    ENG: Antifriction coatings based on aromatic phenylene polyamide (phenylone) were developed by introducing a copper arylamide complex with benzimidazole-2-thiocarboxylic acid as a modifying additive. The tribological properties of the phenylene-modifying additive system were investigated, focusing on the nature and concentration of the modifying additive in the polymer composition. The influence of the additive on the microhardness of the polymer coatings was assessed. The introduction of the copper arylamide complex with benzimidazole-2-thiocarboxylic acid as a modifying additive resulted in changes to the polymer matrix structure, forming strong chemical bonds between polymer chains, which improved the strength of materials and reduced its wear susceptibility. The tribological properties of the modified coatings were characterized by a lower coefficient of friction and better wear resistance compared to unmodified coatings. The developed coatings can be widely applied in various industries, such as mechanical engineering, aviation, and automotive, offering benefits such as enhanced durability, wear protection, and reduced maintenance costs. Additionally, their use can contribute to lower energy consumption and reduced environmental impact.
