Abstract

FIELD: antifriction materials. SUBSTANCE: mixture of abrasive-like powder with binder is prepared, and powder is treated preliminary with dry saturated steam at 110-115 C for 20-25 min in centrifuge placed into barocamera. Then prepared mixture is activated mechanically, placed between friction surfaces and broken in. Composition given in invention description is used as abrasive-like powder. EFFECT: improved method of film forming.

Description

Изобретение относится к машиностроению и может быть использовано в узлах с трущимися поверхностями. The invention relates to mechanical engineering and can be used in units with rubbing surfaces.

Известен способ формирования сервовитной пленки триботехническим составом, при котором между трущимися поверхностями размещают абразивоподобный порошок, преимущественно состоящий из природного серпентина и связующего. Смесь связующего и порошка предварительно механоактивируют. A known method of forming a servo-like film with a tribotechnical composition, in which an abrasive-like powder, mainly consisting of natural serpentine and a binder, is placed between the rubbing surfaces. A mixture of a binder and a powder is pre-mechanically activated.

Предложенный способ может значительно повысить устойчивость сервовитной пленки за счет дисперсии и обезвоживания порошка, для чего предлагается в качестве абразивного порошка использовать смесь, мас. Серпентин 51-60 Тальк 20-30 Сера в равной Пирротин 8-10 пропорции Энстатит Фаялит
Для обезвоживания и размельчения порошка сначала порошок помещают во вращающуюся центрифугу и обрабатывают в течение 20-30 мин сухим насыщенным паром, добавляют связующее и механоактивируют смесь, а затем сразу же производят приработку трущихся поверхностей.
The proposed method can significantly increase the stability of the servovitic film due to the dispersion and dehydration of the powder, for which it is proposed to use a mixture, wt. Serpentine 51-60 Talc 20-30 Sulfur in equal Pyrrhotite 8-10 proportions Enstatite Fayalit
To dehydrate and grind the powder, the powder is first placed in a rotating centrifuge and treated with dry saturated steam for 20-30 minutes, a binder is added and the mixture is mechanically activated, and then the rubbing surfaces are run-in immediately.

Серпентин (Mg6-xAlx)(Si4-xAlx)O10(OH)8, где x=0,75-58 Тальк MgSi4O10(OH)2 33 Сера S Пирротин FeS 9 в равной Энстатит MgSiO3 пропорции Фаялит (Fe0,94Mg0,06)2SiO4
помещали в центрифугу и вращали с 1500 об/мин. Центрифугу помещали в барокамеру, в которой создавали режим насыщенного пара с температурой 110оС, обрабатывали порошок в течение 20 мин.

placed in a centrifuge and rotated from 1500 rpm The centrifuge was placed in a pressure chamber in which saturated steam created mode with temperature 110 C, the powder was treated for 20 min.

Обработанный порошок (НИОД-2) мешали с дисперсным стеарином. Приготовленную смесь подвергли механоактивации на виброустройстве 7 мин. The treated powder (NIOD-2) was mixed with dispersed stearin. The prepared mixture was subjected to mechanical activation on a vibration device for 7 minutes.

Готовую смесь ввели в зону трения и прирабатывали при давлении 0,01-1 МПа. В процессе приработки на трущихся поверхностях формируется сервовитная пленка, позволяющая значительно снизить коэффициент трения в узлах трения. Обработка порошка сухим насыщенным паром при одновременном его распылении эффективно обезвоживает его без спекания и одновременно делает его воздушным и дополнительно стабилизирует его дисперсность. Это в конечном счете повышает устойчивость формируемой сервовитной пленки. The finished mixture was introduced into the friction zone and worked in at a pressure of 0.01-1 MPa. In the process of running-in, a servo-like film is formed on the rubbing surfaces, which can significantly reduce the friction coefficient in the friction units. Processing the powder with dry saturated steam while spraying it effectively dehydrates it without sintering and at the same time makes it airy and additionally stabilizes its dispersion. This ultimately increases the stability of the formed servovitic film.
