Title:
MEMBER FOR NONFERROUS MOLTEN METAL
Document Type and Number:
Japanese Patent JP2000064060
Kind Code:
A
Abstract:

To provide a member for nonferrous molten metal having erosion resistance even in the case of being immersed in or repeatedly brought into contact with nonferrous molten metal and safely usable by using a ferrous material as a base material.

On the surface of a ferrous base material 1, an intermediate layer 2 of an Al-Fe alloy metallically bonded to the ferrous base material surface is formed, and, moreover, the surface of the intermediate layer 2 of the Al-Fe alloy is coated with a ceramic layer 3. The ceramic layer 3 contains flat ceramic powder, is bonded with fused glass or bonded with a ceramic bonding material essentially consisting of silicate or phosphate and is fused to cover on the Al-Fe alloy layer as the substrate. The flat ceramic powder is composed of the powder of one or ≥ two kinds among silicon carbide flat alumina and mica and is contained by 20 to 70 wt.% in the ceramic layer. As the nonferrous molten metal, mainly, the molten metal of an aluminum alloy, a zinc alloy, a copper alloy or the like is used as the object.
