摘要

研究了质子同步辐照和铅铋共晶腐蚀对非晶feraltimo涂层的协同作用。结果表明,质子辐照对涂层的抗LBE腐蚀性能有积极的影响。实验和模拟结果表明,在600℃下,辐照诱导的自由体积湮灭降低了扩散动力学,导致腐蚀速率减慢,这挑战了辐照损伤对材料腐蚀产生负面影响的传统观点。最后,提出了一种新的辐照减速腐蚀机理,为设计耐腐蚀、耐辐照的核结构材料提供了新的思路。

Decelerated lead-bismuth eutectic corrosion of FeCrAlTiMo coating by in situ proton irradiation
Synergistic effect of the simultaneous proton irradiation and lead-bismuth eutectic (LBE) corrosion on the amorphous FeCrAlTiMo coatings was investigated. Results displayed that proton irradiation had a positive effect on LBE corrosion resistance of the coating. The experimental and simulation results demonstrated that irradiation-induced annihilation of the free volume reduced the diffusion kinetic and lead to slower corrosion rate at 600 °C, which challenged the traditional wisdom that irradiation damage resulted in negative effect on materials corrosion. Finally, a novel mechanism of irradiation-decelerated corrosion was proposed, which provided a new approach for designing nuclear-structural materials with better corrosion and irradiation resistance.

期刊介绍: This journal is a platform for publishing innovative research and overviews for advancing our understanding of the structure, property, and functionality of complex metallic alloys, including intermetallics, metallic glasses, and high entropy alloys. The journal reports the science and engineering of metallic materials in the following aspects: Theories and experiments which address the relationship between property and structure in all length scales. Physical modeling and numerical simulations which provide a comprehensive understanding of experimental observations. Stimulated methodologies to characterize the structure and chemistry of materials that correlate the properties. Technological applications resulting from the understanding of property-structure relationship in materials. Novel and cutting-edge results warranting rapid communication. The journal also publishes special issues on selected topics and overviews by invitation only.
