Erosion Wear Resistance of Al0.5FeCoCrNi High-Entropy Alloy in Liquid-Solid Two-Phases Flow

  • 摘要: 采用电弧炉熔炼制备了Al0.5FeCoCrNi高熵合金,并对其在800,1 000 ℃进行热处理,研究了热处理以及液固两相流中冲蚀参数(冲蚀角度、冲蚀速度、冲蚀时间)对其冲蚀磨损性能的影响,并与00Cr13Ni5Mo不锈钢的冲蚀磨损性能进行了对比。结果表明:在冲蚀角度为45°时,两种材料的质量损失率均最大,呈现出韧性材料的冲蚀磨损特性;随着冲蚀时间延长和冲蚀速度增大,两种材料的质量损失率均显著增大;热处理能提高高熵合金的硬度和冲蚀磨损性能,且800 ℃热处理后的便佳;高熵合金的冲蚀磨损性能优于不锈钢的;高熵合金的冲蚀磨损机制以切削、犁削和塑性变形为主,不锈钢的则主要为切削和挤压变形,且伴有碎裂的剥落。
    Abstract: Al0.5FeCoCrNi high-entropy alloy was prepared by arc-melting and then was heat-treated at 800, 1 000 ℃. The effects of heat treatment and erosion angle, erosion rate and erosion time in liquid-solid two-phases folw on erosion wear resistance of the high-entropy alloy were studied, and then were compared with 00Cr13Ni5Mo stainless steel. The results show that the mass loss rate of the two materials were largest when the erosion angle was 45°, and they exhibited the erosion wear characteristics of ductile materials. Mass loss rate of the two materials all increased dramatically with the increase of erosion time and erosion rate. Heat treatment could increase the hardness and erosion wear resistance of the high-entropy alloy, and the hardness and erosion wear resistance heat-treated at 800 ℃ were relatively good. The erosion wear resistance of the high-entropy alloy was better than the stainless steel. The erosion wear mechanism of the high-entropy alloy was dominated by cutting, plough cut and plastic deformation, and that of the stainless steel was dominated by cutting, extrusion deformation and peeling off.
