摘要:: 研究了块状金属玻璃(Fe1-x,Cox)76Mo4(P0.45C0.2B0.2Si0.15)20(76x=0、10和20)的化学腐蚀行为.利用电化学腐蚀实验的方法,考察了该Fe基决状金属玻璃在不同浓度的HCl溶液中的极化电位和极化电流,从所测得的电化学极化曲线分析了其电化腐蚀特征;并采用失重法测定了该金属玻璃在不同浓度的HCl溶液中的腐蚀速率,腐蚀率低于0.08 g·m-2·h-1.结果表明:所研究的Fe基块状金属玻璃合金系在HCl溶液中具有优异的耐蚀性;并且随着Co含量的增加,相应的金属玻璃的耐腐蚀性能也进一步提高.

Abstract:: The chemical corrosion behavior of bulk metallic glass (Fe1-x, Cox) 76Mo4 (P0.45C0.2B0.2Si0.15)20 (76x=0, 10 and 20) was studied. The polarization potential and polarization current of the Fe-based junction metal glass in HCl solution at different concentrations were investigated by electrochemical corrosion experiment, and the electrochemical corrosion characteristics were analyzed from the measured electrochemical polarization curve. The corrosion rate of the metal glass in HCl solution at different concentrations was determined by weight loss method, and the corrosion rate was lower than 0.08 g·m-2·h-1. The results showed that the studied Fe-based bulk metal-glass alloy system had excellent corrosion resistance in HCl solution. And with the increase of Co content, the corrosion resistance of the corresponding metal glass is further improved.
