摘要

摘要: 采用等离子喷涂(Atmospheric plasma spraying , APS)法在炭/炭复合材料碳化硅（SiC）内涂层表面制备了硅酸钇涂层。分别采用XRD和SEM分析了所得涂层的微观结构，并测试了带有SiC/硅酸钇复合涂层的炭/炭复合材料试样在1500℃静态空气中的抗氧化性能。结果表明：通过调节喷涂粉料中的SiO₂和Y₂O₃的摩尔比，可制得Y₂SiO₅、Y₂Si₂O₇、Y₂Si₂O₇/Y₂SiO₅和Y₄Si₃O₁₂/Y₂Si₂O₇/ Y₂SiO₅四种不同结构的硅酸钇涂层；1500℃氧化73h后，SiC/Y₄Si₃O₁₂/Y₂Si₂O₇/Y₂SiO₅涂层试样的氧化失重速率相对较低，仅为1.01×10^-4 g · cm^-2 · h^-1。

Abstract: Different yttrium silicate coatings for SiC-coated C/C composites were designed and prepared by an atmospheric plasma spray method to prevent the C/C composites from oxidation. XRD profiles showed that the coating was composed of Y₂SiO₅, Y₂Si₂O7, and Y₄Si₃O₁₂. SEM showed that the gradient SiC/Y₄Si₃O₁₂/Y₂Si₂O₇/Y₂SiO₅coating had a more compact surface than the other coatings did. Isothermal oxidation tests at 1500℃ in air showed that the weight loss curves of the as-prepared C/C composites showed a linear tendency with time and the weight loss rate of all coated samples increased significantly after 73h. The coating could protect the C/C composites from oxidation at 1500℃ for 73h in air with a weight loss rate of 1.01×10^-4g · cm^-2 · h^-1. The SiC/Y₄Si₃O₁₂/Y₂Si₂O₇/Y₂SiO₅ was the better coating at high temperature than other coatings.
