Description
Изобретение относитс к испытани м материалов трением, а именно к способам определени фрикционных с ойств материалов в экстремальных услови х,The invention relates to the testing of materials by friction, and specifically to methods for determining frictional properties of materials under extreme conditions,
Целью изобретени вл етс снижение трудоемкости определени нагрузки перехода от упругого к пластическому виду контактного взаимодестви поверхностей трени з.а счет измерений параметра, характеризующего определ емую нагрузку и не тре- .букидего оста н рвк-и процесса трени и 1 4-эбор;ки испытуемой пары.The aim of the invention is to reduce the laboriousness of determining the load of the transition from the elastic to plastic type of contact interaction between the friction surfaces by measuring the parameter characterizing the determined load and not necessarily remaining at the friction process and 1 4 ebs; couples.
-Ца/черт еже показан пример закономерности изменени работы выхода -Электрона ( дКТ) от величины сжимающей нагрузки ((j) .An example of the regularity of the change in the work function of the electron (DKT) versus the magnitude of the compressive load ((j).
Пример. Испытуемый образец и контртело устанавливают на машину трени , оснащенную устройством дл непрерьгоного контрол работы выхода электрона трущейс поверхности. Затем осуществл ют трение образцов и постепенно повышают сжимающую нагрузку . Одновременно измер ют работу выхода электрона трущейс поверхности и определ ют разность между двум соседними ее значени ми. Така операци эквивалентна нахождению производной от работы выхода электрона по нагрузке. Положение максимума зависимости работы выходу электрона от нагрузки соответствует нулевой разнице двух последовательных измерений .Example. The test sample and the counterbody are mounted on a friction machine equipped with a device for the non-direct control of the electron work function of the rubbing surface. Then the samples are rubbed and the compressive load is gradually increased. At the same time, the electron work function of the rubbed surface is measured and the difference between its two adjacent values is determined. Such an operation is equivalent to finding the derivative of the electron work function with respect to the load. The position of the maximum dependence of the work on the electron output on the load corresponds to the zero difference of two consecutive measurements.

Нагрузку, соответствующую положению нулевой разницы измерений, принимают за нагрузку перехода от упругого к пластическому виду контактного взаимодействи поверхностей трени . Изобретение основано на том, что максимум зависимости работы выхода электрона от нагрузки соответствует нагрузке перехода от упругого к плас- тическому виду контактного взаимодействи поверхностей трени .The load corresponding to the position of the zero difference of measurements is taken as the load of the transition from the elastic to plastic form of the contact interaction of the friction surfaces. The invention is based on the fact that the maximum dependence of the electron work function on the load corresponds to the load of the transition from the elastic to the plastic form of the contact interaction of the friction surfaces.
