Description
результате чего улучшаютс фрикционные свойства материала.the result is improved frictional properties of the material.
Испытани образцов - фрикционных дисков из предлагаемого материала провод тс по известной методике при скорости 2950 об/мин и давлении 20 кг/см- , позвол ющим имитировать реальные услови работы. Результаты г испытаний приведены в таблице.Testing of samples - friction discs of the proposed material is carried out according to a known method at a speed of 2950 rpm and a pressure of 20 kg / cm-1, which allows to simulate real working conditions. The results of the tests are given in the table.

Как видно из таблицы, величина коэффициента трени предлагаемого материала при повшаенвык скорост х 25 скольжени существенно вбв а/ чем у известного.As can be seen from the table, the magnitude of the coefficient of friction of the proposed material with an increased speed of 25 x slip is significantly higher than that of the known.
