Abstract

In the presented work, 321 Stainless Steel + B₄C + Al₂O₃ compounds were synthesized by atmospheric plasma technique, with 167 MeV energy swift heavy Xe²⁶⁺ ions were irradiated with different flux and structure, defect formation and Raman spectroscopic analyzes were performed. The total number of displacements was determined based on the DPA and NRT model of interacting ions with SRIM/TRIM calculations. Depending on the concentration of B₄C crystal, phase space groups, lattice parameters, surface morphology and their changes were determined in non-irradiated and SHI-irradiated compounds by structural analysis. Raman shift analyzes were performed depending on the change of Al₂O₃ concentration on the surface of the compound after SHI irradiation. It has been established that SHI radiation causes the formation of defect centers on the surface and volume of the 321 Stainless Steel + B₄C + Al₂O₃ compound, amorphization of the surface, and reduction of the lattice parameters in the existing structural phases.

快速重离子辐照下 321 不锈钢上 Al2O3-B4C 涂层的晶格参数变化、缺陷动力学和表面形貌表征

在本研究中，采用大气等离子体技术合成了 321 不锈钢 + B4C + Al2O3 复合物，用 167 MeV 能量的迅猛重 Xe26+ 离子以不同的通量进行辐照，并进行了结构、缺陷形成和拉曼光谱分析。根据离子相互作用的 DPA 和 NRT 模型以及 SRIM/TRIM 计算，确定了位移总数。根据 B4C 晶体的浓度，通过结构分析确定了未辐照和 SHI 辐照化合物的相空间群、晶格参数、表面形貌及其变化。根据 SHI 照射后化合物表面 Al2O3 浓度的变化，进行了拉曼偏移分析。结果表明，SHI 辐射会在 321 不锈钢 + B4C + Al2O3 复合物的表面和体积上形成缺陷中心，使表面非晶化，并降低现有结构相的晶格参数。
