Experimental Investigation of the Erosion Resistance of Crucible Material to Melted Aluminum
The structure of stainless steel, nodular graphite cast iron, grey iron and hypereutectic steel was studied, the effect of structure on the erosion resistance to the melted aluminum was analyzed, and a set of data of resistance to melted aluminum erosion for various materials was obtained through test. Based on these results, a ceramic-metallic composite was designed, and the preparation technology was discussed. The AI2O3 in ceramic can resist the erosion of melted aluminum to the matrix. The result shows that the method can enhance the erosion resistance to the melted aluminum significantly.
