【Abstract】 A high-Tc YBaCuO superconducting coating, which is well bonded, homogeneous, technologically repeatable and stable, with zero-resistance temperature of 84K, has been produced by means of the plasma spray technique. The microstruc- ture and phase transformation of the coating were studied using X-ray diffraction, electron microprobe and differential thermal analysis techniques. The influence of plasma spray and post-spray treatment process parameters on the superconducting properties of the coating is approached.更多还原
