Beschreibung
Zusammenfassung:	Provided is a method of manufacturing a machine part having a radial crushing strength of 120 MPa or more, including: a compression molding step of compressing raw material powder including, as a main component, metal powder that is capable of forming an oxide coating and has a pure iron powder content ratio of 95 mass % or more, to thereby obtain a green compact (10) having a predetermined shape; and a coating forming step of causing the metal powder to react with an oxidizing gas while heating the green compact (10) at a temperature lower than a sintering temperature of the metal powder in an oxidizing gas atmosphere, to thereby obtain a reinforced green compact (11) in which the oxide coating (5) is formed between particles of the metal powder.
