摘要

本文设计了一种缓铅铋共晶（LBE）腐蚀的ta基耐高温高熵合金涂层（RHEA）。采用磁控溅射法制备涂层，在550℃和650℃下静置LBE 1000 h，通过SEM、GIXRD、TEM和划痕测试对涂层性能进行分析。沉积后的涂层呈双层结构，上层为BCC相，下层为非晶结构。经LBE腐蚀后，表面形成氧化层（主要为Fe-oxide）。涂层保持了良好的结构稳定性，没有明显的元素消耗，涂层内部氧化水平低。此外，由于元素在涂层和基体之间的相互扩散，涂层的结合强度大大增强。这些特性表明，与FeCrAlW、TiNbZrMoV、CrNbZrMoV、TiCrZrMoV、TiNbZrMoCr、AlCrFeMoTi和AlTiCrFe涂层相比，该涂层具有较好的耐腐蚀性。然而，涂层未能阻止铁的向外扩散。这是目前涂层的缺点，源于氧化层的阻隔作用不足。解决了这一问题后，可以考虑将其应用于核电系统。研究表明，结构稳定性、抗氧化性能和良好的附着力是镀层耐腐蚀的关键因素。对于HEA涂层而言，提高氧化层质量可能是今后提高其耐蚀性的关键措施之一。

Corrosion resistance of Ta-based TaCrWNbTi refractory high–entropy alloy coating in static lead–bismuth eutectic at 550 and 650℃ after 1000h

Herein, a Ta-based TaCrWNbTi refractory high-entropy alloy coating (RHEA) coating was designed for retarding lead-bismuth eutectic (LBE) corrosion. The coating was fabricated by magnetron sputtering technology and then exposed to static LBE at 550℃ and 650℃ for 1000 h. The performance was analyzed by SEM, GIXRD, TEM, and scratch test. The as-deposited coating exhibited a double-layer structure with upper BCC phase and lower amorphous structure. After LBE corrosion, an oxide layer (mainly Fe-oxide) was formed at the surface. The coating maintained good structural stability without apparent element consumption, and the interior of the coating had a low oxidization level. Additionally, the bonding strength of the coating was substantially enhanced due to the interdiffusion of elements between the coating and the substrate. These characteristics indicate that the coating possessed good corrosion resistance compared to FeCrAlW, TiNbZrMoV, CrNbZrMoV, TiCrZrMoV, TiNbZrMoCr, AlCrFeMoTi and AlTiCrFe coatings. However, the coating failed to prevent the outward diffusion of Fe. This is the current drawback of the coating, which stems from the insufficient barrier effect of the oxide layer. After solving this problem, it can be considered to be applied to nuclear power systems. This study indicates that structural stability, antioxidant properties and good adhesion are the key factors for corrosion-resistant coatings. For the HEA coating, improving the quality of the formed oxide layer may be one of the most critical measures for enhancing its corrosion resistance in the future.
