Beschreibung
Zusammenfassung:	FIELD: production of bimetallic anti-friction materials, namely processes for sintering powder systems, possibly in machine engineering for making friction assemblies and retainers of rolling bearings. ^ SUBSTANCE: process comprises steps of bronzing sheet of low-carbon steel; sintering to it bronze-brass gauze and filling its pores with PTFE; simultaneously performing bronzing of low-carbon steel and scorching of bronze-brass gauze to bronzed steel in sealed container at temperature 850 - 860°C; filling pores of gauze with bronze powder and subjecting semi-finished material to heat treatment in sealed container at temperature 880 - 900°C; filling pores of bronze layer with ultra-finely divided PTFE by rubbing and then rolling material between rollers. ^ EFFECT: simplified manufacturing process, improved technical properties of material.
