We have proposed a method for effectively repairing locally defective or damaged HTS coated conductors produced during manufacturing HTS coated conductor or coil winding for magnet applications using superconducting patch. The superconducting patch was fabricated by separating the metal substrate from the commercial HTS coated conductor using the interface delamination phenomenon. And it has high Je(engineering critical current density) coated conductor with simple structure of "stabilizing layer / superconducting layer / stabilizing layer". This idea is that a reduced critical current can be recovered by attaching a superconducting patch to the defective or damaged coated conductor. In this presentation, a detailed introduction to the idea and experimental results to investigate its feasibility are discussed.
