Problems solved by technology

If the surface of the superconducting strip is plated with sandy copper in the sand surface copper solution, the bone structure of the strip will affect the winding of the strip.

[0010] Patent document CN108342757B discloses a method for electroplating copper to prepare a high-temperature superconducting strip protective layer, which includes the following steps: step 1, preparing a copper protective layer on the high-temperature superconducting strip by using a copper electroplating process; step 2, preparing a copper protective layer on the back of the superconducting layer The baseband is electroplated with copper. This design alone still cannot solve the problem that the liquid contacts the strip through the holes on the silver-plated surface and affects the performance of the strip.
