| 摘 要： | 具有高的玻璃形成能力Fe基非晶合金(Fe40Ni40P14B6)100-xGax(x=0,2.5和4.5)是利用单辊铜轮旋转的方法制备出来的.用电化学的方法研究非晶合金(Fe40Ni40P14B6)100-xGax(x=0,2.5和4.5)分别在1 mol/L和3 mol/L的HCl溶液中腐蚀行为,结果表明:非晶合金(Fe40Ni40P14B6)100-xGax(x=0,2.5和4.5)在HCl溶液中具有较高的腐蚀特性,并且随着Ga含量的增加,铁基非晶合金的耐腐蚀性能增加.另外,非晶合金(Fe40Ni40P14B6)100-xGax(x=0,2.5和4.5)与不锈钢(1Cr18Ni9Ti)分别在1 mol/L和3 mol/L的HCl溶液中的腐蚀行为相比,非晶合金的耐腐蚀性能更好.

| Abstract: | The ribbon Fe-based amorphous alloy with high glass-forming ability in ( Fe_(40)Ni_(40)P_(14)B_6)_(100-x)Ga_x(x=0, 2.5 and 4.5 )amorphous alloy is prepared by means of single-roller melt-spinning technique in an argon atmosphere. The electrochemical corrosion behavior of (Fe_(40)Ni_(40)P_(14)B_6)_(100-x)Ga_x(x=0,2.5 and 4.5 )amorphous alloy is spontaneously passivated in 1 mol/L and 3 mol/L HCl solutions. With the increase of Ga content in the alloys,the corrosion resistance of ribbon amorphous alloys improves. In addition, the electrochemical corrosion behavior of ( Fe_(40)Ni_(40)P_(14)B_6)_(100-x)Ga_x(x=0, 2.5 and 4.5 )amorphous alloy and 1Cr18Ni9Ti stainless steel is studied by electrochemical method in 1 mol/L and 3 mol/L HCl solutions respectively, which show that the corrosion resistance of amorphous alloy is much better than stainless steel. |
