Abstract
The invention relates to powder and none ferrous metallurgy, in particular, to sintered iron-based anti-friction materials for use in fabricating details used in friction units. It is characterized in that a mechanically activated sintered iron-graphite composite for female dies of combined casting and rolling for pressing based on iron and carbon-containing component comprises casting and cryptocrystalline graphites as a carbon-containing component with the following component ratio, wt.%: iron - 96.5-98.5, casting graphite - 0.2-0.8, cryptocrystalline graphite - 1.3-1.8. The proposed composition of a sintered iron-graphite composite provides to preserve physical and mechanical properties at a substantial charge lower cost and due to mechanical activation of graphite powder durability of technological process and input of materials are significantly shortened, thus reducing total costs.
Description
(57) Изобретение относится к порошковой и цветной металлургии, в частности к спеченным антифрикционным материалам на основе железа, предназначенным для изготовления деталей, используемых в узлах трения. Достигается это тем, что механоактивированный, спеченный, железографитовый композит для пресс-матриц совмещенного литья и прокатки прессования на основе железа и углеродсодержащего компонента в качестве углеродсодержащего компонента содержит литейный и скрытокристаллический графиты при следующем соотношении компонентов, мас.%: железо - 96,5-98,5, литейный графит - 0,2-0,8, скрытокристаллический графит - 1,3-1,8. Предложенный состав спеченного, железографитового композита позволяет сохранить высокие физико-механические свойства при значительном удешевлении стоимости шихты, а за счет механоактивации графитовых порошков удается значительно сократить длительность технологического процесса и расход материалов, а, следовательно, и сопутствующие этому затраты.(57) The invention relates to powder and non-ferrous metallurgy, in particular to sintered antifriction materials based on iron, intended for the manufacture of parts used in friction units. This is achieved by the fact that the mechanically activated, sintered, iron-graphite composite for press-matrices of combined casting and rolling of presses based on iron and a carbon-containing component contains casting and cryptocrystalline graphites as the carbon-containing component in the following ratio of components, wt.%: Iron - 96.5- 98.5, foundry graphite - 0.2-0.8, cryptocrystalline graphite - 1.3-1.8. The proposed composition of the sintered, iron-graphite composite allows to maintain high physical and mechanical properties with a significant reduction in the cost of the charge, and due to the mechanical activation of graphite powders, it is possible to significantly reduce the duration of the process and the consumption of materials, and, consequently, the associated costs.
