Abstract
1. Способ получения антифрикционных порошковых материалов на основе меди, включающий приготовление шихты, состоящей из смеси порошка меди и легирующих материалов, смешивание, прессование и спекание, отличающийся тем, что в качестве легирующих материалов используют олово-порошок, порошок свинцовый, графит, а после операции спекания осуществляют последовательно калибровку и повторное спекание, причем шихта содержит компоненты при следующем соотношении, мас.%: ! олово-порошок9,5…10порошок свинцовый0,5…1,0графит0,3…0,5остальноепорошок медный электролитический ! 2. Способ по п.1, отличающийся тем, что спекание осуществляют путем последовательного увеличения температуры до 600°±5°С с выдержкой 1,5 ч и дальнейшим повышением температуры до 660°С±5°С с выдержкой 1,5 ч, и последующим охлаждением на воздухе путем обдува в потоке диссоциированного аммиака, а калибровку осуществляют при удельном давлении равном давлению прессования с последующим режимом спекания путем последовательного увеличения температуры до 860°С±5°С с выдержкой 1,5 ч и последующим охлаждением на воздухе путем обдува в потоке диссоциированного аммиака,. ! 3. Способ по п.1, отличающийся тем, что легирующие материалы засыпают в шихту последовательно по мере уменьшения их процентного состава.1. A method of producing antifriction powder materials based on copper, including the preparation of a mixture consisting of a mixture of copper powder and alloying materials, mixing, pressing and sintering, characterized in that tin powder, lead powder, graphite are used as alloying materials, and after sintering operations consistently calibrate and re-sinter, and the mixture contains components in the following ratio, wt.%:! tin powder 9.5 ... 10 lead powder 0.5 ... 1.0 graphite 0.3 ... 0.5 other electrolytic copper powder! 2. The method according to claim 1, characterized in that the sintering is carried out by successively increasing the temperature to 600 ° ± 5 ° C with a holding time of 1.5 hours and then raising the temperature to 660 ° C ± 5 ° C with a holding time of 1.5 hours, and subsequent cooling in air by blowing in a stream of dissociated ammonia, and calibration is carried out at a specific pressure equal to the pressing pressure followed by a sintering mode by successively increasing the temperature to 860 ° C ± 5 ° C with a holding time of 1.5 h and subsequent cooling in air by blowing in flow dissociated th ammonia ,. ! 3. The method according to claim 1, characterized in that the alloying materials are poured into the mixture sequentially as their percentage composition decreases.
