| 摘 要： | 研究了放电等离子烧结(FeCoNiCr)100-xMnx(x=4,8,12,20)高熵合金的组织结构及在NaCl和NaOH溶液中的耐腐蚀性能。结果表明,(FeCoNiCr)100-xMnx合金主要由FCC单相组织和少量BCC相组成。(FeCoNiCr)88Mn12合金在3.5wt%NaCl 溶液中具有最好的耐腐蚀性能。Mn的添加使合金在1 mol NaOH 溶液中耐腐蚀性增强。退火对合金在1 mol NaOH 溶液中抗腐蚀性能影响不大。(FeCoNiCr)100-xMnx合金在3.5wt%NaCl溶液和1 mol NaOH溶液中的抗腐蚀性能均优于304S不锈钢。

| Abstract: | Microstructure and corrosion resistance in NaCl and NaOH solutions of the (FeCoNiCr)100-xMnx(x=4,8,12,20) high entropy alloys prepared by spark plasma sintering were studied. The results show that (FeCoNiCr)100-xMnx alloys are mainly composed of FCC single phase structure and a small amount of BCC phase. (FeCoNiCr)88Mn12 alloy has the best corrosion resistance in 3.5wt%NaCl solution. The addition of Mn enhances the corrosion resistance of the alloy in 1 mol NaOH solution. Annealing has little effect on corrosion resistance of the alloy in 1 mol NaOH solution. The corrosion resistance of the (FeCoNiCr)100-xMnx alloys in 3.5wt%NaCl solution and 1 mol NaOH solution is better than that of the 304S stainless steel. |
