Description
Изобретение касаетс порошковой металлургии,в частности композиционных самосмазывающихс материалов на основе бронзы, содержащих твердую смазку,которые могут быть использованы s качестве антифрикционных материалов в узлах суts oro трени машин,работающих в вакууме . Известен спеченный самосмазывающийс материал на основе бронзы содержащий твердую смазку,в качест ве которой могут быть использованы дисульфиды или диселениды вольфрамa ,мo шбдeнa и других тугоплавких металлов в количестве 1-50. Целью изобретени вл етс повышение механической прочности и износостойкости спеченного материала . Дл этого в предложенный материал введен сплав,выбранный из группы,содержащей никель-фосфор, кобальт-фосфор,в количестве 12-30 вес.. Сплав никель-фосфорввод т в композиционный материал путем осавдени его в виде: покрыти толщиной 1-2,5 мкм на частицах дисульфида молибдена,например,химическим; способом. Порошок плакированного дисульфида молибдена смешивают с порошком бронзы () и смесь подвергают гор чему прессованию при температуре 400-8000С и давлении 50-100 кг/см2. Удельный вес полученного материала 8 г/см ппочность на раст жение 25 кгс/см,коэффициент трени 0,18-0,20 ,весовой износ 4 10-4 г;км. ПРЕЩМЁТ ИЗОБРЕТЕШИ Самосмазывающийс спеченный материал на основе бронзы, содержащий дисульфид молибдена,отличающийс тем,что,с целью, увеличени механической прочности и износостойкости в него введен сплав,выбранный из группы,содержащей никель фосфор ,кобальт фосфор,при , . 3 слежщем соотношении в ее /о Сплав, компонентов,выбранный 10 . 433231 - 4 jrg ГЦиППН кобальт :фосфор 12-30 Бронза остальноеThe invention relates to powder metallurgy, in particular self-lubricating composite materials based on bronze, containing solid lubricants, which can be used as antifriction materials in the assemblies of the friction of machines operating in vacuum. A sintered, self-lubricating bronze-based material containing a solid lubricant is known, in which 1–50 disulfides or diselenides of tungsten, mosenium and other refractory metals can be used. The aim of the invention is to increase the mechanical strength and wear resistance of the sintered material. For this purpose, an alloy selected from the group consisting of nickel-phosphorus, cobalt-phosphorus, in an amount of 12-30 weight is introduced into the material. The alloy of nickel-phosphorus is introduced into the composite material by making it in the form of a coating with a thickness of 1-2.5 µm on molybdenum disulfide particles, for example, chemical; in a way. The powder of clad molybdenum disulfide is mixed with bronze powder () and the mixture is hot pressed at a temperature of 400-8000С and a pressure of 50-100 kg / cm2. The specific weight of the material obtained was 8 g / cm strength per tensile 25 kgf / cm, friction coefficient 0.18-0.20, weight wear 4 10-4 g; km. BACKGROUND OF INVENTION A self-lubricating bronze-based sintered material containing molybdenum disulfide, characterized in that, in order to increase the mechanical strength and wear resistance, an alloy selected from the group containing nickel phosphorus, cobalt phosphorus, is introduced into it. 3 Tracking ratio in her / o alloy, components selected 10. 433231 - 4 jrg GTsPPN cobalt: phosphorus 12-30 Bronze the rest
