Protective aluminum-based coatings represent a promising anti-permeation and anti-corrosion barrier for breeding blanket systems developed for European DEMO fusion reactor. Following the prior in-depth characterizations, selected coating candidates were subjected to a combined test consisting of contact with liquid Pb-16Li, its repeated in-situ solidification and re-melting, tritium permeation during gamma and neutron irradiation in the LVR-15 fission reactor. During the sample exposure in the reactor, the temperature of Pb-16Li was between 300 and 425 °C. The irradiation damage averaged over the sample volume estimated by FISPACT code was limited to 0.037 dpa. This article presents post-irradiation characterization of cylindrical Eurofer97 samples coated by electro-chemical X-metal deposition from ionic liquid (ECX) and pulsed laser deposition (PLD) techniques. The coating damage relative to a reference uncoated sample is discussed.

铝基保护涂层代表了为欧洲DEMO聚变反应堆开发的育种毯系统的有希望的防渗透和防腐蚀屏障。根据先前的深入表征，对选定的涂层候选物进行组合测试，包括与液态Pb-16Li接触，其反复原位固化和重熔，在LVR-15裂变中的γ辐射和中子辐照期间的ium渗透反应堆。在反应器中暴露样品期间，Pb-16Li的温度在300至425°C之间。通过FISPACT代码估算的样品体积的平均辐射损伤被限制在0.037 dpa。本文介绍了通过离子液体的电化学X-金属沉积（ECX）和脉冲激光沉积（PLD）技术涂覆的圆柱形Eurofer97样品的辐照后表征。讨论了相对于参考未涂层样品的涂层损伤。
