摘要: Abstract Friction and wear of powder materials impregnated with commercially available layered (platelets) WS 2 (2H) inorganic fullerene-like nanoparticles (IF) were studied. Bronze–graphite, iron–graphite iron–nickel–graphite samples used in this experiment. The linear (in situ) was measured. It shown that the IF into pores improve tribological properties comparison to a reference sample or 2H solid lubricant particles. mechanisms friction have been considered. role particles lubricants has analyzed framework third body lubrication model. state before after test found shape is preserved during tests under high loads. Thin debris surrounded by spherical appear be formed provide easily sheared film (low coefficient) experiments containing nanoparticles.
