Description

(54) ТВЕРДЫЙ СМАЗОЧНЫЙ МАТЕРИАЛ(54) SOLID LUBRICATING MATERIAL

используют в качестве наполнител  дл  изготовлени  электрощеток.used as a filler for making electrical brushes.

Были проведены испытани  на четырех шариковой машине трени  при 400°С и удельной нагрузке до 30000 кгс/см.Tests were carried out on a four ball friction machine at 400 ° C and a specific load up to 30,000 kgf / cm.

В результате испытаний было вы снено, что с увеличением содержани  вольфрамата кали  в композиции значительно улучшаютс  lee противоизносные свойства. Так, уже при содержании в композиции 5,0% K2WO4 износ снижаетс  по сравнению с исходным графитом почти в два раза, при этом нагрузка заедани  (Рк) возрастает незначительно (от 30 до 40 кг). В композици х, содержаш,их 11% K2WO4 и выше, значение Рк превышают 90 кг, что указывает на увеличение долговечности смазки в несколько раз.As a result of the tests, it was found that with an increase in the potassium tungstate content in the composition, the lee anti-wear properties are significantly improved. Thus, already at a content of 5.0% K2WO4 in the composition, the wear is reduced almost twice as compared with the initial graphite, while the load of sticking (Pk) increases slightly (from 30 to 40 kg). In compositions containing 11% of their K2WO4 and higher, the Pk value exceeds 90 kg, which indicates an increase in lubricant durability by several times.

В таблице приведены данные по гигроскопичности исходного и легированного графита, из которых видно, что присадка до 11% вольфрамата кали  незначительно увеличивает гигроскопичность графита.The table shows the data on the hygroscopicity of the original and doped graphite, from which it is clear that the additive to 11% potassium tungstate slightly increases the hygroscopicity of graphite.

Предмет изобретени Subject invention

Твердый смазочный материал на основе углеродистого наполнител , например графита, легированного соединени ми молибдена или вольфрама, отличающийс  тем, что, с целью повышени  смазочных свойств материала , в качестве легирующей добавки введен вольфрамат или молибдат кали  в количестве 5-11 вес. %.Solid lubricant based on carbon filler, for example, graphite doped with molybdenum or tungsten compounds, characterized in that, in order to increase the lubricating properties of the material, tungstate or potassium molybdate in the amount of 5-11 wt. %
