摘要

研究了不同Ti含量的AlFeCuCoNiCrTix多主元高熵合金的组织结构及其在0.5mol/L的H2SO4溶液和1mol/L的NaCl溶液中的电化学性能,并与304不锈钢进行了对比。结果表明,随着Ti元素的添加,合金的组织结构仍然主要由BCC相和FCC相组成。极化曲线结果表明,在0.5mol/L的H2SO4溶液中的,与304不锈钢相比,该系合金具有较低的腐蚀速率;在1mol/L的NaCl溶液中,该系合金的腐蚀速率与304不锈钢相当,但是其抗孔蚀的能力要优于304不锈钢。

Abstract

Microstructure of AlFeCuCoNiCrTix （atom weight, x=0.5, 1.0, 1.5） high entropy alloys was observed, and electrochemical behavior of the high entropy alloy was examined and compared with that of commercial 304 stainless steel in o.5 mol H2SO4 solution and 1 mol NaCl solution. The results reveal that the AlFeCuCoNiCrTix （atom weight, x=0.5, 1.0, 1.5） high entropy alloys is mainly composed of fcc structure and bcc structure. Polarization curves show that compared with that of 304 stainless steel, the alloys exhibits lower corrosion rate in 0.5 mol H2SO4 solution, however the pitting corrosion resistance is superior to that of 304 stainless steel in 1 mol NaCl solution.
