Изобретение относитс к области порошковой - металлургии.This invention relates to the field of powder metallurgy.
Известен способ изготовлени спеченных пористых изделий, включающий обработку пористых спеченных заготовок в парах кар- бонипа никел или железа, в результате которой металл или окисел металла осаждаетс в порах заготовки.A known method of manufacturing sintered porous products involves the processing of porous sintered billets in carbon-nickel or iron vapors, as a result of which metal or metal oxide is deposited in the pores of the billet.
С целью насыщени пористых изделий свободным углеродом по предлагаемомуIn order to saturate porous products with free carbon according to the proposed
способу обработку провод т при давлении 50-65 атм и температуре 320-350°С.The method of processing is carried out at a pressure of 50-65 atm and a temperature of 320-350 ° C.
Способ осуществл етс следующим образом- .The method is carried out as follows.
Порощок меди перемешивают с металли- ческим порошком парообразовател -. The copper powder is mixed with a metal steam generator powder.
Из полученной смеси под давлением 1000 кг/CM прессуют заготовки, которые затем спекают в водороде при 8ОО С в течение 10 мин.From the mixture obtained, under a pressure of 1000 kg / CM, blanks are pressed, which are then sintered in hydrogen at 8OO C for 10 minutes.
После спекани порообразователь удал ют из материала заготовок, экстрагиру его при давлении 180 ат и температуре 16О С в течение до 60 мин. Полученные пористые заготовки обрабетывают в парах образовавшегос вреаультате экстракции тетракарбо.нила никел при 350 С и давлении 50 ат, после чего температуру и давление снижают до нормального . При этом процесс термического, разложени окиси углерода протекает непосредственно в порах материала изделий, .After sintering, the blowing agent is removed from the material of the preform, extracting it at a pressure of 180 at and a temperature of 16 ° C for up to 60 minutes. The obtained porous preforms are processed in vapors of tetracarboxylated nickel formed during the extraction of nickel at 350 ° C and a pressure of 50 atm, after which the temperature and pressure are reduced to normal. The process of thermal decomposition of carbon monoxide proceeds directly in the pores of the material of products,.
В результате обработки получают пористые издели , поры которых заполнены чистым дисперсным высокоактивным свободным (углеродом.As a result of processing, porous products are obtained, the pores of which are filled with pure dispersed highly active free (carbon.
I В случае необходимости графитировани рбразрэавшегос в порах изделий свободно- ро углерода обработанные издели нагреваю до 1000-2000 С в соответствии с термостойкостью компонентов материала изделий.I If it is necessary to graphitize the pores in the pores of free carbon products, the processed products are heated to 1000–2000 ° C in accordance with the heat resistance of the components of the material of the products.
ПРЕДМЕТ ИЗОБРЕТЕНИЯSUBJECT OF INVENTION
Способ изготовлени спеченных пбристьи изделий, включающий обработку спеченных заготовок в парах карбонила металла, о тличающийс тем, что, с целью насыщени пористых изделий свободным уг леродом, обработку провод т при давлении 5О-65 ат и температуре 320-35О С.A method of manufacturing sintered articles of bristles, including processing sintered billets in metal carbonyl vapors, differing in that, in order to saturate porous products with free carbon, the treatment is carried out at a pressure of 5 O-65 at and a temperature of 320-35 ° C.
