Abstract
This study focused on the synthesis of Ti36-Al16-V16-Fe16-Cr16 high-entropy alloys (HEAs) through spark plasma sintering to ascertain their corrosion resistance performance. Varied sintering temperatures, ranging from 700 to 1100 °C were employed to discern their impact on the alloy's characteristics. The fabricated HEAs underwent characterization using scanning electron microscopy and X-ray diffraction. A potentiodynamic polarization measurement was employed to compare the electrochemical properties of HEAs sintered at different temperatures in sulfuric and chloride aggressive media. The study outcomes indicate that the HEA sintered at 1000 °C exhibited superior corrosion resistance compared to other HEAs at other temperatures. This study contributes valuable insights into the nuanced relationship between sintering temperature, microstructure, and corrosion resistance of Ti36-Al16-V16-Fe16-Cr16 HEAs.
本研究的重点是通过火花等离子烧结合成 Ti36-Al16-V16-Fe16-Cr16 高熵合金 (HEA)，以确定其耐腐蚀性能。烧结温度从 700 ℃ 到 1100 ℃ 不等，以确定其对合金特性的影响。利用扫描电子显微镜和 X 射线衍射法对制备的 HEA 进行了表征。电位极化测量用于比较在硫酸和氯化物侵蚀介质中不同温度下烧结的 HEA 的电化学特性。研究结果表明，与其他温度下的 HEA 相比，在 1000 °C 下烧结的 HEA 具有更优异的耐腐蚀性。这项研究有助于深入了解 Ti36-Al16-V16-Fe16-Cr16 HEA 的烧结温度、微观结构和耐腐蚀性之间的微妙关系。
