- 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.
