为了在液体冷却包层系统中获得氚渗透阻挡层和磁流体绝缘体，对金属有机分解（MOD）法制备的陶瓷涂层进行了性能测试和工艺改进。在本研究中，MOD Er 2 O3涂层的低活化铁素体钢基板上的制造已被测试在减压条件下。测得的氢渗透减少因子>100表明在减压下制造MOD涂层对于抑制基底的氧化和实现上级涂层性能是有效的。虽然MOD涂层的堆叠度明显低于烧结体材料，但电导率和击穿电压测量结果表明MOD Er 2 O3涂层将具有足够的性能作为Li/V合金毯系统中的MHD绝缘涂层。利用扫描电子显微镜（SEM）的阴极发光测量成功地应用于MOD涂层的微观表征。
Performance tests and process improvement for ceramic coatings fabricated by the metal organic decomposition (MOD) method have been conducted to obtain tritium permeation barrier and MHD insulator in liquid cooled blanket systems. In the present study, fabrication of MOD Er2O3coating on a low activation ferritic steel substrate has been tested under reduced pressure condition. Measured hydrogen permeation reduction factors of >100 indicate that MOD coating fabrication under reduced pressure would be effective for suppression oxidation of a substrate and achieving superior coating performances. While crystallinities of MOD coating layers are significantly lower compared with sintered bulk materials, results of electrical conductivity and breakdown voltage measurements indicate that MOD Er2O3coatings would have sufficient performances as an MHD insulation coating in a Li/V-alloy blanket system. Cathodoluminescence measurement using scanning electron microscope (SEM) is successfully applied to microscopic characterization of MOD coating layers.
