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 олово, цинк, никель, железо, дополнительно содержит хром, молибден, вольфрам при следующем соотношении компонентов, мас.%: олово 4,0-6,0; цинк 2,0-3,0; никель 0,3-0,7; железо 0,3-0,7; хром 0,3-0,4; молибден 0,2-0,3; вольфрам 0,05-0,1; медь - остальное.The technical result is achieved in that the sintered alloy based on copper, containing tin, zinc, nickel, iron, additionally contains chromium, molybdenum, tungsten in the following ratio of components, wt.%: Tin 4.0-6.0; zinc 2.0-3.0; nickel 0.3-0.7; iron 0.3-0.7; chrome 0.3-0.4; molybdenum 0.2-0.3; tungsten 0.05-0.1; copper is the rest.
В таблице приведены составы спеченного сплава на основе меди.The table shows the compositions of the sintered alloy based on copper.
Олово и цинк уменьшают плотность сплава, незначительно упрочняют его. Никель, железо, хром улучшают антифрикционные свойства сплава, повышают твердость. Вольфрам и молибден способствуют измельчению зерна, способствуют выравниванию свойств изделий в различных по толщине сечениях.Tin and zinc reduce the density of the alloy, slightly harden it. Nickel, iron, chromium improve the antifriction properties of the alloy, increase hardness. Tungsten and molybdenum contribute to the grinding of grain, contribute to the alignment of the properties of products in sections of various thicknesses.
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°С.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.
