Corrosion Resistance of Ternary Ni-Ta-Sn Amorphous Alloy

The ribbon Ni-Ta-Sn amorphous alloy was prepared by means of single-roller melt-spinning technique in an argon atmosphere.The corrosion behavior of Ni-Ta-Sn amorphous alloy in several corrosives media was studied by weight loss measurement and potentiodynamic polarization method at room temperature.The results was compared with those of Zr-Ti-Cu-Ni-Be amorphous alloy and 1Cr18Ni9Ti stainless steel .The experiments showed that corrosion resistance of Ni-Ta-Sn amorphous was better than that of Zr-Ti-Cu-Ni-Be and much better than that of 1Cr18Ni9Ti stainless steel.
