The Cu-10 Sn friction material was fabricated by powder metallurgy

and the influence of CoCrFeNiAl content on the structure and friction and wear properties of the composites was explored. The results indicate that different contents CoCrFeNiAl particles different contents with can coexist stably with Cu-10 Sn matrix particles

which presents mechanical bonding and metallurgical bonding. The hardness of the material without CoCrFeNiAl is the minimum

and both the friction coefficient and wear rate are greater with poor wear performance. As the content of CoCrFeNiAl increases

the hardness of the composites is increased greatly

and the friction coefficient and wear rate are firstly decreased and then increased. When the content of CoCrFeNiAl is 10% to 20%

the wear rate continues to decrease

and the friction coefficient is decreased significantly. When CoCrFeNiAl content reaches 30%

the wear rate of the composites is decreased to the minimum

and the friction coefficient is raised again

where the composites exhibit the highest hardness and the optimal wear performance

which is mainly attributed to the synergy between the added phase particles and the matrix.
