In engineering applications, superconducting tapes are continually challenged by higher magnetic fields and higher engineering currents, with the attendant demands on superconducting tapes with ever higher mechanical properties.
The second generation high temperature superconducting strip is a layered structure, generally a buffer layer, a superconducting layer and a silver plating layer are sequentially prepared on hastelloy, and copper plating and armoring are carried out as required, but due to the multi-layered structure, in each preparation process, due to the fact that process parameters are unstably controlled, lattice arrangement does not reach standards, the film thickness is too thick or defects caused by previous processes are easily caused, the situation that the binding force is not firm is easy to occur, and once a finished product is manufactured, whether the binding force is good or not is difficult to judge from the microstructure. The products with risk points can be subjected to complicated mechanical external force in the engineering application process, and because the second-generation high-temperature superconducting tapes are of a laminated structure, the force which can be endured and is vertical to the tape surface is weakest.
