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.%: алюминий 0,1-20,0; кремний 0,1-20,0; ванадий 0,1-20,0; церий 0,1-20,0; медь - остальное [1].Known sintered alloy based on copper, containing, wt.%: Aluminum 0.1-20.0; silicon 0.1-20.0; vanadium 0.1-20.0; cerium 0.1-20.0; copper - the rest [1].

Задачей изобретения является уменьшение плотности сплава.The objective of the invention is to reduce the density of the alloy.

Технический результат достигается тем, что в спеченном сплаве на основе меди, содержащим алюминий и церий, компоненты находятся при следующем соотношении, мас.%: алюминий 25,0-30,0; церий 0,1-0,2; медь - остальное.The technical result is achieved by the fact that in a sintered alloy based on copper containing aluminum and cerium, the components are in the following ratio, wt.%: Aluminum 25.0-30.0; cerium 0.1-0.2; 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.

Алюминий уменьшает плотность сплава на основе меди. Церий способствует образованию мелкозернистой структуры сплава, выравниванию свойств изделий в различных по толщине сечениях. Плотность предложенного сплава по сравнению с прототипом [1] уменьшится на 5-7 %.Aluminum reduces the density of the copper-based alloy. Cerium promotes the formation of a fine-grained alloy structure, the alignment of product properties in sections of various thicknesses. The density of the proposed alloy compared with the prototype [1] will decrease by 5-7%.

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.
