Abstract
Description
Изобретение относится к области металлургии, а именно к составам спеченных сплавов на основе железа, которые могут быть использованы для изготовления уплотнительных колец.The invention relates to the field of metallurgy, and in particular to compositions of sintered alloys based on iron, which can be used for the manufacture of o-rings.
Известен спеченный сплав на основе железа, содержащий, мас.%: медь 10,0-40,0; никель 0,1-15,0; железо - остальное [1].Known sintered alloy based on iron, containing, wt.%: Copper 10.0-40.0; nickel 0.1-15.0; iron - the rest [1].
Задачей изобретения является повышение пластичности сплава.The objective of the invention is to increase the ductility of the alloy.
Технический результат достигается тем, что спеченный сплав на основе железа, включающий медь и никель, дополнительно содержит серебро, стронций и кобальт, при следующем соотношении компонентов, мас.%: медь 20,0-22,0; никель 18,0-20,0; серебро 0,16-0,2; стронций 0,005-0,01; кобальт 4,8-5,4; железо - остальное.The technical result is achieved in that the sintered alloy based on iron, including copper and nickel, additionally contains silver, strontium and cobalt, in the following ratio of components, wt.%: Copper 20.0-22.0; nickel 18.0-20.0; silver 0.16-0.2; strontium 0.005-0.01; cobalt 4.8-5.4; iron is the rest.
В таблице приведены составы сплава.The table shows the alloy compositions.
В составе сплава компоненты проявляют себя следующим образом. Медь в незначительном количестве растворяется в железе. Основная ее часть агрегируется в небольшие группы, между которыми расположено железо. Никель и кобальт образуют твердые растворы, благоприятно влияют на выравнивание механических свойств изделий. Серебро способствует измельчению структурных составляющих сплава. Стронций уменьшает количество газовых включений.In the composition of the alloy, the components manifest themselves as follows. Copper in a small amount dissolves in iron. Its main part is aggregated into small groups, between which iron is located. Nickel and cobalt form solid solutions, favorably affect the alignment of the mechanical properties of products. Silver contributes to the grinding of the structural components of the alloy. Strontium reduces the amount of gas inclusions.
Сплав получают методом порошковой металлургии путем прессования под давлением 5 т/см2 смеси порошков компонентов в изделия необходимой формы и последующего спекания при температуре 1200-1220°С в течение 5-6 ч в вакууме.The alloy is obtained by powder metallurgy by pressing under pressure 5 t / cm 2 a mixture of the powders of the components into products of the desired shape and subsequent sintering at a temperature of 1200-1220 ° C for 5-6 hours in vacuum.
