Abstract
The paper describes the tribotechnical properties of thin-film coatings obtained by the tribotechnical modification of 40X grade steel with different organic and inorganic tribotechnical materials (natural inorganic and artificial polymers), as well as with composite materials based on vermiculite. Comparative tribotechnical investigations revealed that composites possess better tribotechnical properties than single-component materials. The most promising materials for the tribotechnical modification of steel friction surfaces are vermiculite-based nanostructured composites that provide minimal friction coefficient and high wear resistance under the conditions of boundary friction. The tribotechnical properties of polymagnesiumphenylsiloxane are a little worse than that of the materials based on vermiculite. Polymagnesiumphenylsiloxane and nanostructured composites based on vermiculite can be used as additives to motor oils and solid lubricants, as well as for the modification of friction surfaces during manufacturing or reconditioning of machine parts to increase their durability.
