The wear resistance of polyamides PA6, PA66 and PA6 based composites: PA6 + 30GF, PA6 + 30CF, PA6 + MoS2, PA6 + Oil was determined according to the method of model triboexperimental studies of materials during sliding friction. They are widely used in metal-polymer gears and plain bearings operating in conditions of dry sliding friction. Their wear resistance indicators are established, on the basis of which the characteristics of their wear resistance are determined, as used in the calculation methods of these hybrid tribomechanical systems. Quantitative regularities of tribological behavior of the specified polyamides in tribocouples with steel 45 are established. The results of influence of loading on change of coefficients of sliding friction are given.
