Tribological properties of the frictional coverings modified by the rare-earth concentrate from the Tomtor field (Yakutia)

Comparative researches of chemical and phase composition, structure and micro hardness of gas-thermal coverings from experimental powder from wires with modifying mineral additives are conducted. The studied regularities of wear the coverings from powder from wires at a sliding friction showed possibility of using the mineral compositions from fields in Sakha Republic (Yakutia) as additives in wearproof powder materials for receiving coverings with the increased operational properties.
