摘要
The effect of hot extrusion and addition of Y element on the corrosion behavior of MgeY alloy was investigated by weight loss,immersion tests and potentiodynamic polarization measurements.The results showed that the grains became finer and uniform by increasing Y element,after extrusion.The corrosion resistance of MgeY alloy after extrusion was deteriorated with the addition of Y element and corrosion rates decreased in the following order:Mge13.78Y>Mge7.46Y>Mge5.23Y.
