摘要：

An original method of superconductor preparation is described. It involves special surface preparations of the metal support, powder sedimentation, pressing and sintering. Typical 90 mum thick coatings with 20% Ag exhibit high adherence to the rough substrate, and the diffusion depth of metallic elements into the coating is less than 10 mum. Comparison is made with pure YBa2Cu3O7-x coatings: silver addition improves the electrical and mechanical properties. As shown by in situ high-temperature x-ray diffractometry, Ag accommodates mechanical stresses induced by temperature variation during preparation, more particularly on cooling.
