METHOD FOR MANUFACTURING MEMBER HAVING WEAR RESISTANT INNER PERIPHERAL SURFACE

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing a member having a wear resistant inner peripheral surface, by which the load in an additional process is reduced. SOLUTION: The method for manufacturing a member having a wear resistant inner peripheral surface includes: forming a wear resistant hardened layer on the outer peripheral surface of a sacrificial member having an columnar outer peripheral surface; then fitting the sacrificial member on which the wear resistant hardened layer is formed into the inner diameter part of a cylindrical base material having an inner diameter corresponding to the outer diameter of the wear resistant hardened layer to form a composite member; heating the composite member to form a liquid phase at least partially in the wear resistant hardened layer and to cause the diffusion of constitution elements between the inner diameter part of the base material and the wear resistant hardened layer; and removing the sacrificial member.
