Abstract

In the process of smelting and processing of magnesium alloy, some non-metallic inclusions may be introduced which reduce its properties and quality. The composition and distribution of non-metallic inclusions in magnesium alloy were analyzed by SEM and EDS. The feasibility and purification effect of several purification methods, including sedimentation, fluxing and gas adhering, were analyzed and discussed. The purification effect of ceramic foam filter and addition of rare earths is discussed. Each method has its own advantages and disadvantages. In practice, several methods are used together to reach better purification effect.
