Soltys L. Physical and chemical tribocontact phenomena on microrough surfaces of the polymer composite and metal.

Thesis deals with the physico-chemical phenomena on microrough surfaces of the polymer composite and metal in dynamic contact. The intensity of wear of polymer composite material based on polytetrafluoroethylene and carbon fiber in friction on rough isotropic metal surface without lubrication and in distilled water have been researched. The results of the intensity of wear carbon plastics based on polytetrafluoroethylene and carbonated carbon fibers and aromatic polyamide and graphite carbon fibers, obtained from hydrated cellulose tissues, has been resulted. It has been shown that the allocation of heights of peaks and average curvature in the peaks microirregularities surfaces of samples of polymer composites and metal counterfaces depends on the initial moments of the spectral density and formation on the conjugated metal surfaces of the intermediate films. Coatings of carbon fibers by copper by zinc technology significantly affects on the processes of formation of films on the surface of metal counterface.By results of tests on four-bullet friction machine in conditions limit loads has been shown that copper complexes with heterocycle ligands dominate copper complexes with benzene ligands by anti-welding properties, herewith bond of copper with oxygen and nitrogen simultaneously much more effective than with each element separately.
