The structure and phase transformation of the coating during spraying and after-annealing treatment process were studied by X-ray diffraction, TEM, SEM and DTA technique.The results show that the as-sprayed coating lost its superconductivity completely at liquid nitro-gen temperature and was composed mainly of microcrystalline and amorphous structure. Its su-perconductivity can be restored by a proper annealing at 850--950℃. Key words:  superconductivity      plasma spraying      microstructure      coating      Received:  18 March 1988      Service E-mail this article Add to citation manager E-mail Alert RSS （） Articles by authors URL:  https://www.ams.org.cn/EN/     OR     https://www.ams.org.cn/EN/Y1988/V24/I3/286 1 Wu M K, Ashburn J R, Torong C J, Hor P H, Meng R L, Gao L.
