A comparative analysis of the results of tribological tests of the basic MS 5123-2 grease with a complex two-component (liquid and frame) structure before and after the addition of 45 microns of copper particle powder with different concentrations was carried out. It is shown that the wear rate of (I) balls (from WX15) during 10-second tests in a lubricant with the addition of copper particles with a concentration of 0.5 and 1.0% turned out to be 2.1192 10-7 and 1.2037 10-7, respectively, which compared with the base MS 5123-2 (I = 2.2489 10-7), turned out to be 1.1- and 1.9-times lower times, respectively. The wear index (Di) of the balls (made of steel SHX15) during a 1-hour test in a lubricant with the addition of copper particles with a concentration of 0.5 and 1.0% turned out to be 0.697 and 0.525 mm, respectively, which, compared with the base MS 5123-2 (Di = 1.03 mm), turned out to be 1.5 and 2.0 times less, accordingly. Metallographic studies have shown that with an increase in the concentration of copper particles, there was an increase in the size of the frame grains in the grease and a decrease in its strength.
