摘要

针对zrb2基涂层在氧化过程中因结构松动导致的保护失效问题,提出了一种双硅化物协同增强的一步粉末源原位合金化策略。该方法成功制备了具有精确可控成分的ZrB2-ZrSi2-MoSi2复合粉末,并将其用于在石墨基体上构建高性能抗氧化涂层。与未掺MoSi2的涂层相比,掺MoSi2含量为40 vol%的ZZM40涂层在1973 K下的氧渗透率降低了98.21 %,碳损失率降低了84.03 %,保护效率达到99.58 %。性能的增强归因于氧化过程中原位形成的自生成玻璃相,其具有高流动性和自修复特性。此外,原位沉淀的纳米级MoB相通过钉住效应有效地抑制了B2O3的挥发,从而协同增强了热稳定性和阻氧能力。值得注意的是,过量的MoSi2掺杂50 vol%会导致有害的影响。MoO3挥发加剧,降低了玻璃相的粘度,引发了缺陷扩展的链式反应,与ZZM40相比,碳损失率提高了34.43 %。提出的粉末源原位合金化策略验证了双硅化阻氧增强驱动的缺陷修复机制,为下一代高温热防护材料的设计和应用提供了重要的理论基础。

In-situ engineered ZrB2-ZrSi2-MoSi2 coatings with self-healing multiphase glass networks for superior oxidation protection at 1973 K
To address the protection failure of ZrB2-based coatings caused by structural loosening during oxidation, an in-situ alloying strategy with dual-silicide synergistic enhancement via one-step powder-source alloying is presented in this study. The approach successfully produced ZrB2-ZrSi2-MoSi2 composite powders with precisely controllable composition, which were subsequently used to construct high-performance oxidation resistant coatings on graphite substrates. The optimized ZZM40 coating with 40 vol% MoSi2 demonstrated a remarkable 98.21 % reduction in oxygen permeability and an 84.03 % reduction in carbon loss rate at 1973 K compared to the undoped coating, achieving a protection efficiency of 99.58 %. The performance enhancement is attributed to the in-situ formation of a self-generated glass phase during oxidation, which exhibits high fluidity and self-healing properties. Additionally, the in-situ precipitated nanoscale MoB phase effectively suppresses the volatilization of B2O3 through a pinning effect, achieving a synergistic enhancement in thermal stability and oxygen blocking capabilities. Notably, excessive MoSi2 doping at 50 vol% leads to detrimental effects. Intensified MoO3 volatilization reduces the viscosity of the glass phase and triggers a chain reaction of defect propagation, consequently increasing the carbon loss rate by 34.43 % compared to ZZM40. The proposed powder-source in-situ alloying strategy validates the defect-repair mechanism driven by dual-silicide oxygen-blocking reinforcement, providing crucial theoretical foundations for the design and application of next-generation high-temperature thermal protection materials.
