    摘要:

    采用電化學(xué)極化曲線和電化學(xué)阻抗(EIS)測試方法研究Fe41Co7Cr15Mo14C15B6Y2塊體非晶合金在0.5，1，2以及4 mol/L HCl溶液中的腐蝕行為，并比較了1 mol/L HCl 溶液中非晶合金和不銹鋼的腐蝕行為。極化曲線測試結(jié)果表明，F(xiàn)e41Co7Cr15Mo14C15B6Y2塊體非晶合金在各種濃度的HCl溶液中都具有很好的耐蝕性，陽極極化曲線表現(xiàn)出明顯的鈍化特征。隨著HCl溶液濃度的增大，其耐蝕性能逐漸下降。在1 mol/L HCl溶液中，非晶合金的自腐蝕電位高于不銹鋼，自腐蝕電流密度比不銹鋼小1個數(shù)量級。EIS結(jié)果顯示，在開路電位下，F(xiàn)e41Co7Cr15Mo14C15B6Y2非晶合金和不銹鋼的Nyquist圖均由單一的容抗弧構(gòu)成，但非晶合金的電化學(xué)轉(zhuǎn)移電阻Rt比不銹鋼的大2個數(shù)量級，這一結(jié)果與極化曲線結(jié)果一致，說明非晶合金在HCl溶液中的耐蝕性能優(yōu)于不銹鋼

    Abstract:

    Corrosion behaviors of bulk amorphous Fe41Co7Cr15Mo14C15B6Y2 alloy in 0.5, 1, 2, 4 mol/L HCl solutions were studied by potentiodynamic polarization experiments and electrochemical impedance spectroscopy (EIS). Moreover, the corrosion behaviors of amorphous alloy and stainless steel were compared in 1 mol/L HCl solution. The results of potentiodynamic polarization experiment show that the amorphous Fe41Co7Cr15Mo14C15B6Y2 alloy has excellent corrosion resistance in different concentration of HCl solutions and its anodic reaction has a passive character. With the concentration of the HCl solutions increasing, the corrosion resistance of the amorphous alloy decreases. The results of potentiodynamic polarization experiments in 1 mol/L HCl solution show that the corrosion potential of the amorphous alloy is higher and the corrosion current density is lower than those of stainless steel. EIS experimental results show that the Nyquist figures of amorphous alloy and stainless steel are both composed of one single semi-circle in the state of open circuit potential. But the amorphous alloy has a higher charge transfer reaction resistance than the stainless steel. This result is accord with that of potentiodynamic polarization. The present results demonstrate that the corrosion resistance of bulk amorphous Fe41Co7Cr15Mo14C15B6Y2 alloy is much better than stainless steel.
