| 英文摘要 | Effect of Cu content on the microstructure, corrosion resistance, and antifouling performance of the CoCrFeNiCux (x = 0, 0.2, 0.5) high-entropy alloys (HEAs) in 3.5 wt% NaCl solution was examined. For the CoCrFeNiCux HEA without Cu addition, no apparent preferred orientation was observed though {111} plane displays the highest peak intensity. For the Cu0.2 and Cu 0.5 HEAs, the intensity of {111} peak is weakened significantly and {100} plane becomes the dominant peak, which leads to preferred orientation. Cu0 and Cu 0.2 HEAs are composed of single FCC phase. For the Cu0.5 HEA, Cu atoms tend to segregate to interdendritic region and precipitates can be observed in both dendritic and interdendritic regions. The corrosion resistance of the CoCrFeNiCux HEAs is decreased with increasing Cu content, which is caused by the increased CuO content in the passivation film, increased surface energy by lattice distortion by Cu atoms and the preferred orientation, and the reactions between Cu atoms and Cl-. The antimicrobial rate of the CoCrFeNiCu0.2 and the CoCrFeNiCu0.5 HEAs can be increased to 99.57% and 99.99%, respectively, which is much higher than the antimicrobial rate of 51.60% for the HEA without Cu addition. |
