MACHINE COMPONENT USING POWDER COMPACT AND METHOD FOR PRODUCING SAME

摘要

According to the present invention, a machine component having a radial crushing strength of more than 100 MPa is produced by: obtaining a powder compact by press molding a starting material powder which is mainly composed of a metal powder that is capable of forming an oxide film; and then forming an oxide film between particles of the metal powder that constitutes the powder compact by means of a water vapor treatment.
