Influence of Zr Content on Thermal Stability and Corrosion Behavior of (Al86Ni9La5)100-xZrx Amorphous Alloys

摘要:

用单辊甩带法制备出组分为(Al86Ni9La5)100-xZrx (x=0, 3, 5, 7, 10)的合金薄带。用X射线衍射(XRD)仪和示差扫描量热计(DSC)对这些薄带的非晶特性和热稳定性进行分析；在0.01 mol/L的碱性NaCl溶液中，对(Al86Ni9La5)100-xZrx (x=0, 3, 5, 7) 甩带试样的电化学腐蚀行为进行研究。结果表明，(Al86Ni9La5)100-xZrx (x=0, 3, 5, 7, 10)的合金薄带中，组分为(Al86Ni9La5)95Zr5样品的非晶热稳定性最好，随着Zr含量的增加，(Al86Ni9La5)100-xZrx的抗电化学腐蚀性能增强

Abstract:

(Al86Ni9La5)100-xZrx alloy ribbons (x=0, 3, 5, 7, 10) were prepared by melt-spinning. The amorphous characteristics and thermal stability of the ribbons were analyzed by X-ray diffraction (XRD) and differential scanning calorimeter (DSC). The corrosion behavior of (Al86Ni9La5)100-xZrx (x=0, 3, 5, 7) amorphous samples were investigated by electrochemical techniques in 0.01 mol/L NaCl alkaline solution. The results reveal that among the (Al86Ni9La5)100-xZrx (x=0, 3, 5, 7, 10) ribbons the (Al86Ni9La5)95Zr5 exhibits the best thermal stability, and with the content of Zr increasing, the electrochemical corrosion resistance is also enhanced
