Abstract
A production method for a sintered member includes preparing a raw powder, compacting the raw powder into a green compact having pores at the surface thereof, and sintering the green compact into a sintered compact. The production method also includes sealing the pores exposed at the surface of the sintered compact by at least one of plastically deforming and melting the surface of the sintered compact. The production method further includes forging the sintered compact by using a lubricant after the sealing.
