Abstract
Description
Изобретение относится к области порошковой металлургии, а именно к составам спеченных антифрикционных материалов на основе железа, которые могут быть использованы для работы в несущих или направляющих узлах.The invention relates to the field of powder metallurgy, and in particular to compositions of sintered antifriction materials based on iron, which can be used to work in bearing or guide assemblies.
Известен спеченный антифрикционный материал на основе железа, содержащий, мас. %: дисульфид молибдена 2,0-3,6; медь 7,0-15,0; никель 1,0-1,5; железо - остальное [1].Known sintered antifriction material based on iron, containing, by weight. %: molybdenum disulfide 2.0-3.6; copper 7.0-15.0; nickel 1.0-1.5; iron - the rest [1].
Задача изобретения - повышение прочности материала.The objective of the invention is to increase the strength of the material.
Технический результат достигается тем, что спеченный антифрикционный материал на основе железа, включающий дисульфид молибдена, медь, никель, железо, дополнительно содержит вольфрам, кобальт, бор и алюминий при следующем соотношении компонентов, мас. %: дисульфид молибдена 2,0-3,0; медь 2,0-2,5; никель 5,0-7,0; вольфрам 0,05-0,1; кобальт 1,25-1,75; бор 0,05-0,1; алюминий 0,05-0,1; железо - остальное.The technical result is achieved in that the sintered antifriction material based on iron, including molybdenum disulfide, copper, nickel, iron, additionally contains tungsten, cobalt, boron and aluminum in the following ratio of components, wt. %: molybdenum disulfide 2.0-3.0; copper 2.0-2.5; nickel 5.0-7.0; tungsten 0.05-0.1; cobalt 1.25-1.75; boron 0.05-0.1; aluminum 0.05-0.1; iron is the rest.
В таблице приведены составы спеченного антифрикционного материала на основе железа.The table shows the compositions of the sintered antifriction material based on iron.
В составе спеченного материала на основе железа компоненты проявляют себя следующим образом. Дисульфид молибдена незначительно снижает прочность материала, но необходим для обеспечения его износостойкости, препятствует образованию заусениц при трении. Никель улучшает металлическую основу материала. Медь, никель, кобальт, вольфрам, алюминий повышают прочность материала, препятствуют возникновению и развитию трещин при механических нагрузках. Алюминий способствует измельчению зерна.In the composition of the sintered material based on iron, the components manifest themselves as follows. Molybdenum disulfide slightly reduces the strength of the material, but is necessary to ensure its wear resistance, prevents the formation of burrs during friction. Nickel improves the metal base of the material. Copper, nickel, cobalt, tungsten, aluminum increase the strength of the material, prevent the occurrence and development of cracks under mechanical stress. Aluminum contributes to grain refinement.
Материал получают путем прессования по давлением 3,5 т/см2 смеси порошков компонентов в изделия необходимой формы и последующего спекания в атмосфере инертных газов или вакууме.The material is obtained by pressing at a pressure of 3.5 t / cm 2 a mixture of the powders of the components into products of the desired shape and subsequent sintering in an atmosphere of inert gases or vacuum.
