Description
Изобретение относится к области металлургии и касается спеченных сплавов на основе железа, которые могут быть использованы для изготовления уплотнительных колец.The invention relates to the field of metallurgy and relates to sintered alloys based on iron, which can be used for the manufacture of o-rings.
Известен спеченный сплав на основе железа, содержащий, мас.%; медь 20,7-31,4, фосфор 0,3-0,6; железо остальное [1]. Пластическая деформация такого сплава составляет 12-15%.Known sintered alloy based on iron, containing, wt.%; copper 20.7-31.4, phosphorus 0.3-0.6; iron the rest [1]. Plastic deformation of such an alloy is 12-15%.
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 для уплотнительных колец, содержащий медь, фосфор, железо, отличается тем, что дополнительно содержит германий, серебро, церий и ниобий при следующем соотношении компонентов, мас.%: медь 30,0-32,0; фосфор 0,1-0,15, германийThe technical result is achieved in that the sintered alloy based on iron for o-rings containing copper, phosphorus, iron, is characterized in that it additionally contains germanium, silver, cerium and niobium in the following ratio of components, wt.%: Copper 30,0-32 0; phosphorus 0.1-0.15, germanium
0,005-0,009; серебро 0,1-0,15; церий 0,25-0,35; ниобий 0,05-0,09; железо остальное.0.005-0.009; silver 0.1-0.15; cerium 0.25-0.35; niobium 0.05-0.09; iron the rest.
В таблице приведены составы спеченного сплава на основе железа для уплотнительных колец.The table shows the compositions of the sintered iron-based alloy for o-rings.
В составе сплава компоненты проявляют себя следующим образом. Медь, германий и серебро повышают прочность и пластичность сплава, фосфор способствует повышению его твердости. Церий и ниобий придают структуре сплава мелкозернистость.In the composition of the alloy, the components manifest themselves as follows. Copper, germanium and silver increase the strength and ductility of the alloy, phosphorus increases its hardness. Cerium and niobium give the alloy structure a fine grain.
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°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 ° C for 5-6 hours in vacuum.
