Abstract:
The paper presents the results of changes in the strength characteristics of thin-film coatings based on
compounds of copper-bismuth, copper-magnesium, copper-nickel. The dependences of the influence
of the phase composition on the strength characteristics, such as the coefficient of friction, bending
strength and impact coefficient, are established. The effect of irradiation with helium ions with a high
radiation dose of 10 15 -10 17 ion/cm 2 on the strength characteristics is evaluated. It is shown that an
increase in the radiation dose leads to a decrease in strength properties due to the appearance of a large
concentration of defects in the structure.
