Adopting chemical etching to strip the Stabilizers of YBCO superconducting tapes (Cu and Ag layer).Studying the effects of different ratio and temperature of etching solution (NH3.H2O and H2O2), corrosion time on the performance of tapes.Using the four probe method (liquid nitrogen environments) to test the critical current of tapes after stripping.The critical current of original tapes is 90 A, after chemical stripping is nearly 90 A.The surface and cross-sectional analysis of superconducting layer after stripping was researched by scanning electron microscopy.There is no difference was observed on microstructural between original and chemical stripping tapes, indicating that chemical etching stripping strip stabilizing layer is desirable.
