新型高温超导复合材料的制备及其电磁、摩擦学性能研究

The synthesis and electromagnetic and tribological properties of novel high Tc superconductor composite

采用热压技术制备出YBCO/CU高温超导复合材料,复合材料中超导相的结构未受破坏,并且由于Cu的存在改善了材料的机械性能,因此相对于常规材料,该复合材料具有特殊的低温电磁学性能,并在低温下表现出与超导状态密切相关的摩擦学性能。

High Tc superconductor composite materials were synthesized by heat pressing technique.The struc-ture of superconducting phase was kept.The mechanical properties were improved due to the existence of Cu. So the composite material has special electromagnetic and tribological properties and at low temperature.The tight relation was revealed between tribological properties and superconducting state at low temperature.
