Synthesis, structure and tribological properties of nanocomposite materials in the system of potassium polytitanate – layered double hydroxide – serpentinite

The synthesis of some nanocomposite materials in the ternary system of potassium polytitanate (PPT)-layered double hydroxide (LDH)-synthetic serpentinite (SS) is considered. The tribology behavior of some model greases obtained by introduction of different nanocomposite additives in the universal industrial grease of the Litol-24 trademark is investigated using standard testing procedures. The obtained results have shown that the synthesized nanopowders improve anti-friction and anti-wear properties of the standard lubricating composition. It is shown that the enhanced tribology performance is attributed to a complex layered structure of the produced nanocomposites and their chemical interaction with a worn surface of the metal.
