FIELD: railway and city electrified transport.
SUBSTANCE: invention relates to methods of manufacture of devices for contact current collecting, and it can be used in manufacture of contact slipper for railway sand city electrified transport. According to proposed method, binder and graphite filler are mixed, and article is pressed from said mixture at temperature of 150-170°C at specific pressure of 300-400 kgf/sq.cm with 3-5 min holding under said pressure and subsequent thermal treatment of articles. Thermal treatment is carried out in steps including quick heating to 80-100°C and slow heating at decreasing rate to 150-200°C, holding at this temperature and slow natural cooling.
EFFECT: improved mechanical properties of contact slippers.
