Abstract The effects of Sb contents on the microstructure and corrosion behavior in NaCl solution of as-cast AM50-Y alloy were studied. The results show that with the addition of Sb, YSb phase forms preferentially. As Sb contents increase, the size and amount of the polygonal Al2Y reduce, while the amount of YSb phase increases, which aggregates and increases in size when Sb content is up to 1%. The corrosion rate and corrosion current of the alloys are improved, whereas the oxide film resistance and electric double layer capacitance are reduced with the increase of Sb. The alloy with 1% Sb has the worst corrosion resistance, and the corrosion rate is up to 2.65 mg·cm−2·d−1, which is increased by nearly 2 times compared with the alloy without Sb addition.
