Y-Ba-Cu系氧化物在液氮温区的高温超导电性被发现以来,其潜在应用价值引起了人们的极大兴趣。由于陶瓷材料所特有的高脆性使其加工性能极差,有效的成材途径成为这种氧化物超导陶瓷的实用化进程中主要研究方向之一。我们曾报道了用等离子喷涂工艺制备成YBa_2Cu_3O_(7-x)超导涂层的结果,运用此方法可以方便、灵活、有效地在多种基材上复合超导材料,得到超导电气元件。Neiser等及Cuomo等的结果也证实了
Since the high-temperature superconductivity of Y-Ba-Cu oxide has been found in the liquid nitrogen temperature region, its potential application has aroused great interest. Due to the high brittleness of the ceramic material, its processing performance is extremely poor. An effective way of forming the material becomes one of the main research directions in the practical application of the oxide superconducting ceramic. We have reported the results of plasma sprayed YBa2Cu_3O_ (7-x) superconducting coatings prepared by this method. This method can be easily and flexibly and effectively composite superconducting materials on various substrates to obtain superconducting electrical components. The results of Neiser et al. And Cuomo et al. Also confirmed
