ABSTRACT:
Disclosed is a sintered iron alloy, a method of manufacturing the same, a powdered mixture used for manufacturing the same and a method of modifying the surface of the iron alloy. The sintered iron alloy is produced by compacting a powdered mixture comprising: boron or boron compound which is selected from the group consisting of boron oxide, boron sulfide, boron halide, boron hydride, boric acid, borate and tetrafluoroborate; 0.1 to 2.0% by weight of graphite; and iron, and sintering it. Alternatively, the iron alloy is produced by impregnating a modifier containing boron or boron compound, into a green compact, a presintered compact or sintered body which contains iron and carbon, and heating it.
