LOW-MELTING-POINT MOLTEN METAL PROCESSING MEMBER

摘要

To improve the erosion resistance of a processing member for low-melting-point molten metals such as aluminum having a low melting point by suppressing the occurrence of cracks in a surface protective layer or separation of a coating layer. Provided is a low-melting-point molten metal processing member which comprises: a base that is formed of titanium; an titanium oxide layer that is arranged on the surface of the base and has a thickness of 2-20 μm; and an oxygen enriched layer that is formed of an α phase having a higher oxygen concentration than the base and is arranged below the titanium oxide layer, while having a thickness of 20-200 μm. This low-melting-point molten metal processing member exhibits excellent erosion resistance against low-melting-point molten metals such as aluminum having a low melting point.
