Abstract (en)
[origin: US4839138A] To make a sintered molding which is provided with at least one molybdenum containing wear-resisting facing (2), a low-alloy iron powder (10) which is intended to form the base of the molding and a carbon-free metal powder mixture (3) which is intended to form the wear-resisting facing (2) and consists of unalloyed iron particles and unalloyed molybdenum particles are jointly molded in a common mold (9) to form a molding, which is subsequently sintered. In order to prevent a mixing of the two metal powder layers, the metal powder which is intended to form the wear-resisting facing (2) is separately compacted to form a compact (5) before the mold (9) is charged with the iron powder (10) that is intended to form the base of the molding.
