Изобретение относитс к области испытани материалов и касаетс способа определени коэффициента трени .The invention relates to the field of material testing and relates to a method for determining the coefficient of friction.
Известен способ определени коэффициента трени , заключающийс в том, что образец ввод т в контакт с другим образцом с заданной силой, сдвигают их друг относительно друга и измер ют силу сдвига, по которой суд т о величине коэффициента трени 1.A known method for determining the friction coefficient is that the sample is brought into contact with another sample with a given force, shifted against each other and the shear force measured, according to which the value of the coefficient of friction 1 is measured.
Недостатком известного способа вл етс сложность определени коэффициента трени в различных средах.The disadvantage of this method is the difficulty of determining the coefficient of friction in various environments.
Ближайшим к изобретению техническим решением вл етс способ определени коэффициента трени материала, заключающийс в том, что поверхность материала облучают рентгеновскими лучами, измер ют интенсивность их отражени , по которой суд т о коэффициенте трени материала 2.The closest technical solution to the invention is a method for determining the coefficient of friction of a material, which consists in irradiating the surface of a material with X-rays, measuring the intensity of their reflection, according to which the coefficient of friction of material 2 is judged.
Однако этот способ позвол ет определить коэффициенты трени только качественно, так как низка точность не позвол ет количественно оценить значений коэфициентов трени , особенно покрытий дисульфида молибдена .However, this method allows one to determine friction coefficients only qualitatively, since low accuracy does not allow one to quantify the values of friction coefficients, especially molybdenum disulfide coatings.
Целью изобретени вл етс повышение точности определени коэффициента трени покрытий дисульфида молибдена, образованных на молибденовой подложке диффузионным способом.The aim of the invention is to improve the accuracy of determining the friction coefficient of molybdenum disulfide coatings formed on a molybdenum substrate by diffusion method.
Дл этого по предлагаемому способу измер ют интенсивность дифракционных отражений от кристаллических плоскостей с индексами 0001 и 100, а величину коэффициента трени определ ют из соотношени For this, according to the proposed method, the intensity of diffraction reflections from crystal planes with indices 0001 and 100 is measured, and the value of the friction coefficient is determined from the ratio
/ 0,03 +0,0056- в-,/ 0.03 + 0.0056- in,
где / 0002 и / 100 -интенсивности отражени от кристаллических плоскостей с индексами 0001 и 100 соответственно. Способ заключаетс в следующем. Образец покрыти дисульфида молибдена, образованного на молибденовой подложке диффузионным способом, подвергают облучению рентгеновскими лучами, выдел ют углы дифракции дисульфида молибдена дл кристаллических плоскостей с индексами 0001 и 100 и измер ют интенсивность их отражеНИИ / 0002 и / 100 соответственно. Величину коэффициента трени определ ют из уравнени where / 0002 and / 100 are the reflection intensities from the crystal planes with the indices 0001 and 100, respectively. The method is as follows. The molybdenum disulfide coating sample formed on the molybdenum substrate by diffusion was subjected to X-ray irradiation, molybdenum disulfide diffraction angles were measured for the crystal planes with indices 0001 and 100 and their reflection intensity was measured in / 0002 and / 100, respectively. The value of the coefficient of friction is determined from the equation
