Abstract

Изобретение относится к порошковой металлургии, в частности к композициям, используемым преимущественно для изготовления контактных вставок городского электротранспорта (троллейбусов). Техническим результатом является повышение прочности контактных вставок. Это достигается тем, что композиция для изготовления контактных вставок, включающая, мас.%: электрографит 67-75, кокс прокаленный 5-12, фенолформальдегидную смолу 11-20, стеарат цинка 0,5-2,0, политетрафторэтилен 0,5-8, дополнительно содержит нанопорошок меди в количестве 0,5-2.The invention relates to powder metallurgy, in particular to compositions used mainly for the manufacture of contact inserts urban electric vehicles (trolley buses). The technical result is to increase the strength of the contact inserts. This is achieved by the fact that the composition for the manufacture of contact inserts, including, wt.%: Electrographite 67-75, calcined coke 5-12, phenol-formaldehyde resin 11-20, zinc stearate 0.5-2.0, polytetrafluoroethylene 0.5-8 It additionally contains copper nanopowder in the amount of 0.5-2.
