摘要

通过电子束包覆 Al7(CoFeNi)86Ti7 HEA 粉末,在 Ti-6Al-4 V 上形成了高熵合金 (HEA) 涂层。通过正交实验分析确定的最佳电子束熔覆参数为加速电压为 64 kV,焊接束电流为 12 mA,扫描时间为 3 s。研究了使用最佳参数制备的涂层的微观结构、相组成、纳米硬度和耐磨性。涂层顶部、中部和底部区域的主相分别为富含钛化合物(NiTi、Ti2Ni 和 Ti2Co)的体心立方(BCC)固溶体、BCC + Ti0.85Al0.15 和 Ti0.85Al0.15。涂层的平均晶粒大小为 3.9 μm,BCC 相的位错密度为 1.51 × 1014/m²。由于存在化合物、细晶粒和高位错密度,涂层的平均纳米硬度达到了 8.39 ± 0.29 GPa,比 Ti-6Al-4 V 高出约 1.8 倍。此外,涂层的磨损率为 22.28 ± 4.56 × 10- 6 mm3/(N-m),比 Ti-6Al-4 V 降低了 65.5%。

Enhancing the surface properties of Ti-6Al-4V with high entropy alloy coating prepared by electron beam cladding

A high entropy alloy (HEA) coating was applied on Ti-6Al-4 V by electron beam cladding Al7(CoFeNi)86Ti7 HEA powder. The optimal electron beam cladding parameters, determined through orthogonal experimental analysis, were: 64 kV accelerating voltage, 12 mA welding beam current, and 3 s scanning time. Microstructure, phase composition, nano-hardness and wear resistance of the coating prepared using optimal parameters were investigated. The primary phases in the top, middle, and bottom regions of the coating were identified as body-centered cubic (BCC) solid solution with Ti-rich compounds (NiTi, Ti2Ni, and Ti2Co), BCC + Ti0.85Al0.15, and Ti0.85Al0.15, respectively. The coating had an average grain size of 3.9 μm, and the dislocation density of the BCC phase was 1.51 × 1014/m². Due to the presence of compounds, fine grains, and high dislocation density, the coating achieved an average nano-hardness of 8.39 ± 0.29 GPa, approximately 1.8 times higher than that of Ti-6Al-4 V. Additionally, the wear rate of the cladded coating was 22.28 ± 4.56 × 10− 6 mm3/(N·m), representing a 65.5% reduction compared to Ti-6Al-4 V.
