Abstract
Description
Изобретение относится к области металлургии и касается спеченных фрикционных материалов на основе меди, используемых, например, для изготовления деталей тормозных устройств.The invention relates to the field of metallurgy and relates to sintered friction materials based on copper, used, for example, for the manufacture of parts of brake devices.
Известен спеченный фрикционный материал на основе меди, содержащий, мас.%: цинк 7,0-15,0; железо 0,1-7,0; свинец 0,5-12,0; графит 1,0-10,0; вермикулит 1,5-20,0; медь - остальное [1].Known sintered friction material based on copper, containing, wt.%: Zinc 7.0-15.0; iron 0.1-7.0; lead 0.5-12.0; graphite 1.0-10.0; vermiculite 1.5-20.0; copper - the rest [1].
Задачей изобретения является повышение износостойкости материала.The objective of the invention is to increase the wear resistance of the material.
Технический результат достигается тем, что спеченный фрикционный материал на основе меди, содержащий цинк, железо, свинец, графит, вермикулит, медь, дополнительно включает хром, сурьму и кремний, при следующем соотношении компонентов, мас.%: цинк 6,0-8,0; железо 0,1-0,2; свинец 2,0-4,0; графит 3,0-7,0; вермикулит 8,0-12,0; хром 4,0-6,0; сурьма 0,05-0,1; кремний 2,0-3,0; медь - остальное.The technical result is achieved in that the sintered friction material based on copper, containing zinc, iron, lead, graphite, vermiculite, copper, additionally includes chromium, antimony and silicon, in the following ratio, wt.%: Zinc 6.0-8, 0; iron 0.1-0.2; lead 2.0-4.0; graphite 3.0-7.0; vermiculite 8.0-12.0; chrome 4.0-6.0; antimony 0.05-0.1; silicon 2.0-3.0; copper is the rest.
В таблице приведены составы спеченного фрикционного материала на основе меди.The table shows the compositions of the sintered friction material based on copper.
Повышение износостойкости материала на основе меди достигается за счет комплексного влияния компонентов, входящих в его состав. Цинк и свинец способствует улучшению металлической основы материала. Хром и кремний обеспечивают повышенную твердость материала, вермикулит - теплостойкость. Графит и сурьма препятствуют образованию заусениц.An increase in the wear resistance of a copper-based material is achieved due to the complex effect of the components included in its composition. Zinc and lead contribute to the improvement of the metal base of the material. Chrome and silicon provide increased hardness of the material, vermiculite - heat resistance. Graphite and antimony prevent the formation of barbs.
Фрикционный материал получают путем прессования под давлением 3,5 т/см2 смеси порошков компонентов в изделия необходимой формы и последующего спекания при температуре 950°С в течение 3-4 ч в атмосфере инертного газа или в вакууме.Friction material is obtained by pressing under pressure 3.5 t / cm 2 a mixture of the powders of the components into products of the desired shape and subsequent sintering at a temperature of 950 ° C for 3-4 hours in an inert gas atmosphere or in vacuum.
