Abstract

With the increase in studies on high-entropy alloys and their impressive structural properties, the preparation processes and applications of high-entropy alloys have become a popular research topic in metallic materials. In this paper, the preparation of FeCrNiCoMnSi_0.1 high-entropy alloy coatings was carried out by the follow-welding high-frequency power ultrasonic impact composite TIG arc melting process, the effects of different power ultrasonic impacts on the microstructure and properties of the coatings are investigated. The results showed that the average grain size is reduced by 74 % (from 278 μm to 72 μm), the average microhardness is increased by 41 % from 568 HV₁ to 807 HV₁, the abrasion resistance is improved by 68 % under the effect of ultrasonic impact. The ultrasonic impact treatment process can effectively refine the microstructure of the coatings and improve the strength of grain boundaries. The corrosion resistance of the coating in 3.5 wt% NaCl solution is enhanced by 65 %, the corrosion type was changed from intergranular corrosion to uniform corrosion. This is mainly caused by the ultrasonic impact treatment which suppresses the elemental segregation of Cr and Mn and improves the grain boundary strength.

TIG电弧熔炼和高频超声冲击焊接制备FeCrNiCoMnSi0.1高熵合金涂层的组织、力学和腐蚀性能

随着对高熵合金及其优异结构性能研究的增加，高熵合金的制备工艺及其应用已成为金属材料领域的研究热点。本文采用后续焊接高频功率超声冲击复合TIG弧熔工艺制备了FeCrNiCoMnSi0.1高熵合金涂层，研究了不同功率超声冲击对涂层组织和性能的影响。结果表明:在超声冲击作用下，合金的平均晶粒尺寸从278 μm减小到72 μm，平均显微硬度从568 HV1提高到807 HV1，提高了41%，耐磨性提高了68%。超声冲击处理工艺能有效细化涂层组织，提高晶界强度。涂层在3.5 wt% NaCl溶液中的耐蚀性提高65%，腐蚀类型由晶间腐蚀转变为均匀腐蚀。这主要是由于超声冲击处理抑制了Cr和Mn的元素偏析，提高了晶界强度。
