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0.01mol/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。
（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.
