In given article process of development of antifriction coverings is considered on the basis of aromatic polyamide phenylon C-2. Thioamides and their copper compounds have been used as modifiers to obtain antifriction coatings based on aromatic polyamides. Friction and wear tests were realized at the friction machine with the lubrication with the industrial oil by the scheme shoe-disc. The dependence of the tribotechnical characteristics on the nature and concentration of the modifying additive of the elaborated polymer coatings was stated. The usage of d-addition at the amount of 1 mass % is optimal. It was shown that the friction and wear of the coating were influenced by the chemical structure of the ompound materials based on thioamides. Thus, the best quality was registered in the coating containing the modifier with Cu in its composition.

The new diagnostic tools are designed to determine a wear of friction parts and articles of different equipment in-line, without putting them out of operation and dismantling, through analysis of wear products in lubrication system.

Many friction parts of different equipment are made from anti-friction materials which include non-ferrous metals, namely, Cu, Sn, Al, and others. Sliding bearings and separators of tumbler bearings are the typical example of the said friction parts. To estimate a wear level of friction parts, a very expensive and clumsy instruments, spectrometers, are now used worldwide. To receive a reliable conclusion on current technical condition of friction parts, it’s necessary to take off an oil sample and send it to a diagnostic center to be analyzed. Therefore, implementation of new tools which allow to determine in-line a wear level of friction parts manufactured from ferrous and non-ferrous metals and alloys, is vital.
