Abstract
Description
Изобретение относится к области порошковой металлургии и касается спеченных сплавов на основе меди, которые могут быть использованы в машиностроении.The invention relates to the field of powder metallurgy and relates to sintered alloys based on copper, which can be used in 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, by weight. %: 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, свинец, железо, дополнительно содержит фосфор, ванадий и цирконий, при следующем соотношении компонентов, мас.%: цинк 6,5-8,5; свинец 2,0-3,0; железо 0,2-0,3; фосфор 0,1-0,15; ванадий 0,15-0,2; цирконий 0,15-0,2; медь - остальное.The technical result is achieved by the fact that the sintered alloy based on copper, containing zinc, lead, iron, additionally contains phosphorus, vanadium and zirconium, with the following ratio of components, wt.%: Zinc 6.5-8.5; lead 2.0-3.0; iron 0.2-0.3; phosphorus 0.1-0.15; vanadium 0.15-0.2; zirconium 0.15-0.2; 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.
Цинк уменьшает плотность сплава, незначительно упрочняет его. Железо, фосфор повышают твердость и прочность сплава. Свинец улучшает антифрикционные свойства сплава. Ванадий и цирконий способствуют измельчению зерна, способствуют выравниванию свойств изделий в различных по толщине сечениях.Zinc reduces the density of the alloy, slightly strengthens it. Iron, phosphorus increase the hardness and strength of the alloy. Lead improves the antifriction properties of the alloy. Vanadium and zirconium 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.
