Abstract High-throughput methods were developed to prepare multicomponent Nb Si based (NbxCryTizSi1-x-y-zAl0.5) alloy film combinatorial libraries (x = 0 → 0.95, y = 0 → [0.95-x], z = 0 → [0.95-x-y]) with composition gradients. Oxidation behavior of the as-deposited film was investigated in dry air at 1250 °C. The results show that the as-deposited film is consisted of a mixture of amorphous and crystalline phases. Crystallized film is composed Cr2Nb, Nb5Si3 and Nbss phases after annealing. The film after oxidation at 1250 °C for different times exhibits three regions of distinct oxidation behavior. The composition for establishment of a protective CrNbO4 scale across the entire film is determined rapidly.

成分梯度 Nb-Si 基合金薄膜的显微组织和抗氧化性

摘要 开发了高通量方法来制备多组分 Nb Si 基 (NbxCryTizSi1-xy-zAl0.5) 合金膜组合库 (x = 0 → 0.95, y = 0 → [0.95-x], z = 0 → [0.95- xy]) 具有成分梯度。在 1250 °C 的干燥空气中研究沉积膜的氧化行为。结果表明，沉积的薄膜由非晶相和结晶相的混合物组成。结晶膜在退火后由 Cr2Nb、Nb5Si3 和 Nbss 相组成。在 1250 °C 氧化不同时间后的薄膜表现出三个不同的氧化行为区域。快速确定用于在整个薄膜上建立保护性 CrNbO4 水垢的成分。
