Description

Изобретение относитс к области порошковой металлургии и может быть использовано при изготовлении металлокерамических антифрикционных материалов.The invention relates to the field of powder metallurgy and can be used in the manufacture of metal-ceramic anti-friction materials.
Известен сплав на основ е свинца, содержащий 44 - 75 % инди .A lead based alloy containing 44–75% indium is known.
Дл повышени антифрикционных свойств предлагаетс в сплав на основе свинца вводить 2 - 20 вес.% инди .To improve the antifriction properties, it is proposed to introduce 2 to 20 wt.% Indie into the lead based alloy.
Описываемый сплав служит металлической смазкой дл пропитки пористых металлокерамических материалов.The described alloy serves as a metal lubricant for the impregnation of porous cermet materials.
Получение антифрикционного материала путем пропитки пористой бронзы предложенного состава осуществл ют следующим образом.Obtaining antifriction material by impregnation of porous bronze of the proposed composition is carried out as follows.
Каркас из пористой бронзы изготавливают спеканием образцов в остроосушенном водороде в течение 1 час. Спеченные образцы помещают в ванну с расплавом - смазкой, нагретую до температуры 400°С и наход щуюс в среде водорода. Пропитку осуществл ют в течение 2 мин. После пропитки образцы охлаждают в среде водорода до 150°С со скоростью 2 град/мин, после чего их охлаждают на воздухе .The framework of porous bronze is made by sintering the samples in sharply dried hydrogen for 1 hour. The sintered samples are placed in a melt-lubricated bath heated to a temperature of 400 ° C and surrounded by hydrogen. The impregnation is carried out for 2 minutes. After impregnation, the samples are cooled in hydrogen to 150 ° C at a rate of 2 deg / min, after which they are cooled in air.
Пориста бронза, иролитанна ОПисываемым сплавом - смазкой, испытываетс на трение и износ в вакууме 210 мм рт. ст. при скорости скольжени 1 м/сек и различных нагрузках от 10 до 120 кг/см в паре с валом-роликом из титанового сплава с азотированной поверхностью .Porous bronze and solubilized with a painted alloy lubricant is tested for friction and wear in a vacuum of 210 mm Hg. Art. at a sliding speed of 1 m / s and various loads from 10 to 120 kg / cm paired with a roller-roller made of titanium alloy with a nitrated surface.
Результаты испытаний приведень в таблице .The test results are in the table.
mmmm
Линейный износ пары трени при испытании указанных в таблице смазок п|ри нагрузках, не цревышающих предельно допустимые, составл ет 15 - 25 мк на 1 км. Предложенный сплав-смазка обладает высокими антифрикционными свойствами и допускает более высокие нагрузки на пару трени .The linear wear of the friction pair during the testing of the lubricants indicated in the table for loads that are not exceeding the maximum allowable amounts is 15-25 microns per kilometer. The proposed alloy-lubricant has high anti-friction properties and allows for higher loads on a pair of friction.
