Description
Изобретение относитс н области порошковой металлургии, s частности к фрикционным спеченный материалам на основе келеза,примен емым в фрикционных устройствах авТ01||о6илеи ,тракторов, экскаваторовThe invention relates to the field of powder metallurgy, s in particular to friction sintered kelez-based materials used in friction devices avT01 || six, tractors, excavators
ИзМбтен фрикционный спеченный материал на основе железа,содержащий алюминий,фосфор, асбест, кремнезем.Izbrit friction sintered material based on iron, containing aluminum, phosphorus, asbestos, silica.
С целью повышени коэффициента трени ,износостойкости и теплопроводности в предлагаемый фрикционный спеченный материал введены медь и графит при следующем соотношении компонентов,вес.:In order to increase the coefficient of friction, wear resistance and thermal conductivity, copper and graphite were introduced into the proposed friction sintered material with the following ratio of components, weight .:
0,2-50.2-5
ГрафитGraphite
Железо Остальное Предлагаемый материал получают путем приготовлени шихты из соот ветствующих компонентов,прессовани фрикционного сло под давлением 5-ь т/см% спекани фрикцнонша злементов.в защитно атмосфере прв 1020-1060 С под давлением кг/см течение двух часов.Iron Else The proposed material is obtained by preparing a mixture of the corresponding components, pressing the friction layer under a pressure of 5 tons / cm% by sintering frictional elements in a protective atmosphere of 1020-1060 ° C under a pressure of kg / cm for two hours.
