Tribotechnical characteristics of powder composite materials based on copper in high-speed friction

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.
