| Summary: | Title screen In the paper, simulation of the treatment of two silica crystals with an amorphous interlayer was carried outusing the method of molecular dynamics. The three-body interatomic interaction suggested by Tersoff was used. Westudied sliding behavior under two different thermal conditions: ambient and elevated temperature. The simulation resultshave revealed several processes realized in the contact area caused by a shear loading. Depending on temperature andvalue of external compression, we observed smooth sliding or stick-slip motion of silicon and oxygen atoms withinamorphous interlayer. We compare the time dependencies of resistance forces for the studied specimens. In spite ofloading conditions even in case of stick-slip sliding the mean value of resistance force for simulated specimens is verylow. The last can explain the experimentally observed low friction properties of polymer nano-composite materials withsilica nanoparticles inclusions.
