摘要/Abstract

摘要： 对机械合金化Ni₆Cr₄W_1.5Fe₉Ti高熵合金粉末进行激光熔化沉积,制备了该高熵合金的熔覆涂层,研究了机械合金化时间对涂层显微组织和耐蚀性能的影响。结果表明,机械合金化时间的增加可促进合金粉末成分的均匀化,且有利于涂层的致密化及其组织的晶粒细化。机械合金化棒磨4 h后的高熵合金粉末中,各组元均匀分布,并形成了FCC+BCC的双相固溶体结构;通过激光熔化沉积后,双相固溶体结构转变为FCC单相固溶体结构,组织主要由4~6 μm的等轴晶和少量胞状晶组成。机械合金化棒磨4 h粉末制备熔覆涂层的致密度和硬度最高、耐蚀性最佳,其耐蚀性相较于棒磨0 h粉末制备熔覆涂层提升了近两个数量级。

Abstract: Clad coating of mechanical alloyed Ni₆Cr₄W_1.5Fe₉Ti high-entropy alloy powder was prepared by laser melting deposition. The effect of mechanical alloying time on microstructure and corrosion resistance of the coating was studied. The results show that the increase of mechanical alloying time can promote the homogenization of alloy powder composition, the densification of coating and the grain refinement of microstructure. After mechanical alloying rod grinding for 4 h, the components of high-entropy alloy powder are evenly distributed, and the FCC+BCC two-phase solid solution structure is formed. After laser melting deposition, the structure of two-phase solid solution is transformed into FCC single-phase solid solution, which is mainly composed of 4-6 μm equiaxed crystals and a small amount of cellular crystals. Among them, the coating prepared by powder mechanical alloying rod grinding for 4 h has the highest density, hardness and the best corrosion resistance, and its corrosion resistance is nearly two orders of magnitude higher than that of the coating prepared by powder mechanical alloying rod grinding for 0 h.

Key words: mechanical alloying, high-entropy alloy, laser melting deposition, microstructure, corrosion resistance
