スポンサーリンク
概要
- 論文の詳細を見る
Thick films composed of Y-Ba-Cu-O (e.g. 70 μm thick) were prepared on Ni alloy substrates at various temperatures by the atmospheric plasma powder spraying method. By increasing the substrate temperature during the spraying, the amount of unknown structure in the film sprayed was lowered and the structure of the film sprayed on 600℃ substrate was tetragonal in phase. After the postannealing at 600℃, this film revealed superconducting temperatures for onset and zero resistance of 92 K and 86 K,respectively.
