EROSION RESISTANT MEMBER FOR NON-FERROUS MOLTEN METAL

摘要

PROBLEM TO BE SOLVED: To provide an erosion resistant member for non-ferrous molten metal, the member that has comparatively inexpensive manufacturing cost and that is superior in wear resistance and erosion resistance.;SOLUTION: The erosion resistant member for non-ferrous molten metal is characterized in that a coating layer made of a high-speed steel based alloy is provided at least on a part of the surface of a base material composed of an iron-based or steel-based material and that a nitride layer is formed on the surface of the coating layer. The erosion resistant member is also characterized in that carbide such as MC-, M₂C-, M₆C-, M₇C₃-, M₄C₃- and M₂₃C₆-based carbide contained in the coating layer is not more than 25% in the sum total of the area ratios.;COPYRIGHT: (C)2005,JPO&NCIPI
