Abstract

PURPOSE:To prevent molten metal from permeating into the inside of a structural body and, besides, to improve the wear resistance of the surface, by forming a nitride layer on the surface of the sintered sistructural body of metal such as mold for iron die casting and thus by sealing hermetically the surface pores.
