The effect of RE-modification and Sr-modification on the surface oxide film of A356 aluminum alloy melt was investigated in this paper.

通过X射线衍射、扫描电镜等方法分析了变质元素对A356铝合金表面氧化膜成分及形貌的影响。

This is because the oxide film at the A356 melt surface was almost composed of SrO, but this oxide make the surface oxide film looser had been loosened and cracked owing to the enrichment of the Strontium of t.

这是因为Sr加入到A356合金后,在铝熔体表面氧化膜中,出现有锶的氧化物。
