Abstract

PURPOSE:To improve characteristic of surface layer compared with inner layer by adding much quantity of Ni compared with the other part by forming sufficient layer thickness at part of the whole surface layer in an iron series material-made casting having ferritic matrix structure. CONSTITUTION:A Ni foamed body 5 is wound and fixed around a core 4, and material equivalent to JIS FCD 50 (spheroidal graphite cast iron) is poured into a cavity 3 through a sprue 2. Structures (matrix phase) at inner wall part A (position setting Ni foamed body 5) of the obtd. cylindrical casting product 6 are martenstic phase in the range where Ni-added quantity is relatively much, mixed phase of martensite, pearlite and ferrite in the range where Ni-added quantity is relatively less and mixed phase of pearlite and ferrite at further deeper position.
