According to the method of model triboexperimental studies of materials in sliding friction according to the scheme of end friction determined wear resistance of polyacetals POM-H and a number of composites based on it: POM + 35PTFE, POM + 20PTFE, POM + 60Bronze, POM + 20PTFE + 30Bronze; POM + 10PTFE + 20Bronze, POM + 15PTFE + 15GF, POM + 10PTFE + 10GF, POM + 10PTFE + 20Bronze + 10GF, POM + 10PTFE + 15Bronze + 5GF, polyamide PA6. They are widely used in metal-polymer (MP) 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 tribocouple with steel 45 are established. The results of influence of loading on change of coefficients of sliding friction are given.
