Nano-Modifier for Tribological Properties of Machine Components

The paper presents physicochemical investigations of structure and properties of nano-modifier synthesized from the local raw material, namely, peat obtained by its pyrolysis in air-free conditions. This nano-modifying additive is a combination of various forms of nanocarbon and polar and non-polar adsorbing materials such as silica (SiO₂), calcium carbonate (CaCO₃) and carbon (C). Test results of the type TMT-600 modifier (RF Patent N 107151) show that its different percentage is required to modify tribological properties of the steel tribocouple under different loading conditions. At 0,5 wt.% content of this nano-modifier, stabilization of the friction ratio and increase of seizure load are observed.
