FIELD: process engineering.
SUBSTANCE: invention relate to powder metallurgy, particularly to production of iron-based antifriction parts for machine building. Iron-based burden is compacted and sintered to produce sintered parts. Sintered parts are placed in reactor above heated solution of zinc phosphate, reactor is sealed and evacuated to 1 mm Hg. Then the part is dipped into aforesaid solution and kept therein for about one hour. Prior to or after phosphate treatment, calibration is performed. Sintered antifriction part coated with zinc phosphate is impregnated with oil.
EFFECT: longer life of antifriction part in self-lube operation.
