Abstract
Description
Изобретение относится к области порошковой металлургии и касается спеченных сплавов на основе меди, которые могут быть использованы в приборостроении, машиностроении.The invention relates to the field of powder metallurgy and relates to sintered alloys based on copper, which can be used in instrumentation, mechanical engineering.
Известен спеченный сплав на основе меди, содержащий, мас.%: олово 3,0-6,0; цинк 3,5-8,5; свинец 3,5-7,5; никель 0,1-1,5; железо 0,1-1,0; медь - остальное [1].Known sintered alloy based on copper, containing, wt.%: Tin 3.0-6.0; zinc 3.5-8.5; lead 3.5-7.5; nickel 0.1-1.5; iron 0.1-1.0; copper - the rest [1].
Задачей изобретения является повышение твердости сплава.The objective of the invention is to increase the hardness of the alloy.
Технический результат достигается тем, что спеченный сплав на основе меди, содержащий цинк, никель, железо, дополнительно содержит марганец, ванадий и церий при следующем соотношении компонентов, мас.%: цинк 6,5-8,5; никель 0,5-1,5; железо 0,2-0,3; марганец 4,0-6,0; ванадий 0,15-0,2; церий 0,15-0,2; медь - остальное.The technical result is achieved in that the sintered alloy based on copper, containing zinc, nickel, iron, additionally contains manganese, vanadium and cerium in the following ratio of components, wt.%: Zinc 6.5-8.5; nickel 0.5-1.5; iron 0.2-0.3; manganese 4.0-6.0; vanadium 0.15-0.2; cerium 0.15-0.2; copper is the rest.
В таблице приведены составы спеченного сплава на основе меди для деталей, работающих в условиях трения.The table shows the compositions of the sintered alloy based on copper for parts operating in friction conditions.
Олово и цинк уменьшают плотность сплава, незначительно упрочняют его. Никель, железо, марганец улучшают антифрикционные свойства сплава, повышают твердость. Ванадий способствует измельчению зерна, выравниванию свойств изделий в различных по толщине сечениях. Церий нейтрализует вредное влияние примесей мышьяка.Tin and zinc reduce the density of the alloy, slightly harden it. Nickel, iron, manganese improve the antifriction properties of the alloy, increase hardness. Vanadium contributes to the grinding of grain, leveling the properties of products in sections of various thicknesses. Cerium neutralizes the harmful effects of arsenic impurities.
Компоненты сплава (порошки) дозируют в требуемых количествах, смешивают, прессуют под давлением 3,5-3,8 т/см2 в заготовки и спекают в среде инертного газа при температуре 1100°C.Alloy components (powders) are dosed in the required quantities, mixed, pressed under pressure of 3.5-3.8 t / cm 2 into billets and sintered in an inert gas medium at a temperature of 1100 ° C.
