| Abstract: | Conclusions Copper and the composite materials based on copper (with mullite, glass ceramic, and also sulfur and molybdenum sulfide) have a high friction coefficient (0.23–0.46), a medium temperature of the friction surface (130–270°C), and are susceptible to bonding with the contacting surface (07Khl6N6 steel).The materials containing 10% graphite, sulfur, and molybdenum disulfide have a low friction coefficient (0.09–0.15), do not bond to 07Khl6N6 steel, and can be recommended for service in high-speed friction units.Translated from Poroshkovaya Metallurgiya, No. 7(283), pp. 52–56, July, 1986. |
