Study on corrosion resistance of Al-Cr alloy prepared by solid-liquid mixed casting technology
Al-10Cr alloy is prepared by mixed liquid-solid casting.The corrosion behavior of Al-10Cr alloy prepared by solid-liquid mixed casting technology has been analyzed by potentiondynamic polarization curves.It is found that the alloy with uniformfine grain can be obtained under the conditions of 40% powder addition as well as powder granulannity of 74～175 μm.The results also show that the corrosion resistance of Al-Cr alloy prepared by solid-liquid mixed casting technology is superior to that of semisolid casting technologies.
