Study of lubricating compositions based on polyorganosiloxanes involving azomethine metalocomplexes

Azomethine complexes of copper, nickel, cobalt, and zinc are demonstrated to favor selective transfer in the medium of polyorganosiloxanes. In studies of the friction surfaces with the use of methods of optical and scanning electron microscopy, energy-dispersion electron probe X-ray microanalysis, and infrared frustrated total internal reflection spectroscopy, the formation of a transition-metal and tribopolymer film containing polyorganosiloxane fragments is found.
