采用低压等离子体喷涂-物理气相沉积法在NiCoCrAlY金属载体上成功制备了致密的La0.6Sr0.4Fe0.8Co0.2O3−δ（LSFC）膜。氦泄漏率测试和扫描电镜微观结构分析表明，膜层的气密性。膜厚度在40和65μm之间。氧渗透通量在大气压力下在空气-Ar梯度中在700 ° C和950°C之间的不同温度下测定，并与1 mm厚的LSFC粒料进行比较。虽然检测到泄漏，但报道了支撑膜的显著氧渗透速率（在885°C下为0.3mlcm-2 min-1）。
Dense La0.6Sr0.4Fe0.8Co0.2O3−δ(LSFC) membranes were successfully prepared on NiCoCrAlY metal supports by low pressure plasma spraying-physical vapour deposition. He leakage rate tests and microstructural analysis by SEM of the as-deposited films showed that a gas-tight membrane layer is achieved. Membrane thicknesses are between 40 and 65µm. The oxygen permeation flux was determined at atmospheric pressure in an air-Ar gradient at different temperatures between 700 and 950°C and compared with 1mm thick LSFC pellet. Although leakage was detected, noteworthy oxygen permeation rate of the supported membranes (∼0.3mlcm−2min−1at 885°C) is reported.
