| Abstract: | Conclusion 1. The antifrictional properties of metallopolymer compositions made up by a thermal method in an air atmosphere (method A) and in a hydrogen atmosphere (method B), and also made up by mechanical mixing of P610 polyamide powders and PM grade copper (method C) have been investigated.2. It has been shown that the metallopolymer obtained by the thermal method in a hydrogen medium, at a degree of filling of 30% or more by wt., has less wear of the composition as compared with compositions made up by method C which are similar in degree of filling.3. Compositions made up by method A have a loosened structure and are comparable in wear resistance with the unfilled polymer.4. The coefficient of friction of the metallopolymer obtained in a hydrogen medium is less at the selected slippage regime than the coefficient of friction of the pure polyamide by a factor of 1.5, and is 20% less than that of the metal-filled composition made up by mechanical mixing in accordance with method C.5. It has been shown that the temperature on the friction surface of the metallopolymer made up by method B is less than that of the pure polyamide or the metal-filled composition made up by method C, by 40°C and by 20°C, respectively.Lenin Young Communist League.
