摘要

摘要在这项研究工作中，我们在 1173-1323 K 的温度范围内对 Sleipner 钢进行了 1 到 10 小时的包硼处理。我们的研究包括通过相间形态检查和扫描电子显微镜测量层厚度来评估钢的微观结构。为了确定硼化层的相组成，我们采用了 X 射线衍射分析法。此外，我们还利用 EDS 图谱和 EDS 点分析法研究了硼化过程中某些元素的重新分布情况。结果发现，硼化物层由 FeB 和 Fe2B 相组成。我们使用维氏方法对扩散区、Fe2B 和 FeB 进行了显微硬度测试。最后，我们利用扩散模型评估了硼在 FeB 和 Fe2B 中的活化能，并以活化能的形式展示了结果。

Pack-boriding of Sleipner steel: microstructure analysis and kinetics modeling

Abstract In this research work, we subjected the Sleipner steel to pack-boronizing within the temperature range of 1173–1323 K, lasting from 1 to 10 h. Our study involved assessing the steel’s microstructure by examining interphase morphology and measuring the layers’ thicknesses through scanning electron microscopy. To determine the phase composition of the boronized layers, we employed X-ray diffraction analysis. Furthermore, we investigated the redistribution of certain elements during the boronizing process using EDS mapping and EDS point analysis. The boride layers were found to consist of FeB and Fe2B phases. We conducted microhardness testing using the Vickers method on the diffusion zone, Fe2B, and FeB. Lastly, we utilized a diffusion model to evaluate the activation energies of boron in FeB and Fe2B, and we presented the results in terms of activation energies.
