joint which has gone through the first heat processing step; and a second heat processing step of pressurizing the joint which has gone through the protective cover layer formation step so as to be connected at a high temperature oxygen atmosphere.
