文摘

The role of the copper has been studied with the aim of reducing its concentration in brake friction materials. The design of the friction material was changed introducing two ingredients, nanostructured after ball-milling. Ball milling induced the formation of Cu-ZrO2 clusters that influence the tribological behavior of the new materials. Even in the absence of copper particles, a good friction layer is formed thanks to the wearing of copper fibers.
