Effect of the composition of mineral and organomineral mixtures on the tribological properties of friction pairs

We have studied the tribological properties of friction pairs of chromium-plated steel parts after processing with geomaterials: serpentinite, a natural silicate, a mixture of serpentinite and the silicate, a polysaccharide-modified natural silicate, and a mixture of serpentine and the polysaccharide-modified silicate. The abrasive used was quartz dust ranging in particle size from 1 to 5 μm, whose concentration reached 1%. The mixtures were shown to be highly effective in producing composite coatings on friction surfaces of parts. The incorporation of the polysaccharide-modified silicate into a friction joint considerably reduces its coefficient of friction and, as a consequence, the energy level of contact interaction.
